CLMsn won't run

Hey there,
I’ve found this program http://users.skynet.be/fa397903/myprogs/clmsnv01/index.html and I can’t get it to work using java -jar, it keeps saying it’s unable to access the jar file. It isn’t autocompleting the file name either.

Anyone know how I could run this program using openSUSE 11?

Thanks, Dan.
