One of my fellow researchers (a C/C++ developer) was assigned to design a protocol and because he is a C programmer he designed something which is hard to implement in other languages which we need (VB, php, Java, C#).

If it had built something like SMTP and HTTP protocol (where even numbers are transferred in string format) it could be easily implemented. However he has used C structures.

1) Now the problem is that how can I create such commands (which contain binary coded numbers with different lengths) in Java?

2) What primitive data types I should use for 8bit and 32bit unsigned data types (in a way that later a C program does not have problem interpreting them as normal C data types)?

Thank you for your help.

You should have no problem writing and reading this with DataOutputStream/DataInputStream. The signed/unsigned issue won't be a problem if handled carefully.
Can you hear that? That's my theme music. I don't know where it comes from. Check under this tiny ad:
