check CLASSPATH and make sure that it includes the correct path to javabook. If your java program is in the same directory as javabook, be sure to include ".;" in your CLASSPATH string. HTH Junilu

If your javabook package is jar'd up, you have to include the actual jar name (add the end of the proper path) in your classpath. Maybe that's it?
Also, if you're using an IDE of some sort, be aware that not all of them use system classpath settings. You would need to look for something like a 'library' to add jars to, or something similar. [This message has been edited by Mike Curwen (edited May 29, 2001).]
