I don't know if you've ever deployed a LabVIEW executable before, but you need to remember that they have to have the LabVIEW run-time engine installed on the PC for it to work. You'll also not be able to compile java code inside of LabVIEW directly, so you'll need to compile the Java code into a DLL, then include the DLL with the LabVIEW EXE and call that from LabVIEW.
You'll have to decide if that meets your definition of a "clean, standalone" executable.
As for getting the Java code compiled into a DLL, that's not something I can help you with and I doubt most other members of those board can either. I suggest you search elsewhere for assistance with that if you go that route.
