I am new to Java gaming enviroment, so any pointer would be helpfull. Below I describe what I've in mind.

At the moment I am thinking to build a simple 2D racing games (just view from the top), but it must have additional features such as it can support multiplayer games. The idea is that 2 clients on 2 different computers can play on the same race track.

What I've in mind is bulding them using Java Swing and draw the track + the car (obviouslly from images) and add manually the collusion detection (using if statement). For the network part, I am planning to send the information (regarding the X,Y coordinates of the car) to the server, and the server broadcast it (perhaps using Java RMI/CORBRA).

I haven't look at the existing java library, I was wondering whether lookiing at the existing java code library would be much better in my case?
If yes, then can you pointing out which library should I look?
