Tomcat Woes

I'm having problems now getting my one JBoss/Tomcat server to serve pages for the virtual domains.

...

The server's name is really vulcan.twistedpair.net. Yeah, sci-fi planets for server names. Needed a theme. This site is actually in the ~jkwarren user directory, as hosted by the server. Don't believe me? Try http://vulcan.twistedpair.net/~jkwarren/blogs, and you'll be in the same place as http://jkwarren.info/blogs. So one web server, lots of space, works.

Until I try to make Java work in one of these virtual hosts. There's a simple, stupid page that should display the current date and time on the server. At http://vulcan.twistedpair.net/~jkwarren/date.jsp it works, but even though it's the same directory and the Tomcat is configured (what I thought was correctly), and is obviously handling the request (Tomcat generates the error message), http://jkwarren.info/date.jsp does not work.

I'm on it. Just thought I'd gripe.
