Newb Java Studio Question - Simple

Warning: Very new with Java, but I’m pretty handy with C#.

I’ve built a very simple form-based app in Java Studio Enterprise 8 (my first). It runs just fine inside Studio, but when I double-click on the compiled JAR file outside of Studio, it doesn’t seem to do anything.

Is there an additional step I need to take to compile it so that it will run outside Studio?
