common-digester.jar conflict when usings Struts with Jasper Reports
Hi I am working on a web application with Struts and Jasper Reports. Jasper Reports requires common-digester.1.7.jar ( that is a latest version of struts's common-digester.jar), when i use this file, i get the following exceptions javax.servlet.jsp.JspException: Cannot find ActionMappings or ActionFormBeans collection at org.apache.struts.taglib.html.FormTag.lookup (FormTag.java:798) at org.apache.struts.taglib.html.FormTag.doStartTag (FormTag.java:506) at _index._jspService(_index.java:53) If i use common-digester.jar (struts version, older one)..then my Jasper Reports throws following exception.. java.lang.NoClassDefFoundError: org/apache/commons/digester/SetNestedPropertiesRule at net.sf.jasperreports.engine.xml.JRXmlLoader.load(JRXmlLoader.java:200) at net.sf.jasperreports.engine.xml.JRXmlLoader.load(JRXmlLoader.java:165) at net.sf.jasperreports.engine.xml.JRXmlLoader.load(JRXmlLoader.java:149) at com.netsol.pms.reports.ReportManager.buildReport(ReportManager.java:210) at com.netsol.pms.reports.ReportManager.getPreview (ReportManager.java:184) Please suggest me how can i resolve this conflict.. thanks & Regards Kashif Inam - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: ValidWhen and string comparison
Niall Pemberton a écrit : What you have should work - but its always going to give an error unless statut is set to "Doctorant". Yes! It's what i want. Are you sure "statut" is in your bean and getting populated? Yes, because when the error happen (every time with any "statut" value) i display errors () and the same form with the values the user entered. And the value of statut is what the user gave. Acording to me, that means that the form bean (and "statut") is populated with the user values. If i suppress the validwhen rule, the action is able to get the "statut" value.

Re: ValidWhen and string comparison
My problem is fixed! It was a stupid mistake. Excuse me for disturbing the list but the discussion opened my eyes. The type of statut was String[] and not String :-[ . So, I have a brand new question: how to valid "financement" when one of the value of "statut" is set to "Doctorant"? Is validwhen powerfull enough to do that? Thanx, Manu.

prepopulating jsp page
Hi, I am trying to pre-populate my JSP page with the values returned from the database when a user edits a client. I have just recently upgraded to Struts download 1.2.4. This is what I did before which worked: In my action class I created the form then populated it with the values from the DB. CreateClientForm updateForm = new CreateClientForm(); My struts config sent the response to the jsp page where I displayed the values as follows However in this new download the html tag library does not have a tag for name. Thus I cannot add the name tag to the html:form tag. So my jsp now looks ike this: and my struts config.xml : Can anyone please advise what I need to do to get these values into the jsp page as it appears empty. How do I get around this name tag? Thanks

Re: Debugging
Hi Bryon,
I had used once log4j with Tomcat server.
You can give absolute path for log file in log4j.properties.. like
log4j.appender.struts.File=d:/MyApplicationLogs/struts.log
so atleast you don't need to find log file .

RE: prepopulating jsp page
In your struts-config.xml, add a
section
Then in your action,
if (form != null)
{
localvariable = (CreateClientForm)form
}
now you can build your form bean properties as localvariable.set metods.

