Logging stuff for yourself is a nice use case for a Filter.  In fact,
there's an example filter that does this kind of thing in the examples
webapp included with Tomcat 4.  Source code is in file
"/WEB-INF/classes/filters/RequestDumperFilter.java".  You can see how it's
configured by looking at the web.xml file for this app.
