The application directory under webapps is named "timesheet", therefore, the context

I THINK I've figure out that MySQL's Connector/J jar worked in jre/lib/ex when I was

Thanks for your comments.
I think the problem may be that I don't have the MySQL Connector/J jar in the

the places the MySQL documentation recommended. I need to try again with it in the
new location.

You need to define a "context" in the conf/server.xml file:
The path attribute represents the path that appears in the URL following
