So until you have some very strong reasons to go for EJB, dont! In my limited knowledge , Spring with Hibernate or Ibatis, is a good substitute for EJB, if you want EJB features, without paying for the expense of remote look up, or you can use EJB with local interfaces (I believe that using local instead of remote removes a big performance overhead).

Unfortunately, I still haven't been able to get cooking on this project, as it
still seems to be not working. I had wanted to verify that I understood what I
had read. In any case, can anyone tell me what is wrong with the following JSP?
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"; %>
Test Page
<% String test = "This is a test String."; %>
${test}
This should print out "This is a test String" twice, correct? Do I have to
place the String in the request?

Re: Hi-New to this group
Maya, You mentioned that you are providing access to things in the users database. Are you giving them write access? If not there is little reason to use Entity Beans (read None) in your application. If you don't need your application to be distributed, and I didn't see it in your requirements, then session beans may be overkill too. I would look to what others have said here and evaluate hibernate or naked JDBC before choosing entity beans as your backend and session beans as your business facade. (though I wouldn't write off session beans entirely). Using something like a command pattern could work nicely as a business facade. I am working right now with an application that uses a command pattern for the business layer and I am quite fond of it. You could also have a look at the Commons-Chain project for a nice implementation of a pattern that is quickly becoming one of my favorites. http://jakarta.apache.org/commons/chain And beginning with struts 1.3 it will be a first class citizen of Struts.

Heh, you are using EJB and complaining about time consuming layers? :-) A delegate layer will probably cost 10% of the time you need to EJBize your business logic (the more effort of writing ejbs instead of POJOs). It will probably save you enough days in one year, when you refactor your application to remove ejb dependencies, so you can get a week more off :-) The ultimate solution would be to use/write a generator, which generates you an abstraction layer on top of ejb from java interfaces or xml. If you decide to get rid of the ejbs, simply change the generator to generate whatever you want, and be fine :-) Regards Leon > > You wrote: > >A quick and dirty fix to your problem would be to declare > the execute() > >method in your action to also throw a RemoteException > > There no need for that - RemoteException is a subclass of > Exception and decleratively adding it to the > section works fine (no need to change the > methods signature). > > Thanks > Rivka > > -Original Message- > From: Ed Griebel [mailto:[EMAIL PROTECTED] > Sent: Wednesday, July 20, 2005 3:19 PM > To: Struts Users Mailing List > Subject: Re: ApplicationException sample > > Rivka- > > Since you're developing from scratch, you might want to put a > layer in-between your EJBs and Struts.

Session Beans are absolute performance killers, and a huge ressource eater. And I think the proper question is not "why to avoid session beans" but "why use session beans in this application".

Re: ApplicationException sample
I think a good example of the manager classes are in the sample Struts-based application generated by AppFuse: https://appfuse.dev.java.net/. I have yet to see the full benefits of these manager classes, however I am currently attributing this to my general newbieness with Java web applications. Glen [EMAIL PROTECTED] escribió: Rivka, I'll add to this: Pick up "Core J2EE Patterns" from Sun. It is worth the money and will help you. My solution would be similar to what Ed said. I would use a "manager" class (aka "business facade", "business delegate", "service manager", etc. although each one of these may mean something slightly different) to decouple Struts from your EJB layer. Struts actions talk to the manager only. The manager methods (typically logon + C.R.U.D. + search -- general user actions) throw SystemException and ApplicationException only. Struts is configured to handle these (or subclasses of these) declaratively (or else try/catch for these two in your Action class if you haven't gone declarative yet). Struts then knows nothing about RemoteException and other specific Exceptions like that. It only has to worry about two Exception types (but can go finer grained by handling subclasses of these when you are ready). Meanwhile your manager class (or some data access object/manager behind the main manager) handles try/catch for RemoteException, EJB Exception, etc. If manager cannot do his job , he either throws SystemException or ApplicationException at the "user" (Struts).

Re: Hi-New to this group
Also I will add that the last time I developed (part of ) an application like yours, the main performance barrier (in my environment at least) was not marshalling data across the network. It was by far multiple (often redundant) database accesses per user request. I would suggest you look into caching strategies somewhere in that middle layer.

RE: TilesRequestProcessor is executed twice
Ronnie, Here is what I see: you have two traces that both invoke your Action.execute() with one call (each) from the TilesRequestProcessor. Since your trace doesn't show two calls to the Tiles Request Processor, that suggests your browser is submitting twice. The question is why is it different when you have a Tile listed as your success/error ActionForward. To help debug this, can you show us: 1) Your form's declaration tag (especially any onclick declarations). 2) Any submit buttons (both HTML the browser sees and from the JSP page) you use in that form with any onclick="..." declarations so we can be sure it isn't performing a submit calls from a submit button resulting in some sort of double submit such as you saw? 3) Your Action and forward definitions for both the tile use and the direct JSP use. For example, are you adding 'redirect="true"' to your forward when you are using a JSP so the browser redirects externally to the JSP or with it as false so it performs an internal submit so the browser never knows the true destination/JSP-page?

