JNI + existing LIBS [Win32]

Question

- C++
- 2 existing *.lib files plus a bunch of *.h files
- no access to the source code
- very advanced libraries with custom classes/types
Q: How to create a Java wrapper for those 2 libraries?
I know that normally I would include 'jni.h' and add special keywords to the code, but:
1. I have no access to the source
2. I know it's very complex and I would drown trying to figure it out
I greatly applreciate any help,

Answer 1

1) Check if SWIG ( http://www.swig.org ) can help you.
2) If you can't use SWIG, try writing an "impedance matcher".
Outline:
C++ DLL -> require complex parameters for input / output
Encapsulate heavily the methods, such that you can use less complex parameters (like XML strings) to the C++ methods. They could be callable from a plain old C program.
If you can call the methods from a plain old C program, you probably can write the JNI wrapper as well.
