Hi All,
I'm trying to achieve the following...
   

   
 
   

   
 
But, I'm getting this error... Unterminated user-defined tag: ending tag

Please help me find a work around to this.

Hi,
I have a form with a Date:

 

The problem: the formated date is not shown at all, it should have
functioned as the value of that input.
what can I do ?

RE: Accessing bean properties problem

[Janne Mattila]

Oops, that was a typo. Should have read
" 
/>

If browsers did pick up "value" parameter, this problem would not even 
exist...

Some browsers do.  What is your problem?  Why are you adding "delete" in 
here?
There is no "name" attribute with image.  I assume you mean to use the 
"property" attribute.  There is no problem with this, even without a 
"value" attribute.  If you use "property='<%= "delete" + choiceKey %>'", 
and (in your processing of the form):

   String button = null;
   Enumeration enum = request.getParameterNames();
   String parameterName = null;
   while(enum.hasMoreElements()) {
 parameterName = (String)enum.nextElement();
 if(parameterName.endsWith(".x")) {
   button = parameterName.substring(0,parameterName.indexOf('.'));
 }
   }
Sorry, I seem to have gotten a bit confused here. You are correct with your 
assumption that I meant the "property" attribute.

I described what I wanted to achieve in my original posting. To recap, I 
want to have a page with several delete buttons. Clicking on one button 
would produce parameter

delete_23.x=56
to be sent => we parse that, and delete item with ID 23 from database. 
Choosing a different delete -button would send parameter

delete_304.x=144
=> we delete item with ID 304.
I am aware that I can use the approach you suggested (parse request 
parameters manually), and have been doing that for ages before I started 
learning Struts :) I was just expecting that Struts would somehow help me 
with this task. I have been looking into indexed properties but I have not 
quite figured out how to properly implement this kind of functionality using 
them.

Struts Path problem

[Ding Lei]

Hello List,
I encountered problems on displaying images in JSP pages which
belongs to a specified Struts module.
   If we include an image file in a JSP page, say "A.jsp", and we
we define an action forward that points to it, and access through
that action forward in browser, the image is able to display correctly.
But if "A.jsp" contains an iframe which points two another JSP page
under the same module(through it's filename,not action forward), 
say B.jsp, then all images on B.jsp won't able to display properly.
  Similiarly, if there's some javascript code snippet on A.jsp which
popups something, such as a calender, all images on it won't able to
display.

  Any idea? Thanks!

May be the problem related to directory structure.

If the forward action to A.jsp has happened then A.jsp  should have

You should better call request.setCharacterEncoding() in

Request parameters are read when ActionServlet prepares form

difinition on my jsp page <%request.setcharacterEncoding("UTF-8");%>
   

I think you have no reason to put this call in your JSP.

hi
thank you for your post.
I test what you said , for creating a filter and apply it on web.xml , 
but still i could not get parameter in utf-8 and those are in ISO 
Latin-1 encoding , could you post the filter you mean here?
is it possible that WAS does not support UTF-8 parameter?
thank you

RE: Nested tags...

[Kataria, Satish]

I am not sure but just a guesss
You are not closing the html:form tag and a html:form can't be embeded
within another
Just closing the tags should solve the problem.

JSF-Struts integration

[Prasad, Kamakshya]

Hi All,

I have a bean containing ArrayList property as given below

public ArrayList getCountries() 
{ 
return arrlCountries; 
}
public void setCountries(int iIndex, String strCountry) 
{ 
if (arrlCountries == null)
{
arrlCountries = new ArrayList();
}
arrlCountries.add(strCountry); 
}

This property is displayed in the jsp by the following code







But when user changes the texts in textboxes and submit, the old values
comes up and not the new submitted one.

Please help me on this.

Also while putting logs I realized the get method is called twice after
form submission. Could anyone please help me find the reason for this?

Thanks and Regards,
KP

As I said in my previous message, the nightly builds of the
Struts-Faces integration library include two versions of the standard
Struts example application -- one with Tiles and one without.  Both of
them use the Struts validator framework in conjunction with page that
use JavaServer Faces components.  Your best bet is to examine the
sources in these two webapps to understand what is going on.

handling multiple independent window

[Kailash Vasani]

Hi,

Is it possible to have 2 windows showing same JSP page, but different data,
using struts?
The data to be displayed is populated in form bean, in action class.

Both the JSP pages would be performing same set of operations, but not
necessarily in same order.
Operations are Save, Update etc. When operation is performed, data from form
bean would be used
to perform database operation.

To best of my knowledge, form beans with session scope will fail to achieve
this, as both the windows
would be sharing the same instance of form bean. Request scoped form beans
are not feasible due to size
and complexity (nesting mainly) of data structure.

There is restriction that there may be only one user session in application.

