<pre>I'm new to servlet and java and use Window2000. I installed apache 
web server and tomcat servlet engine. And some test servlet is working
well. So I tested some book's sample servlet(Applied XML Solutions 
chapter 4 : Publish servlet) to only get the following error message.

Error: 500
Location: /examples/servlet/Publish
Internal Servlet Error:
