Hi folks,
How can a C program call a Java program? Is there any reference on
that point? I need some help on this issue, thanks.

If you're asking how to start a Java program from a C program, then you
should ask comp.lang.c - they might give you trouble since that problem
is really OS dependant. It's just a matter of running the java.exe (or
java) program with the correct arguments.

If you asking how to run C code from inside a Java program, Google for JNI.

JNI can achieve both calls to C from Java and vice-versa as per OP
requirements.

JNI might be a better option here, depending on what you're doing. It's
generally more powerful (and possibly more efficient) than launching
java.exe as a separate process.
