I'm trying to run a JAR file and having problems. The command line interface comes up briefly and says: "Exception in thread "main" in Java.lang.NoClassDefFoundError" and then shows a path to the file I was attempting to run, then several additional lines that I can provide, if needed. The interface that I expect doesn't open. I can run this on my Windows hardware, but not on the virtual machine. It also runs fine in the Mac environment. I tried uninstalling Java, unchecking 3D Acceleration in Parallels, and reinstalling, but that didn't fix it. Any other ideas?
