I just want to say, Seam is pretty damn amazing. It finally makes web development right by letting us use correct object-oriented design, and have that link in with persistence and web presentation in a sane way. No more Servlets, no more messy JSP. I put all my constraints right into my entity classes, where they should be. I write no more SQL. I never look at a HttpServletRequest again. Getting everything set up and working was a big challenge. One little mistake somewhere and there's an exception that doesn't tell you what's wrong. But once it's going, it's quite a powerful tool.