I cannot do the following CreateClientForm updateForm = (CreateClientForm)actionForm; Because the action is called from a search page and has a different form coming in. Thus when I try to reassign it I get a class cast exception. I also tried the first way you mentioned, but that did not populate the form either. -Original Message- From: Ekberg Mats KONSULT [mailto:[EMAIL PROTECTED] Sent: 29 September 2005 10:46 To: 'Struts Users Mailing List' Subject: SV: prepopulating jsp page I seen to be very fast and erronous today, try this: public ActionForward execute( ActionMapping actionMapping, AtionForm actionForm, HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse) throws Exception CreateClientForm updateForm = (CreateClientForm)actionForm; // populate the bean here updateForm.setXXX( ); updateForm.setYYY( ); > -Ursprungligt meddelande- > Från: Ekberg Mats KONSULT [mailto:[EMAIL PROTECTED] > Skickat: den 29 september 2005 11:41 > Till: 'Struts Users Mailing List' > Ämne: SV: prepopulating jsp page > > > > > -Ursprungligt meddelande- > > Från: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] > > Skickat: den 29 september 2005 11:38 > > Till: user@struts.apache.org > > Ämne: RE: prepopulating jsp page > > > > Do this in your action: > > > >CreateClientForm updateForm = new CreateClientForm(); > >// populate the bean here > > > >// then > >form = updateForm; > > > > When you say > > > > form = updateForm; > > > > what is my variable form of type? > > Form is the variable you got in your actions execute method: > > public ActionForward execute(ActionMapping actionMapping, > ActionForm > actionForm, HttpServletRequest httpServletRequest, HttpServletResponse > httpServletResponse) throws Exception > > > > > > > > > > > > -Original Message- > > From: Ekberg Mats KONSULT > [mailto:[EMAIL PROTECTED] > > Sent: 29 September 2005 10:34 > > To: 'Struts Users Mailing List' > > Subject: SV: prepopulating jsp page > > > > > > > > > -Ursprungligt meddelande- > > > Från: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] > > > Skickat: den 29 september 2005 11:26 > > > Till: user@struts.apache.org > > > Ämne: prepopulating jsp page > > > > > > Hi, > > > > > > I am trying to pre-populate my JSP page with the values > > returned from > > > the database when a user edits a client.

RE: prepopulating jsp page
Again doing this I think will throw a class cast exception.
localvariable = (CreateClientForm)form
I already have the form beans elements in my config.xml

My struts config sent the response to the jsp page where I displayed the
values as follows
However in this new download the html tag library does not have a tag
for name. Thus I cannot add the name tag to the html:form tag.
So my jsp now looks ike this:
and my struts config.xml :
Can anyone please advise what I need to do to get these values into the
jsp page as it appears empty. How do I get around this name tag?
Thanks

Re: prepopulating jsp page
It seems I need to reformulate my answer.
You need to CREATE a form with data for your NEXT page for populating
the fields.
You can't retrieve the form from the actionForm parameter of the action.
So you create in the execute function a form like this :
CreateClientForm updateForm = new CreateClientForm();
updateForm.setClientName(...); // bla bla bla
and
request.getSession().setAttribute("createClientForm", updateForm);
normally, it works,

RE: prepopulating jsp page
Yes, the flow is like this: My struts config has this action for the search page: This sends the actionclientForm to the actionclientaction class. This class goes to the db gets the information then forwards to editClient.jsp which has the action mapped: > > > type="com.medina.web.action.UpdateClientAction" > > > > name="createClientForm" > > > > scope="session" So when I tried to re cast it it threw a class cast because I was trying to cast actionClientForm to createClientForm. The bean named createCleintForm is of class createClientForm which is mapped in the form beans of config.xml. Does the same still apply?

RequestProcessor problem?
Hi all
I have problem with RequestProcessor. I added this statement to
struts-config.xml:
where CustomRequestProcessor is:
//--
public class CustomRequestProcessor extends RequestProcessor {
protected ActionForward processActionPerform(HttpServletRequest
request,HttpServletResponse response, Action action, ActionForm form,
ActionMapping mapping)
throws IOException, ServletException {
HttpSession session = request.getSession( );
User user = (User) session.getAttribute("user");
if (user == null) {
return mapping.findForward("stronaglowna");
} else {
return super.processActionPerform(request, response, action, form, mapping);
}
}
}
//-
in my project I use TILES
Problem: I got this error:
SEVERE: Servlet /RekrutApplication threw load() exception

SV: prepopulating jsp page
Your original question was on how to survive without the name-attribute in the tag. The answer is that the later versions of taglib/struts dont allow you to use the same Action-class on different ActionForms by changing the name-attribute (since it has been removed).

