Hello,

I have followed the instructions on the page mentioned above, and can see the Tomcat index page. The servlet example run properly, but JSPs do not. At <http://127.0.0.1:8080/examples/jsp/num/numguess.jsp> I get the following:

Error: 500

Location: /examples/jsp/num/numguess.jsp

Internal Servlet Error:

I'd greatly appreciate your help getting Tomcat up and running. I'm using MRJ 2.2.3 on MacOS 8.5.1.

Yours very truly,
