html form widgets not appearing
My pages are showing up fine and the form Actions are working, w/ one exception, all of mypages are not displaying any of the form widgets like radio buttons or text entry boxes and even bean message keys, yet no errors are occurring. Is there anything wrong w/ the below page that would prevent forms from not showing? A problem I had before of not findingmessage keys was thatin the taglib lines where the prefix was only - prefix="bean" - and I actually needed - prefix="struts-bean", though I've seen no examples of it anywhere's, just from somebody's post, so I tried it and it worked.

I don't get it, if I match prefix=struts-bean w/ a tag of bean:message key ... it can't find the keys in the properties file, which I'd say is to be expected.

Title: RE: html form widgets not appearing
The entire index.jsp file is included in this
message so you can see the html source at the end. I havn't actually re-compiled
the struts.jar file to see what was happening (because it wasn't easy to get
working w/ orion server)but just by looking at MessageTag.java,I
could see where in doStart() the message var came back as null and threw the
exception when trying to read the key. I sawthe file it was trying to read
was correct bydoing
aprintln(getClass().getResource("my.properties")... in my jsp file.
I'll look at this loadLocale to see how and where
to use it. Thnxs.

What does the html source look like? You also might want
to check the method loadLocale() and make sure the message strings are being
loaded from the file.

Heh, I've been on this prob for almost two weeks and I'm
loosing motivation in this project because of this
bug. My servlet config I believe is correct. I made it
as simple as possible by putting the cais.properties file in the
~/WEB-INF/classes dir (no package path) and saying:
!-- Action Servlet Configuration -- servlet
servlet-nameaction/servlet-name
servlet-classorg.apache.struts.action.ActionServlet/servlet-class
init-param
param-nameapplication/param-name
param-valuecais/param-value /init-param
Other keys are not being found as well. I know the correct
file is being found as I println the
...getClass().getResources("cais.properties") and it shows it's got the correct path and according to the struts code,
it's finding the file, but not the key.
I'm pretty sure I'm referencing the key correclty:
%@ page language="java" % %@ taglib uri="/WEB-INF/struts-bean.tld" prefix="bean" %
%@ taglib uri="/WEB-INF/struts-html.tld" prefix="html"
%
html:html head
title
bean:message key="main.title" / /title

Well, at least now you know you're invoking the
bean:message tag. ;-) That's a problem I've
found with debugging custom tags: if you forget the taglib directive or screw it up, you get no complaints.
It seems to be saying it
can't find your message by that key. Can you find any messages? Do you have the
correct reference to the properties file in your
web.xml file, e.g.: !-- Action Servlet Configuration --
servlet
servlet-nameaction/servlet-name
servlet-classorg.apache.struts.action.ActionServlet/servlet-class
init-param
param-nameapplication/param-name
param-valuecom.propel.webapp.Resources/param-value
/init-param
In my case, that means the
file is at
webapproot/classes/com/propel/webapp/Resources.properties . I
don't think it
necessarily has to be there (isn't there some search path for finding
it?), but that has worked for me (using resin).
Make sure you can find any
message and then make sure your tag is
referencing the message key correctly, e.g., I would expect given what
you've said it would be: bean:message
key="main.title"/ Scott

Re: html form widgets not appearing
The problem happens on 1.4.5, 1.4.7 and the latest (which is gotten from an autoupdate utility) 1.4.8. The earliest I can use w/ my app is 1.4.5 because of other fixes. Unfortunately, I need an EJB container, so can't use Tomcat unless I get JBoss which is a J2EE config nightmare for me at this point. I do have one struts.jar (which is not in the classpath and I removed for testing) in which I use to have ant package my *.ear file before it get's deployed to the same account I use to develop this in. But I've removed it after deployment to see if this was the problem. Nothing different. I would think since I'm using the struts controller servlet, I can use the standard resource factory implementation which is what I'm doing, as opposed to a previous suggestion to develope my own. This *seemed* easier and I'd still like to find the problem. I'm just going to have to keep sprinkling struts.jar with println()'s till I see where/how/why it's not getting this file. - Original Message - From: Dan Miser [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Saturday, April 28, 2001 12:22 AM Subject: Re: html form widgets not appearing What can you do to help isolate the problem so others can see it?

of the server and inside a new account and there are no other resource files in
my classpath or on the machine.

According to the above error and this snippit of
code taken from the 4-20 tar.gz source, the properties file that my web-app is
looking for*is being found* and all seems to be setup/configured
correctly, otherwise theerror would be about messageTag.resources (not
finding the property file). So for some reason, the key can't be gotten from the

The only thing else I think that can be wrong is
the value of the args array just before the Exception is thrown and I was
wondering if anyone could tell me what those might be.
The linewith 'String message =

giving me the above error, but I'm not sure what's being stuffed into it or
where it comes from.

How can I still get the following error if I've commented all my bean:message tags out from the below file?

Well, I'm using Orion so this isn't the case. I get the error just after a
fresh install and configuration of a new account.
Any more ideas appreciated.

Hi,
I got exactly the same error in VAJ-Tomcat environment when I first time
load my own project after running the struts-examples successfully.
It turned out that Tomcat mixed up the property files that are loaded
into its environment and could not figure out who is who.
Fix:
Leave only the project you are working with in Tomcat's classpath
and projectpaths.
For me in VAJ, I have to also delete the JSP compiled servlet project
to clean it up.
Hope it helps,

Re: entity beans within an Action
So would I have to do a setAttribute to store every session? Is there someway to uniquely identify each session by it's attribute name, or how is that often handled, since I think I'm going to have to give it a unique name for each setAttribute.? Thnxs for the responses. - Original Message - From: [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Tuesday, April 03, 2001 8:54 AM Subject: RE: entity beans within an Action Hi Gary, To keep track of a stateful session bean (or any other object for that matter) across multiple requests, you will need to store its reference in the session using setAttribute(). You will also need to perform a check in the Action each time a request is processed to see if that object already exists- use getAttribute() and see if it returns null, and if so then create it. I suppose there are other ways to do this, but this is probably the most direct way to do it. Keep in mind that stateful session EJBs might be overkill for what you are trying to accomplish. You could just gather input and populate your same ActionForm using multiple input forms- then when the last form is submitted write the changes to the entity EJB. You will still need a session EJB to do this properly, with methods like saveUser() and getUser(), but there is no need to make it stateful. You should consider stateful if you need to write the changes after each input form is completed- if you can't wait until the last page is submitted. Regarding the field-to-field copies from an ActionForm to an Entity bean. This is the way I am doing things and it is working out nicely. Just make sure you name your fields the same and use the Struts PropertyUtils.copyProperties() method to do this work for you if possible. It would work even better if copyProperties could make simple type conversions :) Some may oppose this design- having the session EJB be aware of the ActionForm- since it somewhat couples the presentation to business, so if this bugs you then you could use an interface instead- let the session EJB be aware of the interface instead of a specific ActionForm (more details on this were posted by someone else a while back- last week I think). One thing you should not do is perform the copy operations from within the Action. Make sure you pass the entire data structure (i.e. the ActionForm) to a session EJB and let the session EJB invoke all the setters/getters on the entity EJB- either directly or via the Struts copy util. One short note on stateful session EJBs too... Some avoid using them for performance reasons. If you are building a high demand site then you may want to avoid using them. They can't be shared and pooled the same way stateless beans can- just make sure you really understand the lifecycle before you use them. I can't speak from personal experience on this, perhaps someone else can, but this is just what I hear through the grapevine. I am sure a lot depends on what EJB container you use as well. -Bob -Original Message- From: G.L.

The container manages the creation, passivation, destruction, etc... of the EJBs. When you "create" an EJB from your Action for example, you are just asking the container for a reference. Of course there is some overhead with looking up the bean's home interface and creating the stubs- but this should be negligible (compared with instantiation of the actual entity bean). However, If you know that many requests within the same session will need access to the same entity bean(s), you could create a stateful session bean and keep track of its reference in the session. I have an Action that spans multiple pages. I have only one ActionForm class to go w/ this Action for the multiple pages, so the user makes multiple submits on the same ActionForm. This part I don't get. If I've done a lookup and gotten the reference of this stateful session bean, how is that returned reference kept for the next time the Action is called, afterall, the Action was destroyed. Must I do another lookup everytime the Action is called to get the reference to the session bean? I can understand how the session bean itself can hold a reference to the entity bean, since the stateful session bean itself persists. Also, I guess as the last step in my conversation it's ok to do regular field-to-field copies of the ActionForm data into the entity bean. After writing all this out trying to explain it to you guys, I think I've just answered my question and am looking for a "yes, you're on the right trac
entity beans within an Action
If the life-span of an Action is only when that Action is being exec'd (which is also where I implemented my session bean since it's life-span is also not neccesary to hang around), where should entity beans be initialized and populated by data held in the ActionForm bean? Seems if I init'd them within the Action, I'd be creating a new Bean everytime it ran through that Action, same w/ the session. Am I going about this wrong? Any help much appreciated.

init'ing a session bean in Action
Probably not the right group and I'm new to ejb's and am having a problem
getting a sesson bean going from within an Action class (a class from the apache
struts framework which probably doesn't make a difference what the class is). Is
this on the right track to doing this correctly, though I get the following
error.