I'd say both, javascript for a nice user experience and server side for safety. One because as a matter of good practice you should never trust anything to have been properly validated on the browser and two because testing the number of characters in textareas can be error prone. I forget which one but either Mozilla or IE has given me length counts in javascript which differ from the String length by the time the value is one the server - basically a CR versus CR/LF issue.

Yep. If you use nested business object, you can easily clean the action form after you finish or cancel your wizard just by setting reference to null.

Re: ApplicationException sample
Rivka, I'll add to this: Pick up "Core J2EE Patterns" from Sun. It is worth the money and will help you. My solution would be similar to what Ed said. I would use a "manager" class (aka "business facade", "business delegate", "service manager", etc. although each one of these may mean something slightly different) to decouple Struts from your EJB layer. Struts actions talk to the manager only. The manager methods (typically logon + C.R.U.D. + search -- general user actions) throw SystemException and ApplicationException only. Struts is configured to handle these (or subclasses of these) declaratively (or else try/catch for these two in your Action class if you haven't gone declarative yet). Struts then knows nothing about RemoteException and other specific Exceptions like that. It only has to worry about two Exception types (but can go finer grained by handling subclasses of these when you are ready). Meanwhile your manager class (or some data access object/manager behind the main manager) handles try/catch for RemoteException, EJB Exception, etc. If manager cannot do his job, he either throws SystemException or ApplicationException at the "user" (Struts).

Re: Validation is called before form is populated from my database
Finally, I found two valuable solutions to my problem.
The first one is MappingDispatchAction, as suggested
by Hubert. It is efficient but I dislike to have so
much entries in my struts-config (my application is
going big enough)
I found a good explanation for it by the frustrated
programmer (who gives us some remarks about Struts
which were helpful for me)
http://frustratedprogrammer.blogspot.com/2004/07/struts-121-mappingdispatchaction.html
The second one is to redefine the methode "validate"
in my form-bean (EditionPersonneForm, which extends
validator.ValidateForm) and add a condition in it,
which enables validation or not, according to my
dispatch parameter "do".
public ActionErrors validate(ActionMapping mapping,
javax.servlet.http.HttpServletRequest request)
{
if (someCondition)
{
return new ActionErrors();
}
return super.validate(mapping, request);
}
Thanks again, Hubert !

Re: instantiation of actionforms in session scope
[EMAIL PROTECTED] schrieb:
In the case you outlined, wizardForm should be placed into the session
scope when leaving the Funds action.
Shouldn't it be in the session scope by specifying
scope="session" in the action tags in the struts-config.xml?
You are not required to use the
struts tags to access the data, but if you are using the struts html
tags for input etc, you will need to use the html:form tag. If you are
not using the struts tags, you should still be able to use the form bean
with a standard You should
also be able to access it from other action classes by explicitly
calling the getAttribute("wizardForm"). When you say that it is
instantiated with every new page, how are you attempting to access the bean?
I use the bean in several pages. The idea is to have something like
a wizard. On every page a part of data gets added to the wizard bean.
Action.execute() provides a ActionForm parameter. By using this
parameter I access the bean.
What happens is that the bean gets created, filled with the parameters
from the request. In the action class I can access it (and I see
the filled in values on the next page). On the following page a new
formular gets filled. Then the bean gets created again, and filled
with the new parameters. The values from the last page are lost.
Now a possible workaround would be to copy the data from the bean
to some wizard-object which I put in session-scope manually. But
I would like to have a workaround-free solution.
I thought, the supposed behavior is that a bean declared to be within
session-scope lives within the session as long as the session lives.
And if it doesn't exist, it gets created by the struts-framework.
Am I wrong?
I mapped the same bean to several actions in the struts-config.xml:

I've checked that and than again, the right bean gets filled with the
right parameters from the request, so I think the problem isn't the
configuration. The problem arises on the following pages, where I need
the data to, but the bean gets instantiated with every new page again.

Re: ApplicationException sample
Rivka- Since you're developing from scratch, you might want to put a layer in-between your EJBs and Struts. Some will call it business logic, data access object (DAO), or Helper classes. This allows you to separate the struts-related concerns from business-related concerns. It also solves the issue you mentioned about where to catch RemoteExceptions. Also, these helper classes can be used in more than one action which could be a benefit. A quick and dirty fix to your problem would be to declare the execute() method in your action to also throw a RemoteException, and then declaratively handle the exception in your Struts config inside . I'd only use this if there's no way for you to recover the transaction when a remoteException occurs. It's an old article, but take a look at http://www.onjava.com/pub/a/onjava/2002/10/30/jakarta.html. These sites are good for starting out in struts too: http://husted.com/struts/ and http://www.reumann.net/struts/main.do Good luck, -ed On 7/20/05, Rivka Shisman <[EMAIL PROTECTED]> wrote: > > Erik, Glen, Laurie - Thanks for your help > > After doing some more homework about exception handling - I have another > question: > > If my Sturts Action calls directly to EJB methods (with no delegate > Layer) - then I have to catch RemoteException for all runtime > exceptions?
