Store C++ classes in JNI context

I have two C++ classes, one for creating a factory and another of the type of object which this factory creates.

Code Snippet:

class A{

};

class Factory
{
    public:
        A *CreateObject(char *p);
};

Factory *CreateFactory(char *);

So, I want the similar classes on Java side, for Factory and concrete class A. But, I am not able to understand that, when I call the CreateFactory function through JNI, where should I store the Factory instance which it returns?

Please help!

You can associate native objects with Java objects by creating a private long field in the Java class and store the pointer to the native object in that field via JNI.
