RESTful Web Services

implementations:

Sun's Jersey
Restlet
RESTEasy
Struts + REST plugin

personal favourite so far - Jersey
unfortunately Google App Engine supports Restlet, so ... I have to use it.

Wicket + Google App Engine

Back to Wicket, totally disappointed from Spring

I really don't understand why Spring is so popular... absolutely useless
