JESS: Newbie Problem running Jess

[Michael Knapik]

I downloaded and unpacked Jess to C:\Jess.   I have the recent java SDK from Sun installed in c:\j2sdk1.4.2_04   I am running XP Pro.   I added the path info in your book (;.;C:\Jess61\jess.jar) to both the Path system variable, the Path User Variable and a new CLASSPATH user variable.   I opened the CommandPrompt and cd'd to C: and tried to execute java jess.Main and got:   Exception in thread "main" java.lang.NoClassDefFoundError: jess/Main   instead of the welcome banner etc.   Thoughts?   Mike