Did any one faced similar situation? Do anyone have any suggestion?

with this task. I have been looking into indexed properties but I have not 
quite figured out how to properly implement this kind of functionality 
using them.
I finally figured out a reasonably satisfying way to do this while using 
Struts to help as much as possible:

public class ChoicesForm extends ActionForm {
private Collection choices;
private ImageButtonTracer deleteButton;
public void reset(ActionMapping arg0, HttpServletRequest arg1) {
this.choices = new ArrayList();
this.deleteButton = new ImageButtonTracer();
}
public ChoiceView getChoice(int index) {
// if struts tries to get item with id index,
// and it does not exist,
// add new items until ok.
while (choices.size() <= index) {
choices.add(new ChoiceView());
}
List lChoices = (List) choices;
return (ChoiceView) lChoices.get(index);
}
public Collection getChoices() {
return choices;
}
public void setChoices(Collection collection) {
choices = collection;
}
public ImageButtonTracer getDeleteButton() {
return deleteButton;
}
public void setDeleteButton(ImageButtonTracer tracer) {
deleteButton = tracer;
}
}
public class ImageButtonTracer {
private Map clickedButtons;
public ImageButtonTracer() {
clickedButtons = new HashMap();
}
public Button getItem(int index) {
Button toReturn = (Button) clickedButtons.get(new Integer(index));
if (toReturn == null) toReturn = new Button();
clickedButtons.put(new Integer(index), toReturn);
return toReturn;
}
public void setItem(int index, Button button) {
logger.debug("setItem(" + index + ")");
clickedButtons.put(new Integer(index), button);
}
public Collection getClickedButtonIndexes() {
return clickedButtons.keySet();
}
public class Button {
private int x;
private int y;
public int getX() { return x; }
public int getY() { return y; }
public void setX(int i) { x = i; }
public void setY(int i) { y = i; }
}
}
public class ChoiceView implements Serializable {
private String key;
private String name;
private String description;
... + getters & setters
}

 
 
   
 
 
 
 
   
 
 
 


public class SaveChoicesAction extends Action {
public ActionForward execute(
ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response)
throws Exception {
ChoicesForm cform = (ChoicesForm) form;
ChoiceDAO dao = new ChoiceDAO();
// UPDATE
Iterator i = cform.getChoices().iterator();
while (i.hasNext()) {
ChoiceView view = (ChoiceView) i.next();
Choice toUpdate = ChoiceView.createChoice(view);
dao.update(toUpdate);
}
  // DELETE
Collection deletedIds =
cform.getDeleteButton().getClickedButtonIndexes();
if (deletedIds != null) {
Iterator d = deletedIds.iterator();
while (d.hasNext()) {
int deleteIndex = ((Integer) d.next()).intValue();
ChoiceView toDelete = cform.getChoice(deleteIndex);
Choice choice = ChoiceView.createChoice(toDelete);
dao.delete(choice);
}
}
return mapping.findForward("success");
}
}
ImageButtonTracer can be simplified a bit if one assumes that only one 
button can be clicked per request (as is the case) => 	public Collection 
getClickedButtonIndexes()  can be changed to public int 
getClickedButtonIndex(). This works, and I can use indexed properties 
somewhat comfortably.

[OT] form default submit button

[Erez Efrati]

Hi,
 
This not a struts issue though my project is well attached down to the
bones to struts.
I am a bit rusty in HTML and I need your advice.
I have a login form with username and password fields. The button is
built with a table consisting of the graphical edges and the text 
(retrieved from the resource bundle) in the middle.
 
What do I have to do so when the user is in the username field or
password and hits  the form will submit. Currently it does not do
it and I have to click on the "table" button, whereas with buttons made
of . it worked automatically even with more
forms on the page where each works the same way autonomously. 
 
Here is the fragment of the button in my login form.

How to help the user navigate to his own folder

[Gao Jun]

Hi everyone,
 
I've a problem in using Slide and I'd like to hear your suggestion.
We are using slide to implement a document management system and we
will assign specific users access to specific folders. For example,
we have a doc tree like,
 
A
   -B1
-C
   -B2
 
One user has the access to folder C, so he can read and write in folder C.
However, I have the problem of letting this user enter C folder. 
First, because he doesn't have access to A and B1, so he can't navigate to
C by enter A first, then enter B1.
Second, if I let this user jump into C directly, this user should know his
folder has the path A/B1/C. But does Slide provide a way (some api) to let
us find this users all available paths?
 
Have you ever met this kind of problem? Any suggestion?
 
Thanks and regards,
 
Jun

Re:

[Erik Weber]

Not positive on this, but I think the place to set this default date 
string would be in your form bean's reset method. Then your JSP wouldn't 
need any code, the html:text field would pull the just-initialized value 
from the form bean, as reset would be invoked by Struts just before the 
JSP renders.

As far as I know, you should steer clear of using the "value" attribute 
to any HTML input tags. You won't get proper "memory" of what the user 
had entered when the page is redisplayed after a form validation error.

Someone correct me if that is not the right approach. It's what I do 
when I want checkboxes to be checked by default though, for example, so 
this seems analogous.

I just tried this in one of my forms. Works fine under both add and

As far as I know, you should steer clear of using the "value" 
attribute to any HTML input tags. You won't get proper "memory" of 
what the user had entered when the page is redisplayed after a form 
validation error.

Someone correct me if that is not the right approach. It's what I do 
when I want checkboxes to be checked by default though, for example, 
so this seems analogous.

Subject: Loosing request attributes


Hi,
when a user request hits the ActionForm's validate
method and bounces back, i'm loosing some request
attributes that i had set for the page. In other
words, if the user inputs some data that don't pass
the validate method,
the page comes back with a few request scope
attributes missing.

Is there a way to avoid that this happens?

Re: [OT] DAO ... where to draw the line?

[Matthew J. Vincent]

Hi all,
Thanks for the info.  Here's another issue.
What if I have an employee search screen that wants to show only some of 
the information of an employee (not all).  What do you do then? 

1. Instanatiate an Employee object and only fill in the relative 
information?  Keep in mind that this could be just employee name and 
location on the search results screen and then when the user chooses 
which employee to view I need to get all of the employee information.

