That certainly seems like the simple way to solve the problem. I was
just wondering if I was overlooking a simple way to do this via web.xml
servlet-mapping. I was trying to avoid having everything hit the same
doGet().

Why not have 1 servlet and based on a parameter / url, serve 2 different
outputs?

if(request.getString("asXML") !=null)
   showXML();
else
   showOtherStuff();

Save yourself the hassle of dealing with jndi / contexts / spring or
SingleTons
