EJBTransactionRolledbackException with getCausedByException() null

Question

Hi,
I'm using Jdeveloper11 with ADF/EJB.
On my EJB, I'm throwing a RuntimeException("message").
When the UI (or in fact, even the EJB Interceptor) is catching any exceptions, the only exception there is EJBTransactionRolledbackException with no getCause() or getCausedByException().
They are both null.
So, basically, I'm unable to trap simple errors and display only the messages on the UI later. It's actually displaying the whole exception.getMessage, which is something like:
Exception: ; nested exception is: javax.ejb.EJBTransactionRolledbackException: EJB Exception: ; nested exception is: java.lang.RuntimeException: "message here"
What I need to do is actually only display the "message here" part on the UI not this whole thing.
Session bean code is below:
@Stateless(name = "FilingService", mappedName = "FilingSystem")
@Interceptors(ServiceInterceptor.class)
@TransactionAttribute(value = TransactionAttributeType.REQUIRED)
public class FilingService implements FilingServiceLocal, FilingServiceRemote
<snip>
public List<FilingEntity> queryFilingFindAll(final int... rowStartIdxAndCount)
List<FilingEntity> list = filingMaintenance.queryEntityFindAll(rowStartIdxAndCount);
Collections.sort(list, new FilingEntitySorter() );
return list;
// service interceptor code:
public class ServiceInterceptor
@AroundInvoke
public Object businessServiceInterceptor(final InvocationContext invocation) throws Exception
Object obj = null;
try
obj = invocation.proceed();
catch (EJBTransactionRolledbackException exc)
System.err.println("got EJB exception" + exc.getMessage());
System.err.println("cause by: " + exc.getCausedByException());
System.err.println("cause: " + exc.getCause());
return obj;
Thanks for any help
