Cross-platform socket communication

Question:
I am writing a server written in Java that needs to take input from a game written in Visual Basic and sends the output to clients on the Internet. I'm having a really hard time getting data from a socket connection initiated from the VB code (standard Winsock OCX). What type of InputStream would handle this type of cross-platform socket communication best?

Answer:
The type of InputSream you use will depend heavily on the data representation used in your program's communication protocol. More than likely, you will have to use the InputStream you obtained from your Socket and perhaps wrap it with a BufferedInputStream. Then you will have to read the bytes and do whatever conversion might be necessary to Java primitives. This is why many Internet protocols use ASCII text messages as the underlying representation for their communications.
