I'm using your jta session service and it was working most of the time. 
but now I'm seeing a strange exception:

As you can see, some of the hibernate calls are working, but then 
hibernate claims: "Session is currently disconnected". The transaction 
is active. the session was obtained from the service just before the 
invocation of load. 
 
what exactly is happening? the thread goes through the following 
arrangement of transacted methods: 
 
NEVER process { 
  NEVER execute { 
    REQUIRED checkPrecondition { 
    } 
 
    REQUIRES NEW executeAsynchronously { 
      REQUIRED enlist { 
        REQUIRED checkPrecondition { 
        } 
 
        REQUIRED initiate { 
          REQUIRED load { 
            net.sf.hibernate.HibernateException: Session is currently 
disconnected 
          } 
        } 
      } 
    } 
  } 
}
