Pounder Java GUI Testing Utility

I'm just starting to program in java. So the question that i'm asking might sound a little silly.

I downloaded Pounder. When I doubleclick on it, it starts. And now I have no idea how to start an application that I have written

My application is located in C:\Dokumente und Einstellungen\alossenko\Desktop\eclipse\workspace\CatalogEditor
It's named CatalogEditor.class

And Pounder is saved to my desktop. I started javax.swing.JTree, it works, i can record and play what i am doind. But how do i start my Application?

Please help.
