Oh well, problem solved. Thanks for the pointers.
I had in my main method:
GameKeeperRemoteServer server = new GameKeeperRemoteServer();
Naming.rebind("//localhost:" + port + "/GamekeeperRemoteServer",
server);
So it appears that after the main method had completed, after a certain
amount of time, the Gc killed the object, which is odd, because I assumed it
wouldnt as "Naming.rebind" has a reference to it. I simply made the 'server'
variable global and static, and it works fine.
Cheers,
