Re: [vox-tech] calling java from within C

I'm trying to figure out how to call Java from within C.

It appears that I have three options:

1. If the Java is already running as a process, there's something called
   CORBA which can be used.
2. JNI which appears to be most popular.
3. CNI which someone said was 'vastly' more efficient than JNI.
CORBA is a remote procedure call interface, like RMI or SunRPC. More generally it's a form of interprocess communication, in the same class as pipes, message queues, and TCP connections. If you want to implement this as client/server or peer-to-peer or some other model where the C and the Java are in two separate processes, then CORBA is one way to do it.

If you want to embed a JVM into another program, The JNI specification is at <http://java.sun.com/j2se/1.5.0/docs/guide/jni/index.html>. The document describes functions for creating a JVM as well as for calling native code from Java. I haven't done it myself, but the spec looks pretty straightforward.
