JNI: Call java from C++ lib

[debelizmaj]

I write some code for my native android lib to communicate with smart card via jni.

There are: Library c++ code, JavaNativeCaller.cxx class and java.class.

But, when i start my program and call library there is error in env-FindClass("MyClass") (returns null).

How to edit Makefile and include my java.class into native library? Now java.class doesn't exists. I don't have idea how to solve this problem.

Please help!
