Does BlueJ support Networking? Can you have the main() of Client.java and Server.java running at same time? I always get this "Your program is running.You cannot start another execution......". Any help would be greatly appreciated.
I am not getting the same error you are, but my simple TCP client/server program does not work in a single instance of BlueJ. However, if I run BlueJ twice, then I can run the server in one instance and the client in the other and that works.
