2 Tranaction id's created for consequent webservice operation under a single User Transaction

While invoking 2 webservice operations with in a UserTransaction, I see there are 2 different transactions created.

The client invocation of the service looks like :

ut.begin();
simple.client.SimpleWebservice port = service.getSimpleWebservicePort();
out.println("Transaction id at server"+port.getId());
out.println(port.mandatory("test"));
ut.rollback();

Each of the out.println in the servlet prints the obtained globalTransactionId from xid of the XAResourceImpl.
#### Environment
glassfish 3.1

Start by reproducing the client sequence shown: begin one UserTransaction, invoke getId and mandatory on the webservice port, then roll back. Inspect the servlet output and the globalTransactionId obtained from xid of XAResourceImpl; the issue is resolved when both operations report the same transaction ID under one UserTransaction.
