I have bunch of classes written in Java which have methods that return interfaces and 
also have methods which have interfaces as parameters. I have a client written in 
Visual C++ to take advantage of COM interfaces to Excel which is the output. Between 
the Visual C++ code and the Java classes I have incorporated the use of JNI. I'd like 
to replace the JNI paradigm in this system with Web Services. However, I am trying to 
understand the best way to pass back information to the MS client. Is serialization 
/deserialization of the returned interfaces my only option to interoperate between MS 
C++ client and Java code? If so, is there any documentation on how to do this? If not, 
what other possibilities are there?