Form Bean Question
Hello: I have a question about how to setup a "situation" I have. I want to have a jsp page that has a variable number of text fields on it, named qty1, qty2, ... qtyN where N is some unknown number. I tried to set it up and use no form bean at all so I could just pull them from the request object in my action. So my question is, can I use struts without a form bean? And if I can't what do I have to do so I can handle situations like this? Thanks troy - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Form Bean Question
You could write lots of jsp code to handle it: As you can imagine this is pretty silly. In your action form, when preparing the display (ie when you put the text fields into the request scope) instead of adding them as separate entries it would be better to create a collection (eg ArrayList is good), add each string value to this collection, and then add this single collection to the request scope. Then when you get to your JSP you can use: This is better. You may need to play around to retrieve the strings you need in the form you need them. Personally I would create objects and add these to the collection. The objects are extracted and processed one at a time through the iterate loop. The you can use the name/property combo to retrieve any value from these objects.

another ActionForm-to-POJO binding tool: xsnapshot 1.1 beta released
XSnapshot 1.1 beta was just released to SourceForge.
http://xsnapshot.sourceforge.net/
This is an XDoclet module that helps you generate ActionForms from POJOs
with functionality for data binding/conversion between the two. You can
use it for a lot of other things besides ActionForms too, like
generating DTOs for remoting (Hessian, SOAP, AJAX/DWR, etc.) and I
suppose you could use it with JSF too but it hasn't been tried.
The advantage XSnapshot has over simpler solutions like
BeanUtils.copyProperties or the existing @struts.form tags is its more
robust conversion model. This can handle cases like POJOs with a
many-to-one relationship controlled by an in the HTML
form. The HTTP POST only sends back an ID, represented by a Long in the
ActionForm, and somehow that has to be reconstituted into an actual POJO
to update the persistent relationship (with Hibernate, anyhow).
An example of how you would mark up an object to generate a form:
/**
* @hibernate.class table="employee"
* @xsnapshot.snapshot-class name="form"
class="net.sf.xsnapshot.example.presentation.web.struts.forms.EmployeeForm"
* extends="org.apache.struts.validator.ValidatorActionForm"
*/
public class Employee {
/**
* @hibernate.many-to-one column="location_id"
* @xsnapshot.property match="form" name="locationId"
type="java.lang.Long" nested-property="id" copy-to-model="true"
*/
public Location getLocation()
}
This will result in an EmployeeForm with methods "Long getLocationId()"
and "setLocationId(Long)". (Simple string/int properties are much
simpler.)
Then in your Actions, you call XSnapshotUtils:
employeeForm =
(EmployeeForm)m_xsnapshotUtils.createSnapshot(employee, "form");
or
m_xsnapshotUtils.copyIntoModel(employeeForm, employee);
this presumes that a xsnapshotUtils instance is configured, normally via
Spring. There is an example app in the source distribution that shows
you how to do this.
The documentation is somewhat lacking, as there are only two regular
contributors to the project and we both have very limited time to devote
to it (darned customers!) But the example app in the source
distribution would show you how to set it up.

Re: Form Bean Question
Yes, you absolutely can use Struts with ActionForms. You will have to take responsibility for getting values out of request, and for validatation, etc., but the answer is yes. However, before you do that, have a look at this page: http://struts.apache.org/faqs/indexedprops.html If you want to still use ActionForms, this will probably help you do so. -- Frank W.

iPlanet 6 and Struts 1.2
I am beginning to believe that iPlanet is the root of my problems. I was successful in getting iPlanet to use the 1.4 version of the JVM, but it still does not resolves the MessageResources properly. In the debug log, I do see what looks like it is reading the files, but I do not see a "found this tag with this value" message, so I am not sure. I18N complained about not being able to find tiles-defs_en.xml and tiles-defs_en_US.xml. So I created these files too. Even without these files being in the struts config, it didn't complain about them. When a tag (such as tries to use a key, I get a null pointer error. iPlanet WS 6.0 is a 2.2 servlet container. Would this effect struts? THanks for you help. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

