Hey, I'm in the process of designing a client/server application which does some pretty basic stuff. It allows users to create/update their profiles, check other users profiles, chat with other users and chat with multiple users in a sort of a chat room. I'm planning to do the server side in Java and was wondering if there is any open source code I can integrate into it. I was thinking of using a RESTful solution, so if you know something I might be able to use I'd be glad to hear about it. Thanks.
