error on struts 1.1
hi, on this pg of struts 1.1 documentation, http://localhost/struts-documentation/userGuide/installation.html (don't know on-line equiv. of this page, as link to 1.1 on this page http://struts.apache.org/downloads.html#PriorReleases gets you a 404..) it says where to put jar's, tld's, etc.. but not dtd's... what are dtd's and where do they go?

Re: error on struts 1.1
my gosh, you are right hmm.. interesting.. ok, so I need to know certain basic things.. I assume general rule, regardless of version, is jars always go in WEB-INF/lib, tld's, go in WEB-INF/.. but couldn't find tld's, so searched for them.. found them in different directories, some in src/taglib/src/main/resources/META-INF/tld, some in src/el/src/main/resources/META-INF/tld.. this is a bit confusing.. why don't they just put all tld's together? it doesn't say anyting in this pg, http://struts.apache.org/1.3.8/userGuide/installation.html as far where to put tld's.. I assume tld's always go in WEB-INF/.. is this correct? (I just downloaded struts-1.3.8-lib.zip, doesn't even come with tld's.. how is this possible? tld's are always needed, aren't they? simplest would be a folder called 'tld' w/all tld's in there.. gosh, this is a bit messy, not sure what tld's will need.. from all the different tld's I found in diff folders in src version... same thing w/dtd's -- are they needed? if so where do they go? and which ones do I need? when search for dtd's in src download find a million of them, in different folders... oh brother... thank you...

what version is best..
hi, I started a new job recently where they use struts/tiles for everything, I had never used this technique before and would like to learn it well.. when I go to http://struts.apache.org/downloads.html I see versions 1.0.1, 1.2.9, & 1.3.5.. but all books I have checked out online don't cover 1.3.5 yet.. (Oreilly's Jakarta Struts 2nd Edtion, for example, covers only 1.1.. as does wrox's struts book..) I'm running Tomcat 5.5, JVM 1.4.09.. does it matter what version of struts framework I use? I just want to find a version that when I buy a book that version will be covered in the book... does it matter if I don't use latest struts version? thank you.. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

struts-html question.... puzzling problem...
hi,
I'm following chapter 3 of Wrox Struts book ("Professional Jakarta
Struts") to the letter.. using struts 1.3.5, Tomcat 5.5/1.4... get
TLD-related error on index.jsp (entire zipped-up webapp (small,
virus-free...:) here... www.mayacove.com/java/strutsWrox.zip)
did index.jsp, and the classes, all following instructions in the book,
the classes (LookupForm and LookupAction) compile fine.. put all
packages (.jar's) from Jakarta Struts download where they belong
(WEB-INF/lib..)
in index.jsp is this tag:
I looked in struts-html.tld itself, one thing I note is that under
"form" tag there are no attributes defined for either "name" or "type",
only for "action" (which can also be seen here,
http://struts.apache.org/1.3.5/struts-taglib/tlddoc/html/tld-summary.html)
so am a bit puzzled here
one thing I also noted is that JSP servlet for index.jsp is non-existent
(when look in tomcat/work/ don't see either index_jsp.java or
index_jsp.class..) i.e., JSP for some reason is not even being read by
container..)
I have in struts-config.xml:
name="lookupForm">
in LookupAction.java:
LookupForm lookupForm = (LookupForm)form;
(this is confusing: so lookupForm is name of form but also an
instantiation of the other class in the package...(??)
would much appreciate some help.. thank you..
(posted a question on Wrox's website relevant forum about two days
ago but have gotten no response..)
thank you very much.

Welcome to the world of Wrox.
(Sorry, Wrox.)
As mentioned, you need to look at *current* Struts documentation; that
book is like 3(?) years old and was written for Struts 1.1 (I imagine).
Struts has changed since then.
Dave
thank you very much.. yes, the book uses 1.1.. I can't find any book
that uses later versions, no 1.1 download on Jakarta site.. this is all
very puzzling and confusing.. and Wrox, unlike oreilly, there's no
e-mail contact for the authors (the few times I have written to oreilly
authors I have always gotten a response... oh well...)
thank you... need to learn struts, what to do? really can't find any
book that covers 1.3.5..

thank you all very much for your help.. finally got it to work w/struts 1.1 (I had tried earlier version before, but 1.2.9, since hadn't been able to find 1.1) now need to deal w/WAR-file thing, unfortunately don't know how to unpack/deploy WAR files.. I tried about a year ago to learn to use WAR files, couldn't get it to work.. there is indeed a struts-documentation.war in the 1.1 download.. found WAR-file instructions for example here, http://www.jguru.com/faq/view.jsp?EID=123229, but it's for tomcat 3.2.. I hope this will work on Tomcat 5.5 (since struts 1.1 is rather old..) can I assume url for docs then will be struts-documentation/index.jsp? how exactly does this WAR-thing work??? :) again, thank you very much..

