If you were to create the launcher as a "File" type instead of an
"Application" type, it would work with out having to prefix "java -jar"
to the path. This method will use the same mechanism that Nautilus uses
to handle the jar file - a lookup in the mime-database and then, I'd
guess, and exec to the appropriate app (java) that handles the file's
mime type.

Also note that trying to execute the jar file in a shell (just the file,
no "java -jar" in front) won't work unless you register an interpreter
with the kernel to handle it. Man update-binfmts for more info.
