I use mod_jk (ajp) to connect Apache and Tomcat. I made changes to the Apache httpd.conf file (you probably won't need the same set and there are others):
LoadModule jk_module modules/mod_jk.so
JkLogStampFormat "[%a %b %d %H:%M:%S %Y] "
JkOptions +ForwardKeySize +ForwardURICompat -ForwardDirectories
JkRequestLogFormat "%w %V %T
The workers.properties file contains this:
To direct URLs I use this in the virtual hosts section:
JkMount /timesheets ajp13
JkMount /timesheets/* ajp13
JkMount /timesheetadmin ajp13
JkMount /timesheetadmin/* ajp13
JkMount /testingdb ajp13
JkMount /testingdb/* ajp13
This info is from an old backup (I'm not at work at the moment) and I can't recall why I have the top directory as well as the wildcard, but google may help.
