You can't export a C++ class from a DLL and use it from a different compiler. What you can, and should, do is to export a COM object.

You can't. You could use JNI, but that's pretty horrible, and you'll have to write the code to convert from a C++ object to a corresponding Java object.

You could also look at JNA, which tries to make this a little easier.
