For the OP's original problem, for obvious security reasons TC makes it very
hard to access the internal TC objects behind the various Facades from a
webapps code (e.g. a Filter). It should be pretty much impossible if you
are running in a sandbox with the default TC security settings. Overall, if
you really need access to the internal TC objects, IMHO you are better off
using a Valve, since the potential need to modify it when you upgrade TC
versions doesn't go away. If you can do what you need to do with the
operations and properties exposed via JMX on the Manager, then that is
probably cleanest. Otherwise, you would probably need to use introspection.