ActionServlets calling Actions
From the API of the Action class: "The controller (ActionServlet) will select an appropriate Action for each request, create an instance (if necessary), and call the perform method." I have working Actions getting data from my client and populating the ActionForms, but now that I'm adding a session bean, how do I do what's explained above. What I'm needing the servlet for is to have the init() method of the Servlet initiate my session context.According to the Action class docs, I need to have an ActionServlet call the appropriate Actions. Any examples Any help much appreciated.
Re: ActionServlets calling Actions
I thought the Action class I've been using was the controller as it returns several different jsp's depending upon the outcome the population of ActionForms. I have a very simple example going, jsp's that use Action's in the form method tag. Is this not considered the controller? I think this is my point of confusion. I'm trying to figure out what's meant in the Action api, which states "The controller (ActionServlet) will select an appropriate Action for each request, create an instance (if necessary), and call the perform method." Do I need to create an ActionServlet (which will be the controller)? How does that then select an appropriate Action, any examples anywheres? And then, maybe anyone have examples of how session beans are tied in to all this. - Original Message - From: "Craig R.

I'm not sure quite what you are referring to when you say "what's explained above". The sentence you quoted is done by the controller servlet on each request. What I'm needing the servlet for is to have the init() method of the Servlet initiate my session context.According to the Action class docs, I need to have an ActionServlet call the appropriate Actions. Any examples The init() method of the servlet is not the right place to initialize a session. That is because init() is called only when the web application itself is first started (and then it's called only once). You would use the init() method to set up *application* scope things, rather than *session* scope things. In a servlet 2.2 environment, the best place to set up session stuff is in the Action that handles your login. For example, the example application does this (LogonAction) to create a User bean in session scope, once the user has been logged on successfully. Any help much appreciated. Craig
Actions and Session Beans
I've finally got struts taglibs and a few Actions working in my jsp pages, but I'd like to be able to populate some EJB's with the model data from the ActionForms. I'm not sure how to do this. I've got a session bean which operates on an entity bean which I will then send to another machines java app, but I'm not sure how to implement the session bean in my Action. Anyone know of examples or where I may find some refs on doing this?
init'ing session beans in an Action
I finally have my struts tags working. Next step. My app has jsp pages that populate ActionForms. I now have to populate my entity beans, but one step at a time, so I'm trying to instantiate session beans from my Action classes (which will later operate on the entity beans) and I'm not sure how this is done. I thought that the JNDI init context stuff would go in the init() method of a servlet, but with Actions, not sure if this is correct as I couldnt' override the init() method. Or should my action class be extending from ActionServlet instead of Action? Any help much appreciated.
Re: getter methods ...
Thanxs, I thought it was supposed to be the same case as what was in the getter method. Thnxs again. - Original Message - From: "Matthew O'Haire" [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Tuesday, March 20, 2001 9:56 PM Subject: RE: getter methods ... Hi, I think the culprit is in your JSP.. html:radio property="View" value="Master View" The property names are case-sensitive. Try property="view".
a simple struts test
Should my struts-config.xml have to be configured if I'm just testing to see ifI can get struts working w/ Orion. I've been having trouble getting struts working with orion 1.4.5. I've done everything the struts docs have said for the install and taken out all struts*.tld's from the struts.jar (removed, andwhich is in my WEB-INF/lib dir) and put them in theWEB-INF dir. Made the correct entries to web.xml. So I think I've got everything needed for a basic test of jsp's w/ a very simple config. I'm wondering if I need to do the controller, config files,etc.. for a simple test like this. %@ page language="java" %%@ taglib uri="/WEB-INF/struts-bean.tld" prefix="bean" %%@ taglib uri="/WEB-INF/struts-html.tld" prefix="html" % html:htmlheadtitle bean:message key="main.title" //title/head bodyhtml:errors / This is a atest./body/html:html Any help much appreciated.
how does a jsp find the resource file
I've been following the examples trying to get struts working w/ orion. When I go to a url like http://localhost/cais/index.jsp, I expect the following jsp test page to show up. But since it's mapped to the action servlet in the web.xml file (below), and since the jsp page has no reference to a servlet, how does it know where to find the resource properties file that's in the web.xml? - index.jsp - %@ page language="java" % %@ taglib uri="/WEB-INF/struts-bean.tld" prefix="bean" % %@ taglib uri="/WEB-INF/struts-html.tld" prefix="html" % html:html head title bean:message key="main.title" / /title /head body html:errors / This is a atest. /body /html:html - web.xml - The mapping in the ~/WEB-INF/web.xml file has the following entry: servlet servlet-nameaction/servlet-name servlet-class org.apache.struts.action.ActionServlet /servlet-class init-param param-nameapplication/param-name param-valuecom.neuroquest.cais.resources.cais/param-value /init-param /servlet - I have a file called cais.properties within the com/neuroquest/cais/resource directory.
