Does the jar's manifest have a Main-Class attribute in it? The message says it doesn't. Perhaps it was not supposed to be an executable jar (not all jars are executable). Or perhaps the person who created it didn't do it correctly.

Just a hunch: check line endings.I could easily be wrong here, but I've been bitten on the *** by this particular issue before.
