From what I understand, SWIG is to wrap C++/C to make it appear in Java, and javah is to implement certain java functions in C++ ( aka native functions ).
Is there a tool which can create a C++ wrapper over a java class, so that the caller. of this c++ wrapper doesn't have to worry about java, for example
Input Java is

  class hw {  
    public  void hi() {  
      System.out.println("Hello World");  
    }  
  }  

Tools outputs hw.hh ( and some. c++ files ), which can be used as:

hw *h = new hw(/*JEnv */ env);
h->hi();

Is there a tool available which can do this ?
