Hello,

I'm attaching the library source code. It is in Boost license 1.0.

The library is based on luabind ideas, which is based on Boost.Python.

The JNI interface makes a few things much harder, and makes mismatches
almost always fatal and almost impossible to discover beforehand,
which makes developing for JNI much harder.

I'm implementing the features as I need it, so it is very incomplete.
But it is possible to register a class like this:

javabind::class_ component_class = env.find_class("java/awt/Component");
javabind::register_class
  (
    javabind::reg::class_<awt::component>(component_class)
    .constructor(boost::bind(boost::value_factory<awt::component>(), _1, _2
                             , jvm))
    .def<javabind::int_(awt::component const&)>
    ("nativeGetWidth", boost::bind(&awt::component::width, _1))
    .def("nativeGetHeight", &awt::component::height)
    .def("nativeSetX", &awt::component::set_x)
    .def("nativeSetY", &awt::component::set_y)
    .def("nativeSetWidth", &awt::component::set_width)
    .def("nativeSetHeight", &awt::component::set_height)
    .def("nativeGetX", &awt::component::get_x)
    .def("nativeGetY", &awt::component::get_y)
    .def("nativeSetVisible", &awt::component::set_visible)
    .def("nativeIsVisible", &awt::component::is_visible)
    .def("nativeSetPreferredSize", &awt::component::set_preferred_size)
    .def("nativeSetDelay", &awt::component::set_delay)
    .def("nativeGetPreferredSize", &awt::component::get_preferred_size
         , "java/awt/Dimension")
    .def("nativeSetFocus", &awt::component::set_focus)
  );

And to call a method like this:

javabind::method<void(javabind::object)> initxlet = jtv_xlet_class.method
  <void(javabind::object)>("initXlet", "javax/tv/xlet/XletContext");
initxlet(user_xlet, xlet_context);

Any comments are appreciated,

Regards,
