What Yoav (Cicer0 on irc as a guess ;-) ) says is true.... if you need
special processing based on the url, implementing a filter is the most
straightforward, simple and elegant way. By no means you should need to
modify the tomcat codebase for a special app, because that way you're
ensuring non-portability, and that totally breaks the spirit of Servlets.

Hi,
Can you just use a Filter and save yourself a ton of trouble?

Subject: Subclassing DefaultServlet
Hi,
I've added some functionality to DefaultServlet by subclassing it (i.e.
we need to do some special processing to certain URLs, for others I
will
just call super.doGet(...)). I compiled the DefaultServlet subclass
against Tomcat's servlets-default.jar in server/lib and deployed it in
my web application (adding a relevant servlet mapping to my web.xml).
When I first tried it I got a ClassNotFoundException for
DefaultServlet,
probably due to the fact that the Tomcat server and the web
applications
use seperate class loaders, so our web application's class loader does
not have a copy of DefaultServlet loaded. I had to copy several JARs
from server/lib to my web application's WEB-INF/lib directory,
including
servlets-default.jar, which contains DefaultServlet. I'd rather just
refer to the JARs in server/lib, though. That way I know that when the
web application is deployed to a newer version of Tomcat, the
DefaultServlet I'm subclassing from and the one Tomcat uses will be the
same.
Besides symlinking, is there any way achieve this? Can I tell tomcat to
also include server/lib in the classpath for my webapp?
Thanks in advance,
Frans
