Anybody using Resin?

[Steve Brailsford]

I urgently need help in setting up an application.
Assume my application is named testapp.
I have created the entry in resin.conf, <web-app id='testapp'>
I have made the required entries in web.xml,
the structure being:
doc/testapp
doc/testapp/WEB-INF
doc/testapp/WEB-INF/web.xml
doc/testapp/WEB-INF/classes
doc/testapp/WEB-INF/classes/*.class
How do I reference a servlet or tag library from the URL?
Thanks in advance.
