SQLException: Transaction is no longer active (status = Committed).

Question

I am using TopLink 9.0.3 with a set of stateless session beans running in Weblogic 6.1 hitting an Oracle 8.x database. I am using the recommended approach for using the external trancaction controller but I am seeing the following errors when calling a method on a session bean that persists an object:
UnitOfWork(2028166)--JTS#beforeCompletion()
UnitOfWork(2028166)--#executeQuery(DataReadQuery())
UnitOfWork(2028166)--SELECT SEQUENCE_NUMBER.NEXTVAL FROM DUAL
UnitOfWork(2028166)--#reconnecting to external connection pool
UnitOfWork(2028166)--EXCEPTION [TOPLINK-4002] (TopLink - 9.0.3 (Build 423)): oracle.toplink.exceptions.DatabaseException
EXCEPTION DESCRIPTION: java.sql.SQLException: The transaction is no longer active (status = Committed). No further JDBC access is allowed within this transaction.
INTERNAL EXCEPTION: java.sql.SQLException: The transaction is no longer active (status = Committed). No further JDBC access is allowed within this transaction.
Strangely enough, this session bean method call works the first time it's called but then fails when I call it the second time. It seems there may be some issue with the transaction listener:
--------------- nested within: ------------------

INTERNAL EXCEPTION: java.sql.SQLException: The transaction is no longer active (status = Committed). No further JDBC access is allowed within this transaction.
It seems that TopLink is referencing then old transaction. Has anyone seen this issue? Any ideas?

Hello Darcy,
I'm not exactly sure what is happening and think that a lot more information would be required, so technical support might be your best bet.
My guess would be that your sessionbean method is hitting an exception in user code that is triggering the transaction to be marked for rollback, and thus not allow any SQL execution. Try putting a try/catch/debug statements in your sessionbean method to find out if any exception are occurring.
Otherwise more information such as,
- the complete exception stack trace
- how are you configuring your session, external connection pooling, which transaction controller, etc., does it work with normal connection pooling
- what exactly is the sessionbean doing
- when exactly does the problem occur, are there concurrent process, etc.
