Subject Re: @MappedSuperClass Cause Null Pointer Exception in Class With IdClass
Date Tue, 19 May 2009 10:08:08 GMT

Hello
I am using OpenJPA 2.0 SNAPSHOT but it seems that the problem still exists

Here is the stack trace of exception thrown. The test case succeeded without
IdClass and using Embedded id but IdClass has problem.

javax.ejb.EJBException: The bean encountered a non-application exception.;
nested exception is: 
	javax.ejb.EJBTransactionRolledbackException: The transaction has been
marked rollback only because the bean encountered a non-application
exception :org.apache.openjpa.persistence.PersistenceException : null
