1.  Do you have swt.jar and the required swt.whatever.dll in the 
directory in which you're trying to run program.jar?

2.  If you execute java -cp "swt.jar;." -jar program.jar, does that work?

3.  Have you checked to make sure the manifest file in program.jar 
really contains the classpath info?  (You can open program.jar using 
your favorite zip utility, then open manifest.mf in a text editor and 
check it.)
