Have you bothered to read through Sun's online Java/JNI tutorial yet? Looks like they took the tutorial offline, but scroll down the page and find the download link for the old JNI tutorial. Read through that first. You'll have to create a little bit of "bridge" code in C that talks to the JVM environment and handles translations of java types to C types (and back).
