Enterprise developer using Jersey to make RESTful apps here. I've come from a Django background in my own time, and while it's pretty verbose you can get a lot done with Jersey and spring-wiring things. Are there any complementary tools out there for things like templating and form validation? We're currently using Apache Velocity for templating and manually doing this stuff feels a bit alien to me when Django gives you this stuff for free.
