I'm not sure if anyone will be able to help me, but I am having difficulties running the JHDL program from www.jhdl.org. I downloaded the OS X version of the installer and it installed fine. I then set up the proper class path from the readme file so the program would run. When i double click the .jar file to run it the license window appears and you then click ok. After that nothing happens. When I try to run the program from the terminal with the command java JHDL.jar, i get the message "Exception in thread "main" java.lang.NoClassDefFoundError: JHDL/jar". I know this program is a little obscure, but if anyone has used it help would be greatly appreciated.
