[jboss-user] Debug EJB3 component

Hello, everybody.

I am developing web-application that needs to access EJB3 component that 
is deployed to JBoss AS.
This bean uses few 3rd party libs, that are packed into the same jar as 
bean is, under "/lib" path.
In the JBoss console i see message:

[EJBContainer] STARTED EJB: nuntia.ejb.CRFacadeBean ejbName: CRFacadeBean


So, it looks like bean is deployed successfully.
 From web-app (from struts action actually) i try to get bean instance 
as follows:

Properties properties = new Properties();
properties.setProperty("java.naming.factory.initial", 
"org.jnp.interfaces.NamingContextFactory");
properties.setProperty("java.naming.factory.url.pkgs", 
"org.jboss.naming:org.jnp.interfaces");
properties.setProperty("java.naming.provider.url", "localhost:1099");
CRFacade crFacade = (CRFacade) new 
InitialContext(properties).lookup("CRFacadeBean/local");

Here, CRFacade is @Local interface, and CRFacadeBean is an 
implementation class (@Stateless bean).

Instance seems to be successfully created (i see that while debugging), 
but as soon as first of its methods is called, i got an 
InvocationTargetException:

[PropertiesFactoryBean] Loading properties file from class path resource 
[alfresco/domain/hibernate-cfg.properties]

So it seems that there's some problem either in bean or in the way how 
libs are loaded (PropertiesFactoryBean class is actually part of 
spring.jar that is one of the libs i'm bundling with my bean's jar). 
Note, that class does his job well when used standalone (not as bean). 
So, i would like to debug bean to find out what the reason of failure 
is. I'm using Eclipse and JBossIDE, my project is configured properly, 
sources are attached to the classes, and i can navigate throuhg them, 
but still, i can't catch breakpoint that is set in the body of 
constructor of my bean, so it seems like debugging is not working this 
way...

And, finally, questions:

1) do i pack/deploy my EJB3 component correctly?
2) is there any way to debug deployed EJB3 component?

P.S. I am new to EJB3, so sorry for dumb questions (if any) ;)

Thanks in advance!

Cheers,
R. Kasianenko