How to read an image from a db and display in an html page
Goal: Display an image in a .jsp page that is stored in a database blob
Synopsis: The blob is read into a byte array that is stored in the
ActionForm. The .jsp page uses a http://struts.apache.org/userGuide/struts-html.html#img
The code:
-- This reads the image in from the db
try
{
pictureStream = rs.getBinaryStream("picture");
byte[] bytes = new byte[1024*1024]; // some maximum size
int byteSize = pictureStream.read(bytes); // read in the bytes
byte[] bytesX = new byte[byteSize]; // create a new array of
the proper size
for(int i=0;i
-- This is the action code that writes the array to the response
public class JpegServerAction
extends Action
{
public ActionForward execute(ActionMapping actionMapping,
ActionForm actionForm,
HttpServletRequest request,
HttpServletResponse response)
{
WL_Logger logger = new WL_Logger();
SelectionForm selectionForm = (SelectionForm)actionForm;
try
{
response.setContentType("image/jpeg");
ServletOutputStream out = response.getOutputStream();
if(selectionForm.getPictureBytes() != null)
{
out.write(selectionForm.getPictureBytes());
}
}
catch(IOException ex)
{
System.err.println("JpegServerAction.execute: " +
ex.getMessage());
logger.error("JpegServerAction.execute: " + ex.getMessage());
}
return null; // tells the Action servlet to not do anything more
}
}

RE: writing images from a database
The only question I would ask is why your storing it in the ActionForm?
If it's request-scoped, that means you are reading the image from the
database with each request (or from server cache I suppose), which is
something I would suggest avoiding if possible. If the form is
session-scoped (which I see below that it is), I would be weary of storing
something as large as an image in it, most especially if you are working
in a clustered environment. Even in a single-server environment though,
it is always best to keep session size as small as possible, and a few K
for an image is something I would personally think long and hard about.
Do you have a reason for storing it in the ActionForm? Maybe you have a
requirement that causes that to make more sense?

Well now, *this* is a good way to go off-topic in a hurry Dave! :)
I personally feel just the opposite... the more comments the better, and I
don't generally care how "pointless" they are... well, ok, if I see:
a++; // Add 1 to A
... I tend to groan rather loudly, but that's a bit extreme :) When your
talking about all the myriad classes available in Java, it's virtually
impossible to remember them all, what their methods do, etc.
For instance, take this line:
String s = s1.toUpperCase().trim().replace('A', '-');
Now, that's pretty straight-forward. But, if someone added a comment:
// Convert s1 to all upper-case, trim whitespace from both ends and

doesn't have to remember what replace() does (i.e., does it replace ALL
occurances of 'A' or just the first?) and two, it indicates that the

Way too much for me. The only case I would appreciate comment in the
situation above, is when replace() were something like replaceAll() or
matches(). The comment would explain what regex is supposed to
describe.

I'm sorry, I have a cold. (Marginally obscure Monty Python reference.

I didn't mean to start a debate here?
I personally feel just the opposite... the more comments the better, and I
don't generally care how "pointless" they are... well, ok, if I see:
a++; // Add 1 to A
byte[] bytes = new byte[1024*1024]; // some maximum size
int byteSize = pictureStream.read(bytes); // read in the bytes
*oh, so _that's_ what 'read' does*
byte[] bytesX = new byte[byteSize]; // create a new array of
*oh, so _that's_ what 'new' does*
the proper size
for(int i=0;i*oh, so _that's_ what '=' inside a loop does*
bytesX[i] = bytes[i];
}
pictureBytes = bytesX; // assign it to the form variable *wait,
I already know what '=' does, but this isn't in a loop*
}
But all those *are* "add 1 to A" comments.
Besides the fact that the copy chunk should be refactored, you could
comment the entire block of code by saying "copy input stream to form
variable."
And I generally would use either an accessor or some sort of "this is an
instance variable" marker (like _pictureBytes or whatever) to remove one
more needless comment.
I like comments (love 'em!) but commenting every line in a 5-line chunk
of code is... silly. This example is obfuscating rather than clarifying.
String s = s1.toUpperCase().trim().replace('A', '-');
Now, that's pretty straight-forward. But, if someone added a comment:
// Convert s1 to all upper-case, trim whitespace from both ends and
replace all A's with -'s and store result in s
There's some sort of limit function here. As comment character count
approaches code character count something horrible happens. My head
explodes, and maintaining the comments becomes more cumbersome than
maintaining the code.
This is coming from someone that comments rather heavily, but sensibly.

