Hi, This is a general question. Can I use SQLJ with JBoss? Specifically, can I create SQLJ DefaultContext using a connection created from JBoss DataSource and use it to perfoem SQLJ statements? Is it too much overhead because I suppose to close the connection after each usage in EJB, which implies that I have to create DefaultContext each time I get a connection. Another issue is the potential conflict of transaction management between JBoss and SQLJ. I prefer to have JBoss, not SQLJ, to handle all the transactions.