2.  Instantiate an Employee object and fill out all the information even 
though you won't be needing most of it on the search results screen?

3.  Create 2 DTOs, one called Employee and one called EmployeeSearch 
DTO.  The EmployeeSearch DTO only stores what needs to be shown on the 
search results screen and the EmployeeDTO holds all the information for 
what needs to be shown on the detail screen?

4.  Something else...
Thanks!

hi matthew,
I wont say that you go with one or other of your approaches.
It depends upon type of assosciation that 2 entities may share. They 
may have aggregation or composition relationship. Depending on that 
your DAO implementation will decide that you need to get ONLY id or 
the composite objects.

Let me explain.
Say you have class named ORDER ad ORDER_DETAILS. (consists-of 
relationship) Order without order details is nothing. So you may get 
the OrderDetails object as well when you get Order.

Now say you have EMPLOYEE and DEPARTMENT. (has-a relationship) 
EMPLOYEE *may* still exists with or without department. So you may get 
only id of department and later fetch the department.

Think in employee table, you have relationship (reports-to). If you 
specify this relation as composition, you may go on fetching the 
objects all the way up to the organization chart ;-)

Do i make sense?

Subject: [OT] DAO ... where to draw the line?

[OFF TOPIC]
I know this is a struts forum, but as struts developers using DAOs, 
where do your DAO implementation draw the line?
For example:

Let''s say I have three tables:
Employee (contains employee_id, employee_name,  and dept_id)
Department (contains dept_id, dept_name, loc_id)
Location (contains loc_id, location_name)
How deep do your classes go to replicate the data?
Do you do this...
public class Employee {
   private int id;
   private String name;
   private int deptId;   // just the id
   // .. implementation details
}
or do you do this
public class Employee {
   private int id;
   private String name;
   private Department dept;  // all of the data
   // .. implementation details
}
and so on and so on.   Class Department has the same type of 
problem.  Does it hold just the id for location or a variable class 
Location?

Should DAOs just fill in the id (keys) so it is up to the application 
using the DAOs to get the Employee class, then the Department class, 
and the the Location class like:

Employee emp = EmployeDAO.getEmployee(1);
Department dept = DepartmentDAO.getDepartment(emp.getDeptId());
Location loc = LocationDAO.getLocation(dept.getLocId());
System.out.println(emp.getEmpName() + " works in " + 
loc.getLocationName());

or
Employee emp = EmployeDAO.getEmployee(1);
System.out.println(emp.getEmpName() + " works in " + 
emp.getDept().getLoc().getLocationName());

Now this is just a simple example, but where do you draw the line?  
It's possible to go on and on and on and cycle back to employee...

Any thoughts, links, tips, best practices, whatvere would be helpful!
Thanks!
Matt

Need help with layered Map iteration in JSP

[Erik Weber]

I could use some Struts-EL/JSTL tag help, please.
I have a Map with each entry having a String as the key and a bean array 
as the value.

I need two iterations, one nested inside the other.
For the outer iteration, I want to iterate the keySet of the Map. I 
don't know what the keys are going to be or how many there will be.

Within that iteration, for each key in the keySet, I need to iterate 
over the buckets of the array that is the value for that key.

To make this more clear, let's say I will produce a table of tables, 
somewhat like this:


 
 
 
   
 
   
   
   
 
 
   
   
   
   
 
 
   
   
 
   
 
 
 
 
   
 
   
   
   
 
 
   
   
   
   
 
 
   
   
 
   
 
 
 

Could someone show me some skeleton JSTL or Struts-el code?
I would appreciate it very much,
Erik

Re: Accessing bean properties problem

[Michael McGrady]

This is all "over-engineered", Janne.  I used to do something similar, 
however.  As I menteioned before, I just use the following code to 
determine which image was clicked:

   String imageClicked = null;
   Enumeration enum = request.getParameterNames();
   String parameterName = null;
   while(enum.hasMoreElements()) {
 parameterName = (String)enum.nextElement();
 if(parameterName.endsWith(".x")) {
   imageClicked = 
parameterName.substring(0,parameterName.indexOf('.'));
 }
   }
   return imageClicked;

That's all there is to it.  Your button solution is too complicated in 
any event.  The better button solution involves making only one button 
and then nuking that button as soon as you determine what image was 
clicked.  I just nuked the whole solution, since it is unnecessary.

ImageButtonTracer can be simplified a bit if one assumes that only one

Collection getClickedButtonIndexes()  can be changed to public int 
getClickedButtonIndex(). This works, and I can use indexed properties 
somewhat comfortably.

Any improvements / alternatives are welcome.

All the solutions involve parsing the request parameters, Janne.  That

difference is that there is a clear, extensible, light, fast, loosely

If you were using the solution I have suggested for "ages", you should 
go back to it.  Your present solution is horrible in comparison.  That

There are two problems, first, your solution does not solve my case. Note 
that this is not a simple case of distinguishing whether "accept" or "nuke" 
was clicked (for those I would not certainly have used the original strategy 
from the wiki page, I agree with over-engineering there) - I want to get the 
ID conveniently as well. Please refer to earlier posts for details. Of 
course, I can add more parsing code to get also the ID, but this does not 
help with the second problem.

