EJB Entity/Session Transaction

[agodoy]

I am getting an error from a Session EJB trying to update two distinct Entity EJB's. From the session bean I open a transaction and create two entity objects. But immediately after trying to create the first one I get the following message:

com.evermind.server.rmi.OrionRemoteException: Error allocating db connection: java.sql.SQLException: Calling setAutoCommit(true) on a Connection is not allowed during a global transaction.; nested exception is: java.sql.SQLException: Calling setAutoCommit(true) on a Connection is not allowed during a global transaction.
