The following link goes into the part on starting up the JVM and invoking a
Java method from a C program which is the top level program. I think this
is close to the scenario which you are describing. This would probably be
the simplest way if you can count on a JVM on the client machine (where the
C program is). If you can't count on a JVM, you're probably not going to
get an ORB either; in which case I'd use sockets to talk from the C program
to another machine somewhere which has a Java program listening on a socket
on one side and calling the EJB on the other.

Take a look a the Java tutorial on JNI, one area specifically
might be:
