If you don't need EJBs (and who would, I've always steered clear from them and never regretted it), than don't worry about it. In the unlikely case you ever do, just address it then by swapping out your app server. Write your software generically enough so that you don't depend on a single one. If you know you need MQ and you want management of it integrated in your application server, JBoss is worth considering. Also look at Glassfish while you're at it.
