Hi Wes,

I am working Jpa Toplink using spring, I have one req for batchupdate, for
this batchupdate i am using the preparedstatement, for this i need the
connection. with out spring its working fine but while integrating with this
connection coming null.

pstmt1 = connection.prepareStatement(query);

connection = ((oracle.toplink.essentials.ejb.cmp3.EntityManager)
entityManager)
					.getServerSession().getDefaultConnectionPool()
					.acquireConnection().getConnection();

this connection coming null, with out spring this connection working fine.

So please provide the solution for fetching the connection.
