Valve to dump response messages?
After googling, I've found the request dumper valve, but I was wondering if
there was an equivalent for response content? I have been able to rig up a
http servlet filter that can capture and log response messages but i was
looking for a more universal way to accomplish this for all http
requests/responses to tomcat.

A Valve is essentially a Filter except that it will run *before* all
application-defined Filters and it has access to the request/response
objects at a lower level than a Filter would.
Most of those lower-level interfaces also implement the e.g.
HttpServletRequest/HttpServletResponse interfaces, so much of the code
can be copied verbatim from my example.
Or you can use my code as a starting point to write a Valve that uses
those lower-level interfaces. There are no built-in wrappers for
Tomcat's Request and Response objects, though, so "wrapping" them just
requires more work. (I did propose wrapper classes for those, but was
discouraged from adding them to Tomcat proper. You can look in BZ for
some very old code that does that.)
What are you actually trying to accomplish, here? Perhaps neither a
Valve nor a Filter is the best solution.

Thanks Chris, I do have a similar solution using servlet filters, however i
was looking for a solution using a valve. I do not know much about how
valves work yet but i'm digging through the source now...
