Example 1
@Override
public Transaction beginTransaction() {
	checkOpen();

	Transaction result = getTransaction();
	result.begin();

	return result;
}
 
Example 2
public Transaction beginTransaction() throws HibernateException {
	errorIfClosed();
	if ( rootSession != null ) {
		// todo : should seriously consider not allowing a txn to begin from a child session
		//      can always route the request to the root session...
		log.warn( "Transaction started on non-root session" );
	}
	Transaction result = getTransaction();
	result.begin();
	return result;
}
