Spring roo is new framework and I found it very interesting. I have been working on web application for last 3-4 years and Always found JSPs are hard to maintain across teams if everyone is not disciplined enough about separation of markup and serverside logic. I have used JackBe/BackBase in last projects and I enjoyed xml templates working as views. This was much better than JSPs. But I couldnt automate webtests through selenium for backbase.

I would be surely using Spring MVC (-view), Hibernate on the backend. I found Wicket as good alternative. Have you used wicket along with Spring and what was your experience?
