Right on the ball.  I played around with Cocoon, but gave up on it eventually.  I find Java still good for server works, but found JSP and Struts to be inappropriate for a lot of applications.  I now discourage my clients from using Java if they don't have a significant Java resources already in place.  Dolts who read a few Java books and passed Java certification tests don't qualify as significant Java resources.  For most applications, going with PHP or Python will get you the same thing for a lot cheaper to create and evolve.  I am warming up to ASP.NET as well.
