I agree with Lew, it's darn hard to guess what you actually intend to do

multiwindow-multiclass systems usually communicate through the usual
listeners and by forwarded methods from the custom class to a contained
Swing component.

Lew assumes that you want to load a file and execute it. Run some code.
  I assume that too.

I can see a couple of different ways of doing this. Using listeners is
correct and the usual way of doing it.

If you don't know what code is going to be run, however, you might need
a ClassLoader to find and load the class up. If you have bits of code
that are supplied by two different groups, this is one way to join them
up. One bit of code loads the other with a class loader.

The other possibility is to use Reflection. This is what programs like
Tomcat, Netbeans, and Eclipse use to "peak inside" other bits of code
and understand it's internal structure.

Let us know if any of these ideas are close to the mark.