Hi-New to this group
Hi all, I am designing a web app/ Its supposed to have 500 concurrent users. 1. Module- Login The users login using their uid/password and see the stuff in their database I am planning to use Struts,jsp,action classes in the front end Now, back end I am thinking about session ejbs which reads database tables. The method for getting values from database tables will be implemented in a DAO. Now, what should I use in the middle layer ? ie, intercation between action classes and session ejb: For a struts based appp, whats best here ? Again 500 concurrent users. Thanks __ Do You Yahoo!?

RE: Struts with Eclipse 3.1
Yes, I was trying that. I created an empty "Web project" in eclipse and imported struts-sample.war. But this created two WEB-INF directories and 2 web.xml files. Looks like when a web project is first created, it already creates the web.xml and web-inf directory,a nd when the war file gets imported, it creates it again. So, I created a simple Java project and imported the war file. But functionally, will it work. What other suggestions ?

Struts-Jsp display
All, I have a requirement in which I display reports in a jsp using Struts. The reports pull huge data like 3-5 records will be in the jsp page. Right now, I get the records in an array from my DAO and then set them to my form bean. In results jsp, I iterate through it and use tag to write all values in jsp. This approach is pretty slow. After it displays all records the page simply hangs. From IE page I cannot move forward/backward etc Can anyone suggest an improvement ? In DAO i just do JDBC select and get the records. JDBC retrieves query fast. Thanks. - Got a little couch potato? Check out fun summer activities for kids.
Struts 1.2 using formbeans
Hi all,
I need some help here.
I am using Struts 1.2
1. I have inputForm1.jsp where I input 2 values and then fetch the 3rd value
using a Submit action. This has been mapped to Submit.do and inputFormBean is
referrenced in the struts-config file.
Inside action class Submit.do, the 2 input values are read from InputForm and
third value is obtained from DB.
Then I set this 3rd value to the inputform using setter method and do a
mapping.forward("inputForm1.jsp")
However, when inputForm1.jsp gets displayed, all fields are null. No values
for 1,2 and for the newly fetched parameter 3.
What am I doing wrong ?
Again, I have
inputForm1.jsp -> SubmitAction->InputFormBean
In submitAction, I call setter method of formbean and sets the 3rd parameter
and do
mapping.findforward
Thanks,
-

i TRIED SETTING THE REDIRECT=TRUE ALSO, but still it doesnt display the values when coming back to the original window. Can this be an issue ?

Re: Dynamic combo boxes
Thanks for the response Abhiram,
I tried using styleid,
But how do I give [use] dynamic styleids ? There should be some way to
retrieve the particular combobox for a particular row right ?
I tried using styleid=bean:write id=index> where index is retrieved from
logic:iterator tag
Have you tried it, This way the styleid was not getting dynamically populated
abhiram <[EMAIL PROTECTED]> wrote:
ur requirement is to change contents of combobox 2, when a different option

i think you can give id to each combobox,write an onchange event or something
similar to activate javascript
in javascript, get the selected option of combobox 1 by using
document.getElementById("id of combo 1").value
write some condition on this value, and change the value of combobox 2
accordingly.
because u hardcode the ids, u can just access the comboboxes using their
ids..this should work whether ur comboboxes are static or dynamic.

best possible design
All, I need to enable role based access to my Struts-J2EE application. ie, if a normal user logs in, user should see one page whereas if a superuser logs in he should see another page.

General question
I have a struts based J2ee app which displays data from DB in the results.jsp page. For DB data access, I use a DAO which returns a serialized object. This serialized object, I set it to request object using setAttribute and retrieve it using tag i n jsp page. My question is: if users try to open another window and do simultaneous tasks, how can I avoid same user from working in two or more different windows in a Struts based j2ee application ?

Re: General question
Dave, Thanks for the reply. Yes I had the variable initially set in session. Then when I did Cntrl+N[open new window] from the existing browser window, I see the same result in the second window. Even when I set it in request object and do[open new window] the same result is being displayed. what way can the appearence of DB values be prevented in multiple windows ?

I don't know as you can (easily), but your scenario doesn't describe a situation in which that would be a problem. *Session* variables can be a problem (browser-dependent) but request-based variables shouldn't be an issue.

JNLP with struts ?
Have anyone used java web start[JNLP files] with struts ? I have a project which uses struts. Now i have a Login.jsp, which calls Loginaction.java. If user is a valid user, then I have to initiate a call to a "jnlp file" .

Real time data display in a struts based application.
All, Have a design issue here. We have a web based application and have 2000 concurrent users. The requirement is: when new data comes on Oracle database for users this data has to be sent to the online users on a real time basis. Someway, the real time data needs to be pushed to the users without the client doing a reload/refresh etc. What technologies can be used here ? Can anyone provide me some suggestions ? The users login to the application using a web page, this is a web based J2ee application using struts, Oracle database. Thanks, Maya - Any questions? Get answers on any topic at Yahoo! Answers. Try it now.
Re: Real time data display in a struts based application.
Thank you both for your responses. So AJAX is the technique I should refer. Anyone know of any examples / somethings. Also, my colleague asked me this question when I talked to him about a "timed AJAX event". Why cant we simply refresh the jsp page ? Why should we use AJAX ? so, whats the real advantage of using an AJAX timed event to a normal JSP/HTML refresh ?

Re: Real time data display in a struts based application.
Thanks Musachy for your response.
We use Struts 1.x right now.. Guess we have to update..
Please send me if yu have any examples/links..
Musachy Barroso <[EMAIL PROTECTED]> wrote:
You can refresh the page, but that would probably be annoying to the user,
not to mention that data entered on fields will most likely be lost. Using a
div you can update just the part of the page that is important. Using the
div tag in struts:
theme="ajax"
href="%{ajaxTest}"
updateFreq="3000"/>
that will make your div reload the content from "AjaxTest.action" every 3000
milliseconds. There are many frameworks available, so you can pick one that
fits your needs. For simple scenarios, the div tag will do.

Re: Real time data display in a struts based application.
Ok, got the difference. Now being a new bie to AJAX, what are the best techiques that should be used to design a well designed web app ? Again, my page has to show the new data thats being added to database. Frank told about creating a "timed AJAX event". Where can I get more details regarding that ? Again will it be possible /scalable for 2000 concurrent users ?

Re: Real time data display in a struts based application.
Musachy,
Yes, we use struts 1.x, and I really dont think we can download any of these
external libraries.
So said so, I have to write javascript etc to achive these "AJAX timed
events"..
Any one has done it to achieve it ?
I believe javascript,XML etc are needed.. any examples.

Session Management
All, I have couple of questions while designing a web app using struts. My application uses Httpsession variables. 1. How do we handle a user from opening duplicate sessions ? Like if a user is already logged in, if he/she tries to login again, system should mention that user is already logegd in. How do we do that ? 2. Also, back buttons. Back buttons shoudlnt display anything [like no data] should appear when user clicks back button How to handle these two situations ? Need suggestions. Thanks, Maya - Don't be flakey. Get Yahoo!

Re: Global forwards and actions
well, Here is exactly what I have: 1. jsp files are in /jsp folder. struts-config file entries and action classes. struts-config entry is like this: Monkeyden <[EMAIL PROTECTED]> wrote: If that's the error you're getting, then that can't be your code.

Handling attribute values
Hi all, 1. I have an action class, DisplayAction which displays the records from database. Here I am setting a vector into the request scope and on success forwarding it to displayresults.jsp. 2. Display results.jsp displays all records with an option of delete to the users. 3. Now, once user deletes the records, by going to editaction, on success it should again display the displayresults.jsp. How will I get the attribute I set in step one here again. what path should I follow ? DisplayAction -> displayResults -> EditAction EditAction should again display displayResults and get the attribute set in DisplayAction. Please help __ Do You Yahoo!? Tired of spam? Yahoo!

From my database, I have an object [a data object], ListData with following information returning string result; Vector itemList; //list of object 1 ArrayList itemList1; //list of object 2 In my JSP, I have th reference to ListData object, I know I can use >bean:write and get result. Now, for getting fields within the arraylists, is there any tag which I can use ? I have to -> iterate thru the list, which gets me another dataobject with getter method. -> then use dataobject's property its like a vector inside an object. Any ideas ? - Yahoo!

Re: Tags in struts
Thanks Adam. Yes, I have a bean lets say, Testbean with two Collections. I have to display the value of these Collections[has objects] in a select box in my JSP. Can you send me the sample code please ?

Probably the easiest way I've found is to use the LabelValueBean object and construct a java.util.List of these objects from your model data. Then, following the example at http://wiki.apache.org/struts/StrutsWidgets, you can use the html:optionsCollection element and the "value" and "label" attributes to retrieve the value and display name (two separate things) of the item selected in the listbox. Since I just implemented this late last week, I can post an example if you'd like...it's pretty straight forward once you grasp how to use it (although, it was this last part that took me a while too...) Alternatively, check out the Radio Group section of the above listed URL, it provides an example using logic:iterate and bean:write but I don't think it allows for different bean getters...someone please correct me if I'm wrong. > > I have to > -> iterate thru the list, which gets me another dataobject with getter > method. > -> then use dataobject's property > > its like a vector inside an object.

