I'm trying to write a GUI in JAVA, using SWING, and I will need this GUI to communicate with C++ client code (probably through a Scheme interface if Java and C++ cannot communicate directly) and with a 3D graphics rendering program, probably Open Inventor. Could someone please direct me to a place where I can find information on how to get interprocess communications (sockets and pipes) going between Java and scheme and/or C++? I would really appreciate any help you can give.
