Hello.

I have one problem I've been dealing with for this week. You see, I'm new to Java, so that's probably it...

Anyways, I've started a project out of pure curiosity. I had it done in Java, but in plain CMD-style, which is not very pretty. It calls one of my ten programs, chosen by the user using "Case". Eg.: If you type 1, it will go to program 1. After you finish it, it goes back to selection until the user press 0.

After that, I've been trying to make a GUI for it. I've been able to create the selector alone and make it respond to the numbers chosen. If you press 1 and click ok, it will tell you you've chosen program 1.

I, however, have not been able to make it run the program. I've been trying to make the program show up in a jPanel, part of the main GUI. I failed miserably.

The program runs in separate but I can't make them run together like the CMD one.

The apps were made in Eclipse SDK 3.5.2 The GUIs were made in Netbeans IDE 6.8

Here's the code for the GUI only (the prints are in PT-BR, my native language):
