The straightforward way -- write new JNI code, callable from Java, which itself
calls the existing C code.

The expensive way -- use one of:

The interesting way -- read:
http://java.sun.com/docs/books/jni/index.html
In particular chapter 9, the code for which can also be found from the above
page.
