Context c = new InitialContext();
Object obj = c.lookup("java:comp/env/XPCDataSource");
DataSource ds = (DataSource)narrow(obj, DataSource.class);
connection = ds.getConnection();

//context is javax.ejb.SessionContext

//Transaction should be getten from EJB

UserTransaction tx = context.getUserTransaction();
