java -classpath c:/whatever/rmmlite.jar;c:/whataever2/jemplode.jar org.jempeg.empeg.manager.Main

I believe with -jar you can't also specify additional classpath (you have to instead define the classpath inside of the MANIFEST.MF file in the jar itself).

You also can't just double click on the jar for this -- you will have to make a batch file with that line in it (for the time being). On linux, you'll want to change the ";" to a ":" in the classpath separator.