Which is: the purpose of Struts is to help me with some tasks, one important 
being parsing HttpServletRequest parameters so I do not have to deal with 
them manually. This service comes with a price - I have to spend time to 
learn the principles of the framework and all the small annoying quirks and 
unintuitive details (so far I've ran into quite a few!). If I have to both 
learn to cope with Struts and still continue to parse request parameters 
manually like I have done so many times before, the deal does not sound so 
good to me. The solution you suggest works, is not too complicated, but it 
does not integrate as seamlessly with the rest of the framework and how it 
is used to handle parameters. Button parameters end up being an exception to 
the general rule and I prefer a "pretty" solution. The solution I described 
also integrates nicely to the way other indexed properties are handled on 
the JSP page.

I don't know, but I am currently satisfied with the solution I am using. I 
end up creating one additional class (ImageButtonTracer) and add instance of 
it as a field to each form that requires this kind of "indexed buttons". You 
would probably create one additional helper class (with a further developed 
version of the method you present) and add parameter name encoding logic to 
each form that contains such buttons.

This is all "over-engineered", Janne.  I used to do something similar, 
however.  As I menteioned before, I just use the following code to 
determine which image was clicked:

   String imageClicked = null;
   Enumeration enum = request.getParameterNames();
   String parameterName = null;
   while(enum.hasMoreElements()) {
 parameterName = (String)enum.nextElement();
 if(parameterName.endsWith(".x")) {
   imageClicked = 
parameterName.substring(0,parameterName.indexOf('.'));
 }
   }
   return imageClicked;

That's all there is to it.  Your button solution is too complicated in any 
event.  The better button solution involves making only one button and then 
nuking that button as soon as you determine what image was clicked.  I just 
nuked the whole solution, since it is unnecessary.

All the solutions involve parsing the request parameters, Janne.  That is 
clearly the only way you will ever know what they are.  The difference is 
that there is a clear, extensible, light, fast, loosely coupled, solution 
and a messy, solution specific, heavy, slow, tightly coupled version of the 
solution.  You are seeking the latter for some reason.  There is NO reason 
to couple your solution to Struts.  Struts is a framework and is not meant 
to be a fulcrum to solve this problem.  If you were using the solution I 
have suggested for "ages", you should go back to it.  Your present solution 
is horrible in comparison.  That is just plain true.
If you use Struts to do your HTTP request processing, you'll couple your 
HTTP request processing to Struts. I don't know what all this nonsense about 
"decoupling from Struts" is meant to be. That is the whole point of using 
Struts, there is absolutely no logic in trying to decouple you application's 
HTTP parameter handling from Struts. It is what Struts does.

You seem to like parsing HttpServletRequests manually, so why don't you skip 
Struts altogether and parse all request parameters manually? I bet it would 
be "clear, extensible, light, fast, loosely coupled solution". Hell, who 
needs ActionForms after all? They make your solution tightly coupled to 
Struts!

Ravi, without getting real complicated, I use PlugIns to do this!
Implement org.apache.struts.action.PlugIn. You only need to write two 
methods -- init and destroy. In your init method, gather some data store 
it as application scope attributes (you get a reference to the 
controller Servlet in the init method). Finally, register your PlugIn 
with struts-config.xml. When your Struts app initializes, your PlugIn's 
init method is invoked. Your JSPs now have easy access to the cached 
data, as do your Actions.

Validating indexed properties

[Bill Siggelkow]

I posted this message to the commons-user list but didn't receive any 
feedback. Basically, I am trying to get the indexedListProperty feature 
of Validator to allow me to report errors correctly for each property on 
a form that fails validation -- the only way I could get it to work was 
to change the Validator Field class -- I am trying to find out if there 
are any other known work arounds.
===
I have been working with indexedListProperty in Struts 1.2 (using 
Validator 1.1.3, I believe). Suppose I have the following validation:



   
   
   
   minlength
   5
   


Now, when I validate the form, if the minlength validation fails on one 
of the indexed properties, then none of the rest of the partNumber 
fields are checked for minlength.

I am using Struts and I was trying to output the error message beside 
the property using html:messages -- the result is that the error message 
is only generated for the first property that fails.

For what its worth, I did hack a fix -- I changed the
ValidatorResults validate(Map params, Map actions) method in the Field 
class [org.apache.commons.validator.Field].

Basically where it had (on line 724):
-
if (!good) {
return allResults;
}

I made it ...
-
if (!good && numberOfFieldsToValidate <= 1) {
return allResults;
}

This worked -- in other words I get all the messages generated for each 
field if the field is indexed.

Any opinions on ramifications of making this change or other possible 
solutions? I have not messed at all with the client-side javascript so I 
am not sure what the behavior is like there.

Hi everyone,
 
I've a problem in using Slide and I'd like to hear your suggestion.
We are using slide to implement a document management system and we
will assign specific users access to specific folders. For example,
we have a doc tree like,
 
A
   -B1
-C
   -B2
 
One user has the access to folder C, so he can read and write in folder C.
However, I have the problem of letting this user enter C folder. 
First, because he doesn't have access to A and B1, so he can't navigate to
C by enter A first, then enter B1.
Second, if I let this user jump into C directly, this user should know his
folder has the path A/B1/C. But does Slide provide a way (some api) to let
us find this users all available paths?
 
Have you ever met this kind of problem? Any suggestion?

RE: Caching Framework

You could use Providers (http://providers.sourceforge.net) to handle collections
of objects, cache them and in addition use these collection to populate
select tags, create dependant drop down lists and display labels (descriptions)
according to an ID (i.e using  tag similar to  Struts )

With providers you can create collections with different strategies (fixed,
JDBC, filtered, etc) and optionally you could create your own collection
factory.

Cheers.
Guillermo.

