I am considering learning some server side stuff with java, however I am getting mixed views and opinions when searching. I read a benchmark that claims java has superior performance than most alternatives, and I was considering taking a look at grizzly or spring, but I really don't know too much about these frameworks.. Can someone please shed some light, and provide some advice for a novice?
p.s can you provide some information about documentation/tutorial quality and ease of use.
Much appreciated!
