Hello all.

I am try retreive java.sql.Connection in Eclipselink Application running on glassfish.

Connection cnn = ((JpaEntityManager)em.getDelegate()).getServerSession().getAccessor().getConnection();
Connection cnn = ((EntityManagerImpl)(em.getDelegate())).getServerSession().getAccessor().getConnection();
Connection cnn = (Connection) em.unwrap(java.sql.Connection.class);

But in all cases i get cnn == null.

Netbeanse/Ecelipselink v 2.3.3.
