Hi Nik:
            The use of COM, is of course thank to the capacity of Microsoft
Visual J++ to compile a Java program to a COM .DLL file. The use of the Java
Toolbox/400 in that program (Java) is like any other standar Java program.
There are litle thing's that you must care, like that you can't throw an
Exception in a function of the COM object.

            I can send you our own little Java if you want. Of course it
isn't a general purpose solution, but it can help.

            The use of COM is for integrate it in an Microsoft environment,
easy. But there are other options out of that. For example you can use the
Java Toolbox/400 in environments like Servlets, in that case you donīt need
COM, just Java programming.