If so, you'll want to just set an attribute on the request with the result of that getter method as I don't think there's a way to handle it otherwise. I did this last week also, so if you want, I can post that code as well. -Adam - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] - Yahoo!

Re: Tags in struts
Thanks Adam
Implemented it and it worked.
One quick question, when we use these tags, one of the options get selected
by default. How can we modify the tag so that NONE of the options get selected
by default ?
Thanks.

Let's say your TestBean class has getFoo() and getBar() methods both
which return Collection objects. If these objects are instances of
LabelValueBean objects it's really easy, if they are not, I'd recommend
converting them to these bean objects either in your bean class or in
the action (though the latter could add additional overhead if not done
correctly). Assume also that your TestBean class has getter and setter
methods for ONE Foo and ONE Bar (say getOneFoo(), setOneFoo(String foo),
getOneBar(), setOneBar(String bar).
In your Action's execute method (or a method called by execute(...))
type (assume testBean is an instance of the TestBean class and the
getFoo() and getBar() methods return Collections of LabelValueBean objects):
public ActionForward execute(ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response)
throws Exception {
...
Collection fooCollection = testBean.getFoo();
Collection barCollection = testBean.getBar();
request.setAttribute("fooCollection", fooCollection); //
"fooCollection" can be any text you want - i recommend using a final
static reference instead of a hard-coded string.
request.setAttribute("barCollection", barCollection); // same
comment applies
...
}
in your JSP, you would say:
your collection on the request -->
property="value"
labelProperty="label"/>
and,
property="value"
labelProperty="label"/>
to render list boxes of your model data.
html:options knows that you have a Collection of objects (in this case
LabelValueBean objects) that have the methods getValue() and
getLabel(). Note that since these attributes are configurable, you can
make the Collection a collection of any type of bean you want so long as
all the beans in the collection have a getXXX() methods where XXX are
the values of the attributes "property" and "labelProperty".
When your form is submitted, the setOneFoo(String) and setOneBar(String)
methods will be called and set with the value of the "property"
attribute. the "labelProperty" attribute dictates what is actually
displayed to the user in the browser.
Let me know if you have any more questions.

Re: Tags in struts
Adam,
Thanks for the suggestion. I checked with our users, they didnt like the idea
of inserting a text in the listbox. They see it as confusing.
So, ideally my users lik to have listboxes with No values selected...
Any idea how it can be achieved ?
Thanks.

Excellent! For a list box, I believe that you must have at least one
option selected at any given time. If you don't want to provide a
default and force the user to actually select one (and then you can
validate the user's input to ensure he/she has actually selected a real
value) then you can do what we did.
For our Time Zone list box, we created the list of time zones and also
inserted a text label of "Time Zone" with the value of "" into the
LabelValueBean List and then in the Action that is executed before the
JSP page is rendered, we set the property on the bean. So for our time
zone it would be beanInstance.setTimeZone(""). This defaults our time
zone list box to display "Time Zone" and if the user tries to submit the
form without selecting a time zone, our validator informs them that they
must select a time zone.
Glad it worked.

RE: Tags in struts
Yes Adam. Thanks again in the nested:select tag you can add value="", that changes the display in such a way that none of the needed options ar selected. Thanks again. Now, my display is perfect, have to think about how to update options in this list box now using javascript. -Maya Adam Gordon <[EMAIL PROTECTED]> wrote: Maya- A. I understand now. You want a list box, not a drop-down list. Drop-down lists require that one, and only one, item be selected. List boxes allow for zero, one, or more options to be selected. Check out the "Dropdown box" section of the Struts Wiki: http://wiki.apache.org/struts/StrutsWidgets It explains how to have the tag render as a list-box rather than a drop-down list. I've not yet used a list box but I imagine if you set the bean property (that matches the property of the list box) to the empty string (or perhaps even null), no item will be selected when rendered. Hope this helps. -Adam -----Original Message- From: Maya menon [mailto:[EMAIL PROTECTED] Sent: Wednesday, 12 July 2006 07:21 To: Struts Users Mailing List Subject: Re: Tags in struts Adam, Thanks for the suggestion.

Re: Tags in struts
ok... good thought, looking at Javascripr right now to edit the options in list box.. -Maya Adam Gordon <[EMAIL PROTECTED]> wrote: Maya- Just had a thought...you can set the "style" attribute on the element to say 'style="display: none;"' to hide a row in the list.