The example I sent last night shows how to do that now, but it's not very artfully done. I'd like to be thinking about how to do what you're talking about. Right now there are 2 big pushes for Tiles that might hold this up: 1. Decouple Tiles from Struts 2. Decouple Tiles from Servlet API.

RE: writing images from a database
We had a similar requirement. We solved it in the same way. We
had the special image requests served by a servlet directly.
The servlet read the information from the database (also Oracle)
and streamed out the bytes to the user.
The DBA did tweak the database to perform moderately well
(Oracle 9, 10G is supposed to be better with BLOBs).
Also, we were storing user sourced images that came in any size
(usually 80kb). We used the JAI libraries to scale down the
images to a fixed size (about 7kb).

Re: prepopulating jsp page
You need your ActionClientAction action to create a new CreateClientForm
instance for the next page to work with. It can be quite seperate from
the ActionClientForm instance that's already passed in.
In other words, don't try to cast the form that's passed into the
ActionClient action to CreateClientForm; as you've observed, that
doesn't work since they are different types. Instead, just create the
new form instance and store it into the request (or session) ready for
the next page to read:
CreateClientForm newForm = new CreateClientForm();
// populate newForm
request.setAttribute("createClientForm", newForm);

Yes, the flow is like this:

This class goes to the db gets the information then forwards to editClient.jsp
which has the action mapped:
type="com.medina.web.action.UpdateClientAction"

So when I tried to re cast it it threw a class cast because I was trying to cast actionClientForm to createClientForm.
The bean named createCleintForm is of class createClientForm which is mapped in
the form beans of config.xml.
Does the same still apply?

Ok, so you have a different formbean coming in to this action:
The bean named createClientForm is NOT of class CreateClientForm?
If you have a bean class other than the one mapped to the executing action
that you want to populate and later display in the success-form, then you
have to:
1 create the bean
2 populate it
3 put it in page/request/session scope
4 return from action
5 in jsp, get the bean from the scope you put it in

I cannot do the following
CreateClientForm updateForm = (CreateClientForm)actionForm;
Because the action is called from a search page and has a
different form coming in. Thus when I try to reassign it I
get a class cast exception.
I also tried the first way you mentioned, but that did not
populate the form either.

If your display:table is using the RowSetDynaClass as its data source,

Multipart Form Validation
Is there a reason I am losing my request parameters when returning validation errors to a multipart form page? I have a simple struts form. It has a few text fields and a file field. The enctype is multipart/form-data on my form. I validate in the actionform's validate method. If the text fields are empty, I return errors that they are required. Along with the visible fields, I pass a few hidden fields that are needed as request params when the form is processed and returned to the jsp. The jsp needs these request params. Everything works great when there are no validation errors as the request params get returned by using the ActionRedirect class in the action. But if there are errors returned, I lose the request params. (I am able to access them in the actionform validate method or in the action). If I perform a test of 2 identical forms with a few required text fields, one multipart one url-encoded, the url-encoded form maintains the request params when validation errors are returned and the multipart form does not. What am I doing wrong? How can I make sure the request params are passed back upon validation error in multipart form? Thanks!
downloading a file using struts action class
I want a struts action class to download xml file .I
do not want to use Struts DownloadAction because I
have a super class called AbstractActionBase which
extends to struts action class and all my action
classes extends to this AbstractActionBase.
For downloading a file I am using normal struts action
class rather than DownloadAction class (I do not want
to use struts DownloadAction).
This normal struts action class returns null instead
of ActionForward and sets the response content type
and writes to reponse output stream . My question is
is this proper way towrite a download Action in
struts without using struts DownloadAction class .
Here is the code fo my download action class
public ActionForward performAction(
ActionMapping mapping, ActionForm form,
HttpServletRequest request,
HttpServletResponse response) throws Exception
{
ResultsForm resultsForm = (ResultsForm)
request.getSession().getAttribute("resultsForm");
FMCDataDocument fmcDataDocument =
resultsForm.getIdFlagFmcDataDocument();
byte[] bytearray =
fmcDataDocument.xmlText().getBytes();
response.setContentType("application/rss+xml");
response.setContentLength(bytearray.length);
response.setHeader("Content-Disposition",
"attachment;filename=sample.xml");
response.getOutputStream().write(bytearray);
return null;

