You could also loosen the restriction that the file has to be in a jar.
You can use ftp to copy any file you want to the cRIO, then use "regular" Java ME file io (see
http://www.chiefdelphi.com/forums/sh...d.php?t=85012).
The SDK uses ftp itself to copy your jar file to the cRIO (actually a "suite" file, but similar contents). You can poke around the ant scripts (deploy.xml if I recall) to see how to script ftp copies.
