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?
