Deploying two EARs in same JBoss

[vikash_sharma]

Hi,
I have a requirement to deploy two EARs in the same JBoss environment which have some common libraries and one ear can look for ejb deployed in second one. My JBoss is Jboss 3.2.1 tomcat version. If I deploy both of them as it is, then when the lookup happens it gives DuplicateClass exceptions for common library classes because Jboss searches in all ear's libraries.
I read that if I put a separate loader repository in jboss-app.xml then this can be resolved. I tried that by putting following snippets in my jboss-app.xml for both ears
<jboss-app>
<loader-repository>
utils:service=LoaderRepository
</loader-repository>
</jboss-app>

Now when the first ear's ejb's is looked up for a home, it returns null.

I am not sure about the syntax for loader repository and what it expects here.

Please help me in finding the correct way to achieve my deployment model.

Thanking in advance,
Regards,
Vikash

I forgot to add the stacktrace. The home is not null but when it is trying to create it is throwing null pointer exception
