HELP:

I've setup a File Serving Enabler with a small number of HTML files in it... When I point my browser at the index.html page (http://mobius/Big3/index.html), I get a 500 - Error:

A recursive error was detected.
The server cannot use specified error page. Please check the application error-path.

Original Error:
Error Message: Server caught unhandled exception from servlet [File Serving Enabler]: null
Error Code: 500

If you look at the web path for the file-serving servlet in say the
examples webapp, you'll notice that it doesn't have an explicit HTML
file listed, it's just '/'. Your webpath for this servlet should look
like '/Big3/'. Easiest way to do that is to delete and re-add the
servlet, and take the default webpath.
