I don't completely understand the issue(s), but consider this, 

<servlet-mapping> 
   <servlet-name>BooServlet</servlet-name> 
   <url-pattern>/*.boo</url-pattern> 
</servlet-mapping> 

<welcome-file-list> 
   <welcome-file>index.jsp</welcome-file> 
   <welcome-file>index.boo</welcome-file> 
</welcome-file-list> 

Is the problem that by the time the 'welcome file logic' gets a chance
to handle the request, the logic that would have been able to pass this
request off to a servlet is way too far up the call stack?    It is
almost like the DefaultServlet would need to open a connection to the
loopback and check each "welcome file" URI to find one that gets to
something useful (this is just a mental exercise, don't get excited I
wouldn't think of implementing this.)

Cheers,
-bob
