In the MDB onMessage() you would need to have | onMessage(...){ | InitialContext context = new InitialContext(); | DataSource ds ; | if(condition1) | ds=(DataSource)context.lookup("ds1"); | else if(condition2) | ds=(DataSource)context.lookup("ds1"); | ...................... | } | You finally made me help in DOING Code for you :( View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4082063#...
