You don't need to use the Arjuna Transactional Driver. This is the point of JCA, we do this for you. Your lookup would be: | | InitialContext ctx = new InitialContext(); | DataSource ds = (DataSource)ctx.looking("java:/BasicService01DS"); | Connection conn = ds.getConnection() | | JCA handles transaction enlistment for you so there is no need for a special wrapper in this case.