No mas, Janne!  If you think that your serpentine code is superior to 
the following:

public class ButtonMiner {
 public int getId(HttpServletRequest request) {
   String buttonValue = null;
   Enumeration enum = request.getParameterNames();
   String parameterName = null;
   while(enum.hasMoreElements()) {
 parameterName = (String)enum.nextElement();

 return Integer.parseInt(buttonValue.substring(1));

which you could get from indexing "_", then go for it!  I have no more

quirks and unintuitive details (so far I've ran into quite a few!). If I 
have to both learn to cope with Struts and still continue to parse request 
parameters manually like I have done so many times before, the deal does 
not sound so good to me. The solution you suggest works, is not too 
complicated, but it does not integrate as seamlessly with the rest of the 
framework and how it is used to handle parameters. Button parameters end 
up being an exception to the general rule and I prefer a "pretty" 
solution. The solution I described also integrates nicely to the way other 
indexed properties are handled on the JSP page.

I don't know, but I am currently satisfied with the solution I am using. I 
end up creating one additional class (ImageButtonTracer) and add instance 
of it as a field to each form that requires this kind of "indexed 
buttons". You would probably create one additional helper class (with a 
further developed version of the method you present) and add parameter 
name encoding logic to each form that contains such buttons.

This is all "over-engineered", Janne.  I used to do something similar, 
however.  As I menteioned before, I just use the following code to 
determine which image was clicked:

   String imageClicked = null;
   Enumeration enum = request.getParameterNames();
   String parameterName = null;
   while(enum.hasMoreElements()) {
 parameterName = (String)enum.nextElement();
 if(parameterName.endsWith(".x")) {
   imageClicked = 
parameterName.substring(0,parameterName.indexOf('.'));
 }
   }
   return imageClicked;

That's all there is to it.  Your button solution is too complicated in 
any event.  The better button solution involves making only one button 
and then nuking that button as soon as you determine what image was 
clicked.  I just nuked the whole solution, since it is unnecessary.

Ravi, without getting real complicated, I use PlugIns to do this!

Implement org.apache.struts.action.PlugIn. You only need to write two

methods -- init and destroy. In your init method, gather some data store

it as application scope attributes (you get a reference to the

controller Servlet in the init method). Finally, register your PlugIn

with struts-config.xml. When your Struts app initializes, your PlugIn's

init method is invoked. Your JSPs now have easy access to the cached

data, as do your Actions.

Re: Accessing bean properties problem

[Michael McGrady]

I guess, to be more concilliatory, Janne, I could say that if you want 
to use your solution, then you could just index item, e.g. 

public Id getIndex(Integer id) {
 return new Id(intValue());
}
Where the class Id is the following:
public class Id {
 private int id;
 public Id(Integer x) {
   id = x.intValue();
 }
 public int getId() {
   return id;
 }
 public void setX(Integer x) {
 }
 public void setY(Integer y) {
 }
}
That gets rid of all your classes and gives you the same result.

In Struts, a layered framework, caching data should happen in the data

Caching data in View layer is not Strut-y.

import org.apache.struts.action.ActionServlet;

public class Cacheimplements PlugIn

   put your code in here to fire off any caching of data
   }

  public void destroy()

 any cleanup code.

Add the following into your Struts-config.xml file





Parameters can be supplied to the class using the

Hope this helps.

The forms are meant to mine values.  They are not meant to supplant 
business logic.  The question is not about "manual" parsing.  The 
question is when and how to parse.  Parsing is parsing -- is "manual" of 
necessity.   There is a difference between "manual" and "hard coding". 

ActionForms are not tightly coupled to Struts.  They are Struts.  I for 
one am a great advocate of Struts and believe in fact that in the end it 
will be preferred to JSF by a long shot.  Still, loose coupling is a 
primary goal of Struts, not the opposite.  I am not sure why you prefer 
your solution.  I cannot see a single advantage in practice to it.  But, 
as I said, c'est la vie!

Re: Loosing request attributes

[Erik Weber]

You shouldn't have to do anything (in general, you rarely need to 
implement reset) special for this. Struts does this for you. The user 
submits the form. The form bean is populated with the user's input. 
Validation starts on the form bean. Validation fails. Struts forwards 
back to the input page, and the struts tags render all the values that 
the user had input using the populated form bean.

Could you describe in more detail which types of form values seem to be 
"missing" and which ones are intact? Is there a pattern to it?

Subject: Re: Loosing request attributes
I was taking a look at the HttpServeltRequest and
ServletRequest apis and noted that theres a method
"getParameterMap()" wich returns a map of the
parameters, BUT there isn`t such a

method.
So, what`s an automated way to re-set all my

Re: Need help with layered Map iteration in JSP

How can I refer to the index of the current iteration with c:forEach

I could use some Struts-EL/JSTL tag help, please.
I have a Map with each entry having a String as the key and a bean array 
as the value.

I need two iterations, one nested inside the other.
For the outer iteration, I want to iterate the keySet of the Map. I 
don't know what the keys are going to be or how many there will be.

Within that iteration, for each key in the keySet, I need to iterate 
over the buckets of the array that is the value for that key.

To make this more clear, let's say I will produce a table of tables, 
somewhat like this:


 
 
 
   
 
   
   
   
 
 
   
   
   
   
 
 
   
   
 
   
 
 
 
 
   
 
   
   
   
 
 
   
   
   
   
 
 
   
   
 
   
 
 
 

Could someone show me some skeleton JSTL or Struts-el code?
I would appreciate it very much,
Erik

Re: Need help with layered Map iteration in JSP

[Kris Schneider]

 supports a "varStatus" attribute. The value of that atrribute is a
String that names an instance of javax.servlet.jsp.jstl.core.LoopTagStatus. The
LoopTagStatus instance has nested visibility so that it's only available within
the enclosing  tag. LoopTagStatus exposes a number of properties,
but the one you're probably interested in is "index":

..
  
