There tools to package existing C++ objects as Java Beans and vice versa (the code is compiled as a dynamic link library (dll))

like

(1) VisualAge for Java C++ Access Builder

http://www7.software.ibm.com/vad.nsf/data/document2453?OpenDocument&p=1&BCT

(2) cxxwrap
http://www.execpc.com/~deaven/Dave/Software/cxxwrap/

You may use them.

can you use a JavaBean in a C++ application?

cxxwrap is supported on Unix platform also. VisualAge ?...I have no idea. I never used it but my friends don't talk in favor of it.

Vice versa should not be a problem.

One last question and then I will give you the 300 points.
Can you treat these JavaBeans like objects?

Example
class Foo
{
  Foo();

  void Fx() { cout << "fx" << endl; };
  void Fy() { cout << "fy" << endl; };

};

can I use this class as an object in Java?

Example:
Foo foo;
foo.Fx();
foo.Fy();

Can I use a Java class/object in C++?

Thanks for your help and I promise to give you the points.

You can always use interfaces (public methods) but on
unix platform (gcc compiler - I know..others I do not) it is partially supported.

Have a look at
http://gcc.gnu.org/ml/gcc-patches/2001-03/msg01483.html

for detailed information.
