Well, I am sure that you can attach some VB code to an on-click, and
then have that VB code "execute" a java program, however, THINK OF THE
OVERHEAD of something like that....  There are COM/Java bridges
available from sun...

Have a look at this:

Have a look at that product, and see if it can work for you...
