Well, the manifest just lists a class that contains the main() method. 
You could go the Java Universe route and just check the manifest first 
to see what class to run. Alternatively, you can go Vanilla Universe 
with an executable of /usr/bin/java, arguments of -jar test.jar, input 
files to transfer of test.jar, and probably transfer_executable = false 
(because you have java installed everywhere, right? 8o).

IIRC, the Java Universe has some benefits around giving access to some 
remote io and propagation of exceptions that get thrown out of main(), 
but chances are you'll be fine just using the Vanilla Universe.

Best,
