The "Removing duplicate" messages are normal and not an
indication of an error. Internally, the "JspServlet"
and "*.jsp" mapping are added by default, which is why you
don't have to have it in your web.xml. Your web.xml update
is causing those defaults to be replaced.
I believe you could put the interceptor class under
TOMCAT_HOME/classes and it will automatically be included
on the classpath. I forgot to mention that you will
need to add this interceptor to your server.xml. You
can add:
<ContextInterceptor
className="your fully qualified classname" />
after the one for WebXmlReader.