It should not be necessary to manipulate the request object manually. The
"preprocess" chain is executed by ShaleApplicationFilter (as the name
implies) *before* FacesServlet is invoked ... and, from within a command,
you can do either a redirect or a forward in the usual way. The important
detail would be to make sure that your preprocessing command then returns
"true" instead of "false" ... this tells ShaleApplicationFilter that you
have already created the response, so it skips the usual chain.doFilter()
call that passes the request along to the original servlet.
To do a redirect:
HttpServletResponse hresponse = (HttpServletResponse) swcontext.getResponse
();
hresponse.sendRedirect("foo.jsp");
return true;
To do a forward:
ServletContext scontext = (ServletContext) swcontext.getContext();
RequestDispatcher rd = scontext.getRequestDispatcher("/foo.jsp");
rd.forward((ServletRequest) context.getRequest(),
(ServletResponse) context.getResponse());
return true;
It seems like a simple Forward bean could be included in the Shale

That would make sense. Then you can use settings in your
faces-bean.xml file to set the appropriate security values, without having
to hard code them.

Re: [OT] Re: writing images from a database
I agree with Frank, we all started with Java/Struts somewhere and back then the
more
comments in the code made it so much easier for us to understand. The people
who
come after us will also be learning, let's make it easier for them.
The only time you should reduce comments is when your compiler times-out while
parsing your source code.

Struts hangs on
I'm having a problem where Struts has begun 'hanging on' to Web browser requests. I'll call up an Action and the page comes back pretty instantly, as you'd expect, but the little 'still-downloading' image keeps whirling for about 30 seconds. I've tried to track this down thorough my debugger but the request flies through to the end of the Action.execute() method, where I return a forward. Sometime after that it hangs for about 30 seconds, then the request completes. This happens for all Actions in the project. I'm using Tiles, if that makes a difference. Does this symptom sound familiar to anyone? Any suggestions would be appreciated. Dave Bender

Slightly agree, but again, in general, this usually over-obfuscates (for me, anyway :) Part of why I say that is because I almost never touch Java code outside of an IDE these days: I hover, it tells me what I need to know; I double-click an can go to the declaration, etc. I'd probably use a comment here rather than messing with the mainline code, though. In my own code it's pretty rare I'll have an in-line comment. I'll comment large functional blocks of code, and I JavaDoc most everything pretty thoroughly (except packages, which I need to get in the habit of). That said I rarely have methods that are very long, I use descriptive variable and method names, and that seems to eliminate most confusion.

While not strictly Struts related (I do use Struts in this app) I am hoping that someone else on this list has gone down the same path as I am attempting.

Re: [Hibernate] Lazy again
Hi Martin I'm not using spring, not sure if I should be. I recently tried writing an app using Hibernate and had some great experiences - it's pretty cool in the amount of code and development time it saves me. Having said that I'm struggling with the same problem. I open the Hibernate session in my Action class, update / access the data and then close the session. I get the "session is closed" when the page begins to render properties from my bean (where those properties originated from related tables). Reading through the Hibernate manual it indicated that by specifying fetch="join" the related table would be retrieved in the same select statement. I tried this but got the same "session is closed" result. It also said that you could specify lazy="false" and it would retrieve everything at once, however it immediately recommends you don't do this for lots of good reasons (I did try some but they didn't seem to work, maybe I put them in the wrong place). How does the filter modify this process for you? It doesn't sound like it has solved the problem.

Re: writing images from a database
Actually, if you are going to build a servlet with this capacity, it should handle all such resources, not just images. You can, e.g., make big savings with using these for CSS, etc. On 9/29/05, Michael Jouravlev <[EMAIL PROTECTED]> wrote: > On 9/29/05, Braun, James F <[EMAIL PROTECTED]> wrote: > > With the help of this list and some digging I think I came up with a > > relatively elegant solution (subject to expert critique which is > > welcome).

