[news.eclipse.tools] Debugging JBoss with Eclipse question

[Rick Horowitz <rickhoro@xxxxxxxxxxxxx>]

I am trying to run JBoss in the Eclipse debugger so that I can 
single-step through the JBoss code (in addition to client and EJB bean 
code).

My Setup:
=========

Eclipse 2.1m4 on Redhat 8.0.

1. I created an Eclipse project called "org.jboss". In this project, I 
have added no source files, but have added the following external JARs:

<jboss-install-dir>/bin/run.jar
<jboss-install-dir>/bin/jboss-boot.jar
<jboss-install-dir>/bin/jboss-common.jar
<jboss-install-dir>/bin/jboss-jmx.jar
<jboss-install-dir>/bin/jboss-system.jar

I then created a ZIP file containing all of the sources in JBoss and 
attached it to each of the above JAR files.

2. I configured a Java Application Launcher in Eclipse with the 
following params:

Project: org.jboss
Main class: org.jboss.Main

Working Directory: <jboss-install-dir>/bin

Classpath: <jboss-install-dir>/bin/run.jar
   Note: I removed the other JBoss JARs from the classpath because 
otherwise they interfere with the JBoss classloader architecture.

My Problem:
============
When I launch the application in the debugger with a breakpoint in 
org.jboss.Main.main(), Eclipse displays the source file and I can debug 
normally, single-stepping, etc. I can single-step up to the method: 
org.jboss.Main.boot(), at the line, "server.init(props)".

When I step into server.init() in the debugger, the source file for 
org.jboss.system.server.ServerImpl is not found by the debugger, even 
though I can open that file in the Java perspective or the Plugin 
Perspective and view/edit the source.

Hint:
=====

JBoss loads the org.jboss.system.server.ServerImpl class in a new 
URLClassLoader, a different classloader than the boot classloader in 
which the application is started. Could this be the problem?

Question:
=========

Why is the org.jboss.system.server.ServerImpl source file not found by 
the Eclipse debugger?

Thanks for any help,

Rick
