Error during Java program execution

This is a discussion on Error during Java program execution within the mumps forums in Programming Languages category; Hello. I am following along to training at Intersystem's E-Learning site and most recently have been listening to the Cache Java binding lesson. After setting up a Java projection in the designated Cache class, he runs a Java test program. In doing this I get the following error: C:\InterSystems\Cache2007-11-420-0\Dev\java\samples>java CJTest1 Exception in thread "main" java.lang.NoClassDefFoundError: com/ intersys/objects/ CacheDatabase at CJTest1.main(Unknown Source) C:\InterSystems\Cache2007-11-420-0\Dev\java\samples> I assume that the Java system cannot find the source for com.intersys.objects.CacheDatabase . But I'm not sure how to proceed from here. Any thoughts? Thanks, Steve P.S. I've also posted this at the intersystems.public.cache group....
