JNI - Calling Java Method from C?

The problem is that your static pointer to your jobject is no longer valid. You need to protect it from any garbage collector runs. This can be done by using global references instead of local ones.

Instead of just assigning the pointer create a globalRef.

You must not simply store pointer to an object, as your error says. When you want to store it, you have to store local or global reference to object. See http://docs.oracle.com/javase/6/docs/technotes/guides/jni/spec/functions.html#global_local.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
