best way to run my command-line program and see results?

[java]

I'm trying to use FreeCommander the same way I used FAR manager before:
I edit a command-line program (say, my ANT build script) and then need to run it using some hotkey and see the output.
what's the best way to do that?
if I use "Favorite" icon, it can start a program, but
it opens a separate DOS window and closes it automatically when my script is done. so I can't see results.
(In FAR manager you can see results in the same main window).
