A surprising exception when call the EJB

Question

OS:Windows-2000
J2EE-Server:J2sdkee1.2.1

The CMP-bean---UserEJB has been deployed successfully.
Main client program:
UserHome userHome=(UserHome)PortableRemoteObject.narrow(objectRef,ejb.UserHome.class);
User user=userHome.create(userid,password,name);
When running the client program,exception occured like this:---
java.rmi.ServerException: RemoteException occurred in server thread; nested exce
ption is:
java.rmi.RemoteException: Transaction aborted (possibly due to transacti
on time out).; nested exception is:
javax.transaction.RollbackException
java.rmi.RemoteException: Transaction aborted (possibly due to transaction time
out).; nested exception is:
javax.transaction.RollbackException
javax.transaction.RollbackException
<<no stack trace available>>
But a new data-row has been inserted into the table successfully.
What on earth caused that? And how to solve this problem?
Any reply is welcome.Thanks!

I have only a partial solution (if you find it all I'll be happy to know myself...)
I had the same problem. It occurs that the problem is related to the definitions of transactions attributes in the table of the transaction tab. go to this tab and change the attribute from "required" to "supported" (I assume you have "required" and it should not be) in the method which causes the exception.
hope this helped.