<%-- ${status.index} is the current index --%>
...
  
..

Read only iterate?

[Mike Elliott]

I've been totally defeated in my attempt to alter an html:text
element inside a logic:iterate tag.  There must be a way to
accomplish this, but I've been beating my head against the wall
for three days now without making progress.

I have simplified the problem substantially from the initial page.
What I have now looks like this:

   -
  [ Submit ]
   Problematic Input [0   ]
   Problematic Input [1   ]
   Functioning Input [A Value ]
   -

The lines containing "Problematic Input" were generated by a
logic:iterate tag, which successfully fetched the list of objects from
the form bean.  The last line, containing "Functioning Input", was
generated outside of the logic:iterate tag.  Actual contents of the
jsp page, bean, etc., are attached.

What happens at runtime is that when the JSP page is rendered, the
text fields for all three rows are successfully and correctly fetched
from the form bean, but only the last row can be changed.  As the log
shows:


  INFO  [org.apache.struts.util.PropertyMessageResources] Initializing, 
config='org.apache.struts.taglib.html.LocalStrings', returnNull=true
  INFO  [problem.ProblemBean] initializing entries
  INFO  [problem.ProblemBean$ProblemItem] setInteger_value to 0
  INFO  [problem.ProblemBean$ProblemItem] setInteger_value to 1
  INFO  [problem.ProblemAction] show
  INFO  [org.apache.struts.util.PropertyMessageResources] Initializing, 
config='org.apache.struts.taglib.logic.LocalStrings', returnNull=true
  INFO  [problem.ProblemBean] getEntries
  INFO  [problem.ProblemBean$ProblemItem] getInteger_value
  INFO  [problem.ProblemBean$ProblemItem] getInteger_value
  INFO  [problem.ProblemBean] getWorking_perfectly

  INFO  [problem.ProblemBean] setWorking_perfectly to 'mutated'
  INFO  [problem.ProblemAction] update
  INFO  [problem.ProblemBean] getEntries
  INFO  [problem.ProblemBean$ProblemItem] getInteger_value
  INFO  [problem.ProblemBean$ProblemItem] getInteger_value
  INFO  [problem.ProblemBean] getWorking_perfectly

The page is initialized properly.  All three values are fetched from
the form bean via the expected get methods.  The html form is properly
populated and displays the expected values (0, 1, and "A Value").

The three fields are then changed (to 5, 5, and "mutated") and the
submit button is selected at the point in the log file where I have
inserted the  annotation.

This causes the form to be submitted to the Action, causing the set
method for the field "working_perfectly" to be invoked (as it should
be), but the set method for the two fields in the logic:iterate tag is
not invoked.  And I don't know why.  And I can't seem to get them to
be invoked, either.

So . . . the magic isn't working.  Something must be needed to tell
the generated servlet not to treat these two properties (inside the
logic:iterate tag) as read-only.  What should it be?  How can I get
these properties to be updated in the form bean as the
"working_perfectly" property is?

Like I said -- I've been beating my head against this problem for
three days now.  There's just got to be a way!

I'm guessing that a List won't work and you need to have an array.

Lists work, but you have to write your own set(int index) method to set the 
correct object from the List.

Spring's MVC? (was Re: Spring/Struts & Hibernate)

[dhay]

Talking of Spring, has anyone tried out their MVC framework (hopefully this
isn't considered sacrilege!!).

Any comparisons with Struts?

cheers,

Apparently you have forgotten our discussion a few days ago.  I have
implemented a BeanMapForm which you said the nightlies would allow me to
use, since they no longer read org.apache as org.getApache().  The
BeanMapForm is at
http://wiki.apache.org/struts/StrutsCatalogInstrumentableForms.  I was
asking what I needed to do that.

Re: [OT] DAO ... where to draw the line?

Hi all,
Thanks for the info.  Here's another issue.
What if I have an employee search screen that wants to show only some 
of the information of an employee (not all).  What do you do then?
1. Instanatiate an Employee object and only fill in the relative 
information?  Keep in mind that this could be just employee name and 
location on the search results screen and then when the user chooses 
which employee to view I need to get all of the employee information.

2.  Instantiate an Employee object and fill out all the information 
even though you won't be needing most of it on the search results screen?

3.  Create 2 DTOs, one called Employee and one called EmployeeSearch 
DTO.  The EmployeeSearch DTO only stores what needs to be shown on the 
search results screen and the EmployeeDTO holds all the information 
for what needs to be shown on the detail screen?

4.  Something else...
Thanks!

hi matthew,
I wont say that you go with one or other of your approaches.
It depends upon type of assosciation that 2 entities may share. They 
may have aggregation or composition relationship. Depending on that 
your DAO implementation will decide that you need to get ONLY id or 
the composite objects.

Let me explain.
Say you have class named ORDER ad ORDER_DETAILS. (consists-of 
relationship) Order without order details is nothing. So you may get 
the OrderDetails object as well when you get Order.

Now say you have EMPLOYEE and DEPARTMENT. (has-a relationship) 
EMPLOYEE *may* still exists with or without department. So you may 
get only id of department and later fetch the department.

