Geronimo - Tomcat and Valve Development
Hi All
I am trying to write a simple Interceptor, reads Headers from requests and
setups info in the Users Session, and I believe a Valve is the way to go and
since my final app server is going to be Geronimo with TomCat I would like
to know Where exactly is the best place to discuss Tomcat Valve development
for Geronimo?

This list is fine. A normal tomcat valve should work fine in
geronimo. IIUC to get your application to use one or more valves you
set up a valve chain using gbean instances (there is an example in
the configs/tomcat/src/plan/plan.xml) and refer to it with a valve-
chain element in a tomcat specific plan (using the http://
geronimo.apache.org/xml/ns/j2ee/web/tomcat-1.0 namespace, the
geronimo-tomcat-1.0.xsd schema) or a tomcat config inside a generic
plan (the tomcat config is in the http://geronimo.apache.org/xml/ns/
web/tomcat/config-1.0 namespace, the geronimo-tomcat-config-1.0.xsd
schema).
If this doesn't help enough you may need to wait for jeff
genender :-). Asking on IRC may also work.

Hi
The only problem I see with that approach is that you have to deploy it via
an EAR or WAR and it will get executed later in the chain of request rather
than earlier. A valve seems to be the only way to go forward for my idea,
unless I am proven wrong when I try it out.

You may want to try doing that in a servlet filter if you can, since
then it would be applicable to any server and you wouldn't need
Geronimo or Tomcat specific settings (you'd just list the filter in
web.xml). I'm not 100% sure that a filter has access to the headers
and session, but I would certainly assume so.
