Hello,

I use JNI calls for some Java classes. Some Java classes are generic 
classes like:

class mytestclass<T> {

    public native void mymethod();

}

The stub shows:

JNIEXPORT void JNICALL Java_mytestclass_mymethod(JNIEnv* p_env, jobject 
p_object)

How can I get from the jobject which object type is the generic 
parameter T? Because I would
like to create different codes if I do something like:

mytestclass<int> x = new mytestclass<int>();
x.mymethod();

mytestclass<String> x = new mytestclass<String>();
x.mymethod();

Thanks

Phil