Think in employee table, you have relationship (reports-to). If you 
specify this relation as composition, you may go on fetching the 
objects all the way up to the organization chart ;-)

Do i make sense?

Subject: [OT] DAO ... where to draw the line?

[OFF TOPIC]
I know this is a struts forum, but as struts developers using DAOs, 
where do your DAO implementation draw the line?
For example:

Let''s say I have three tables:
Employee (contains employee_id, employee_name,  and dept_id)
Department (contains dept_id, dept_name, loc_id)
Location (contains loc_id, location_name)
How deep do your classes go to replicate the data?
Do you do this...
public class Employee {
   private int id;
   private String name;
   private int deptId;   // just the id
   // .. implementation details
}
or do you do this
public class Employee {
   private int id;
   private String name;
   private Department dept;  // all of the data
   // .. implementation details
}
and so on and so on.   Class Department has the same type of 
problem.  Does it hold just the id for location or a variable class 
Location?

Should DAOs just fill in the id (keys) so it is up to the 
application using the DAOs to get the Employee class, then the 
Department class, and the the Location class like:

Employee emp = EmployeDAO.getEmployee(1);
Department dept = DepartmentDAO.getDepartment(emp.getDeptId());
Location loc = LocationDAO.getLocation(dept.getLocId());
System.out.println(emp.getEmpName() + " works in " + 
loc.getLocationName());

or
Employee emp = EmployeDAO.getEmployee(1);
System.out.println(emp.getEmpName() + " works in " + 
emp.getDept().getLoc().getLocationName());

Now this is just a simple example, but where do you draw the line?  
It's possible to go on and on and on and cycle back to employee...

Any thoughts, links, tips, best practices, whatvere would be helpful!
Thanks!
Matt

Missing, as in the when the screen gets re-rendered they're missing or the data is 
missing?
If the data is missing are you using primitives in your action form or Strings?  
If you're using primitives then of course your data is misssing.  See archives and 
documentation for why.

RE: Loosing request attributes

Sorry Kataria,
the redirect attribute is inside the forward tag. My
fault.
Any way, i'm not using and as i understand the default
is false.

RE: Loosing request attributes

[Leandro Melo]

As i replied many times for this topic, i'd like to
expose the situation again and in DETAILS.

Suppose a user submits a request that is handled by
MyActionDoSomething. Then this action sets a request
attribute like this:

request.setAttribute("MyObject", obj); 

and forwards the request to the page
myPageDoSomeOtherThing.jsp, wich has some inputs for
the user to fill in.
This page (myPageDoSomeOtherThing.jsp) uses the bean
"obj" that was set in MyActionDoSomething.java ok !?

Now suppose the user submits wrong information in
myPageDoSomeOtherThing.jsp, what will cause the
validate method in the associated ActionForm to return
some ActionErrors. BUT when the ActionForm send this
page back for the user to re-input data, the bean
"obj" that was set at the very beginning in
MyActionDoSomething.java is NOT present anymore!

I think now it's clear that i'm not talking about the
formBean attributes, right !?

RE: Loosing request attributes

[Hubert Rabago]

This is because when the user submits the form, that already starts a
different request, so the request attributes are no longer there.
In your mapping for the action where the form gets submitted to, where does
the input attribute point to?

Do you 

RE: Losing request attributes

You can point the "input" to an action which will populate the request with
the attribute(s) you need, and then forwards to your form.

Javascript question re: dynamically generated input type='text' controls

[Christina Siena]

Hi,

I am developing a page containing dynamically generated input
type="text" controls where their names consist of multiple composite
keys. The name of the input type="text" controls, however, can not be
referenced correctly using javascript. For example, I have the
following html input tag:



The following javascript won't work because the control name contains =
and ; and : as follows:

document.formname.number=1480;countryCode=USA;templateNumber=7;typeCode=STAGE;languageCode=EN;idTypeCode=MODE:.value
= "";

I only have one other idea how to solve this problem. Instead of control
names containing the multiple composite keys, instead use a simple valid
name. In the action, map the valid name to the multiple composite keys.
Does
anyone have any other ideas how to solve this?

Thanks in advance.

Re: Losing request attributes

[Denis Avdic]

In order to keep the actual entries that the user typed in (so they
don't have to retype everything if they changed a bunch of things) I
usually put the entire form and errors into request if there are
errors.

Then you need to make sure that your  populate action checks for
presence of the form in request and overrides the DB entries with the
ones in the form.

Re: Losing request attributes

Denis, that's not the point of our discussion. One
more time: I'm not talking about formBean attributes.

Anyway, Hubert pointed a workaroung for my problem.

Displaying bean values within tiles

[Andy Engle]

Hi all,

I hate to ask a real, boring, non-OT question on a Friday, but I am
working with a Struts application in which I am using tiles to organize
my views.  What I want to be able to do is pass in a bean with a String
(or, "string beans" for all you farmer types out there) into my tiles
setup and have that value displayed in my view.

I have my tiles definitions in tiles-defs.xml, and of course I have a
file template.jsp which handles my layout.

I have horsed around with using the  tag with the
String value, but I can't seem to get that to work -- for the page I
want to display it on, it either displays the default value for the
page as I have it set in tiles-defs.xml, or it doesn't print anything
at all.  I suppose my question could/should be how and where would I
use this useAttribute tag, as it seems to be the solution to my
problem.

Thanks for your help, and I look forward to receiving your responses.


