I'm curious if there is a good Swing framework (or maybe better put a good client/server communication framework) out there that can be used when developing fat Swing clients to communicate to backend server applications. At this point I think going to J2EE would be a bit of an overkill for this project, but I'm up for suggestions. High-level basic client requirements include querying the server for data and receiving event notifications (such as updates to the data). I'd like to maintain the MVC pattern as much as possible. And yes, I would like to maintain the Swing interface.
I've used RMI before (with callbacks) and I'm wondering if that's the best approach. JMS?
FYI, it's an open-source project I'm working on when time permits.
