Recognizing an app launched from a .jar file

I use a .jar file to launch game client that I wasn't able to install through their normal launcher. Since it isn't an installed application, it doesn't appear under the "running applications" when I try to add app-specific shortcuts. Are there any workarounds or ways to manually add it to BTT?

It currently shows "Launcher" under the running apps, but nothing happens when I add shortcuts to it.
