using JNI , u can call C/C++ functions  from java objects,
while the other way round is also possible , calling java code from C/C++ , but i dont think u'll need that for now, as the 'communication between java and c" can be achieved with JNI

u have to be more specific about your requirement.

if u have already written most of code in C and u want to use it in java, then JNI is the way to go ,
while if u have bunch of java classes and u want to invoke them from C/C++ then  the "other way"
