RE: Tomcat 3.3a and mod_jk on AIX 4.3.3 built OK, but not sending
requests
The ajp12.id file is used only for shutdown. It isn't used
at all by mod_jk. However, a "bug/feature" in tomcat.sh
would delete this file if Tomcat was started two time in
a row, making it necessary to specify the Ajp12 port in the
shutdown command. I'm not sure if this is what is occurring,
or the absence of ajp12.id is an indication that Tomcat did
not start successfully.
Does the Tomcat log show that the Interceptors are starting
successfully on ports 8080,8007, and 8009?
Also, what is the "test" request you are trying to execute
in your browser? What is the response you get? With
JkLogLevel set to debug, you should see evidence in mod_jk's
log of its inspection of every request that Apache receives.
I'm not sure why you would see any indication of the requests
Apache is receiving.
Cheers,
Larry