Re: [OT] Re: writing images from a database
I think the idea is to make code clear. If you cannot possibly make the code clear without comments, then put the comments into the code. Gratuitous comments are counter-productive.

Re: [OT] Re: writing images from a database
This is directly contrary to best practices. What really would have
helped in Struts would have been if someone had discussed some of the
naming conventions prior to committing them. They are particularly
bad in Struts. However, best practices is to make the code clear
first. If that is not possible, only then comment. OP

Re: [OT] Re: writing images from a database
Lord, if there were gigabytes of comments that would be bad. Horrible. A disaster. Something to cry about. However, there are not. So that is good. Very good. Something to smile about. If there is anything like a whole bunch of comments, that is the sign of an amateur and the same is true about no comments and unreadable code.

Re: [Hibernate] Lazy again
Reading through the Hibernate manual it indicated that by specifying fetch="join" the related table would be retrieved in the same select statement. I tried this but got the same "session is closed" result. It also said that you could specify lazy="false" and it would retrieve everything at once, however it immediately recommends you don't do this for lots of good reasons (I did try some but they didn't seem to work, maybe I put them in the wrong place). How does the filter modify this process for you? It doesn't sound like it has solved the problem. The filter opens a single session as early as possible in the servlet request, and closes it as late as possible; this lets you write most of your code trusting that there is a current session which relates to recently retrieved objects. Google for "Open Session In View" and you'll find lots and lots of writeups about this pattern. Regarding Martin's question, the filter should be mapped to whatever your Struts actions are mapped (as in the conventional *.do) if you want your Struts actions and the views to which they forward to take advantage of the filter. I've been using Hibernate for a little while and have adopted the Open Session in View pattern for the application I'm currently developing. There are definitely a few things you need to get used to, so it is worth doing a decent amount of reading. In fact, I would say that while you can do a good amount with Hibernate without much study, there is much careful thought behind the framework and you will use it much better if you learn the reasoning behind some of the implementation decisions. (Hibernate in Action, written by Hibernate founder Gavin King, is a very fine book; one of the most usefully theoretical technical books I've read in a long time.) If you have a relatively simple object model, you can do just fine without "Open Session In View" -- just make sure that all your associations are marked as non-lazy or explicitly indicate the Fetch Mode in queries when you know that the associations will be followed, or use Hibernate.initialize(...) to make sure that the initialization happens (remember that it is not recursive, so you need to apply it to each lazy collection, and you must do it before the opening session has been closed, or you must use session.lock(...) to reattach your detached persistent objects before trying to traverse lazy associations. (If this all sounds like gibberish, read Hibernate in Action!)

Hibernate data at startup
I have Menu information for my app in the database which I would like to be able to load somehow when my app server starts up (or app is deployed). This would be much more efficient than the current method of having each user load it when they enter the application. Can anyone suggest how to best go about doing this? The architecture is Struts, Hibernate and Spring. Thanks Marty - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Hibernate data at startup
You have a few options. To initialize Spring, you can either use the Struts plugin or the web app context listener. Once that's done you can either use a startup servlet or a Struts plugin to load the data and put it into the servlet context. That way it only needs to be loaded once and is shared throughout the application. It's pretty simple, but not very obvious.

Problems with nested beans and displaying information in a dropdown box
I have a form that contains a bean with a nested collection that I'd like to
prepopulate but I'm having trouble displaying the correct information.. The
output html wiould ideally look like this:
Jon Doe
Jeff Newworth
Amy Madigan
The ActionForm contains the bean with nested beans and the error mesage I
get from Tomcat is "Cannot find bean under name customer".
My form and bean classes are defined as:
public CustomerFormBean extends ActionForm
{
CustomerBase getCustomerBase() { return customerBase; }
private CustomerBase customerBase;
}
public class CustomerBase
{
public Object[] getCustomers() { return customers.toArray(); }
private ArrayList customers;
}
public class Customer
{
public String getName() { return name; }
public String getId() { return id; }
}
My jsp code looks like this:
Could some one point me toward the right direction in helping me understand
what's wrong here?
Thanks,
