Hi guys.

I have a weblogic problem for about a week.
So, i have an EAR with a EJB and other module (business logic, etc).
In my EJB I need to recover a reference of an implementation.
I'm using getBeanFactory().getBean(BEAN_NAME); in onEjbCreate, I have an .xml file with the bean definition to my implementation class.
I've did many tests, and my getBean work fine.
The problem is when I'm trying to execute a method from my implementation class. Error:
Exception in thread "main" java.rmi.RemoteException: EJB Exception: ; nested exception is:
at weblogic.rjvm.ResponseImpl.unmarshalReturn(
at weblogic.rmi.cluster.ClusterableRemoteRef.invoke(
at weblogic.rmi.cluster.ClusterableRemoteRef.invoke(
at Source)
Caused by: java.lang.NullPointerException

The implementation class is PatientServiceImpl. This class is in a jar in the EAR.
Just for the test, I've put the implementation class in the same project as the ejb, and no error.
If it is in another project I have this error.
I've done many tests and I think that maybe the implementation class nees some jar, or something, but I don't knwo what.
The problem is that I cannot see too much error, only the error posted.
For the test, I've put all jars in webloggic classpath, and the same error.

I don't know what else to try.
