Java classes are declared in Java, not in C++. 
The correct way to do this is to generate a C++ header using gcjh,
which does the right thing:
// DO NOT EDIT THIS FILE - it is machine generated -*- c++ -*-
#ifndef __Foo__
#define __Foo__
#pragma interface
#include <java/lang/Object.h>
#include <gcj/array.h>
extern "Java"
{
 class Foo;
}
class Foo : public ::java::lang::Object
{
public:
 Foo ();
 static void main (JArray< ::java::lang::String *> *);
 static ::java::lang::Class class$;
};
#endif /* __Foo__ */
 > Cause java::lang::Object is too declared outside of extern "Java".