Best Regards,
Andy

Re: Loosing request attributes

[Leandro Melo]

Erik,
i'm not talking about form attributes, that's what i
said in my last e-mail.
I'll try to clear it out.
Suppose a user submits a request that is handled by
MyActionDoSomething. Then this action sets a request
attribute like this:

request.setAttribute("MyObject", obj); 

and forwards the request to the page
myPageDoSomeOtherThing.jsp, wich has some inputs for
the user to fill in.
This page (myPageDoSomeOtherThing.jsp) uses the bean
"obj" that was set in MyActionDoSomething.java ok !?

Now suppose the user submits wrong information in
myPageDoSomeOtherThing.jsp, what will cause the
validate method in the associated ActionForm to return
some ActionErrors. BUT when the ActionForm send this
page back for the user to re-input data, the bean
"obj" that was set at the very beginning in
MyActionDoSomething.java is NOT present anymore!

I think now it's clear that i'm not talking about the
formBean attributes, right !?

Who calls the validate method ???

[Leandro Melo]

Hi,
could anyone tell me who calls the validate method of
the ActionForms?

I thought it was ActionServlet, but it seems not be
it.

Re: Who calls the validate method ???

[Hubert Rabago]

It's actually the RequestProcessor.
There's a processValidate() there where the form's validate() method is
called.

useAttribute:
 Declare a Java variable, and an attribute in the specified scope, using tile 
attribute value.
Java variable and attribute will have the name specified by 'id', or the original name 
if not specified. 

So I believe for tiles def:








In the jsp page:


Will allow



And yes, for this example I could have used .  :)

Not sure what you mean by pass in a bean to your tiles setup though.

The problem you are describing comes up a lot on this list - when 
validation fails and you are back on the initial form you will not have 
access to the previous set request attributes. It is for this reason 
that I now rarely ever set my mapping validate to "true" and instead 
call validate() from my Action after the form submits. The reason for 
this is when validation fails (ActionErrors/Messages return) I can then 
call a private setUp() method in my Action that is used to set up my 
form with any other request attributes that should always be there.

For example, a common complaint is: "I have a List that I set up in 
request scope that is used on the form for the user to select an item, 
but when validation fails this List will not be there." To get around 
this problem, simply call validate() manually in your action and if 
errors return you can then call a setUp() method that will repopulate 
what you need to be in the request, otherwise you just proceed on as 
normal.

I think "you" should:) I find it's often more beneficial to not rely on 
Struts calling this validate() method and instead you should call this 
manually.

From my other post:
 - when validation fails and you are back on the initial form you 
will not have access to the previous set request attributes. It is for 
this reason that I now rarely ever set my mapping validate to "true" and 
instead call validate() from my Action after the form submits. The 
reason for this is when validation fails (ActionErrors/Messages return) 
I can then call a private setUp() method in my Action that is used to 
set up my form with any other request attributes that should always be 
there.

For example, a common complaint is: "I have a List that I set up in 
request scope that is used on the form for the user to select an item, 
but when validation fails this List will not be there." To get around 
this problem, simply call validate() manually in your action and if 
errors return you can then call a setUp() method that will repopulate 
what you need to be in the request, otherwise you just proceed on as normal.

I'm curious why using the input parameter doesn't work for you?

See, I disagree with this entirely.  Pick lists can be put into application scope, if 
they are small enough.  Use the Fast Lane Reader pattern if they aren't.  If you need 
to customize the list based on whatever, then you can that through the list bean ( I 
wouldn't recommend just putting a list in application scope, rather a bean containing 
a list to support this kind of setup) and then set the input parameter.  If they 
aren't application in scope, then put them into the session.
I know that some people don't like putting things into session/application scopes 
because of memory.. however memory is not only cheaper then developer time, it's 
expensable too!

Indeed ... the feature is working as it was designed, based on
application user expectations that, if errors occur, whatever they
typed in is redisplayed (even if it is wrong) so that it can be
corrected.  That's the way that any rich GUI client works, and nobody
wants to use apps that force you to fill an entire form in again
simply because you made one mistake.

include vs. forward attributes in struts-config action element

[Michael Finger]

Hi all, 

I'm a bit puzzled about the processing of includes and forward
attributes in the struts-config action element vs. the forward element
under the action element

 

I understand why the forward element is there (and I use it quite a lot
, too) but I got a bit confused when I was looking around in the
RequestProcessor.process method:

 

public void process(HttpServletRequest request,

HttpServletResponse response)

throws IOException, ServletException {

 

...

 

// Process a forward or include specified by this mapping

if (!processForward(request, response, mapping)) {

return;

}

if (!processInclude(request, response, mapping)) {

return;

}

 





// Process the returned ActionForward instance

processForwardConfig(request, response, forward);

 

}

 

It looks to me like including a forward attribute  in the action element
will break any forwards you want with a forward element as it calls
RequestDispatcher.forward - which forwards on the output stream, etc...

This question came up when I was digging up info on  RequestDispatcher
forward vs. include and found refrences to these attributes, but no real
examples.   Does struts still support the forward and include attributes
as a legacy or a servlet api spec thing? Or what? 

 

 

Thanks

 

Michael Finger

Re: Who calls the validate method ???

[Leandro Melo]

Rick,
as i said i really like your approach, but there are
some input pages that are really really simple, so
there's no need for doing this.
Then, in this cases, i'd like to call some other
method just after validate is called from Struts.
That's why i was wondering "who" calls it.

If I try to use hidden fields to associate the valid name with the

by way of example:






Then put the key together in your action class.  HTML is not designed to do what you 
want to do.
