Yes, I looked through the code but I'm not that familiar with how
servlet containers work beyond the Servlet API.

I'm not sure I know what you mean by 'web.xml', I don't think I
completely understand how Paperclips works, but it looks like it can
only load servlets from a WAR file. The servlet I'm using was
originally designed with Tomcat in mind. In tomcat, I changed the
global web.xml file (which was executed on per-web-app basis) to map
*.ssjs to the servlet (much like tomcat's own CGI Servlet is mapped to
*.cgi). This was a good solution for that case, but I am now hoping to
be able to hack an existing servlet container so that it uses this
servlet and no other servlets. The servlet itself allows a developer to
write servlets (using the Servlet API) in JavaScript. 

My reasoning is that JavaScript does not require external classloading.
It is somewhat slow to load external class files from a program
compiled with GCJ (yet this is the core of a servlet container). I
would like to disable classloading  in Paperclips and then compile with
GCJ already set to use my servlet and map it to ssjs (code it in, not
configure it with a server.xml file).

P.S. I thought it might be worth mentioning that I ran into problems
when I tried to run paperclips on Sun's JVM, but that was an old
version of paperclips, I might try it again. As I remember it had
something to do with how URLs are handled. If I run into the problem
again I'll let you know (though I don't even have the Sun JVM installed
right now, so I probably won't).
