Learning JBoss and XDoclet

[asahni]

I am writing guide titled Start using JBoss with XDoclet, which can be downloaded from
http://www.mycgiserver.com/~asahni/
Please send me any comments for its improvement

Some of people experienced problem in accessing early URL they can try from alternative URL of my home page.

Having a CMR section would be nice. I have been playing with it for a while but it could have been better with a tutorial.

Hi asahni,

I have started a collection of helpful beginner links in the thread "How to get started?" http://www.jboss.org/modules/bb/index.html?module=bb&op=viewtopic&t=forums/ Don't want you add your link to this thread?

I have made some changes in guide based on user feedback. Now it covers the following
-Basic setup of JBoss application server
-Setup of XDoclet
-First web application.
-First session bean.
-First CMP bean.
-First use of JMS as resource
-First MDB
-First Mail

You can download it from my home page

Good luck for JBoss learning.

I'm having problems with the example for a stateless EJB. I changed the build.xml file (which would not complete) fileset line to:





This allows a war file to be created an copied to jboss. But when I run the jsp page (FirstSession) I get the following error. How can I fix this?

[asahni]

Thanks for bringing error. Please change the import in FirstSession.jsp from test.ejb.* to com.helplab. The page dirctive be :
<%@ page language="java" import="javax.naming.InitialContext,java.util.*,com.helplab.*"%>

I checked the corrected code.

Arun,

Thank you for posting this helpful guide.
I failed on running your first session bean sample through JBoss after successfully compiled and deployed. I got the following Linkage error:

Do you have any idea how this happened and how to pass it?

Thank you.

I am not sure what is the problem in your setup. I do not have problem in running examples with JBoss+Tomcat. Are you able to run any JSP page in your setup? Are you abel to deploy any other session bean in your setup?

[asahni]

It is not happening on my setup with JBoss and Tomcat bundle. I am not sure about cause of problem. Are you able to run any other WAR application with JSP? What is the error on console when you deploy session bean?

[mzaremba]

Hi,

I cannot build your "first" example. Below is stack error that I am getting. Do you know the reason.

Thanks for feedback. I have made changes in pdf and checked correct code with it. This time I have included tested build files for direct deployment in server.
Happy JBossing.
