Re: For midtier/tomcat gurus. Tomcat configuration question
Rabi, If I'm understanding things correctly, you've basically got a mismatch between how Remedy updated your httpd.conf and your manually maintained workers.properties file. You should be able to comment out the following line if it's still there in httpd.conf: JkWorkersFile /var/tomcat/.../remedy/conf/arsysworker.properties The reason being, you've got essentially the same things defined in your workers.properties file. I'm not sure about the other jk* lines specific to the Remedy settings - if they've already been defined earlier in httpd.conf, you can probably leave them as they are above and comment them out in the Remedy section. You may also need to keep this line if you can: JkOptions +ForwardURIEscaped +ForwardURICompatUnparsed The one line you probably need to keep would be one like JkMount /arsys/* arsysWorker1 If you have that line (or just with arsysWorker), change arsysWorker(1) to remedy, as defined in your workers.properties file: JkMount /arsys/* remedy So, you might end up with just this in your Remedy specific section in httpd.conf: JkOptions +ForwardURIEscaped +ForwardURICompatUnparsed JkMount /arsys/* remedy With the options for the remedy work defined in the file referenced here: JkWorkersFile /someotherlocation/workers.properties Basically, as I understand it (and my understanding is very limited), in httpd.conf, you're simply telling the web server how to hand requests off to the application server (Tomcat), defining workers that know where to forward requests to. Tomcat has the application installed and knows where the files are, because it is managing the application. Apache gets a request for /arsys/something/or/other, and forwards that request onto Tomcat via the port defined in workers.properties. Tomcat processes the request and send the response back to the user through Apache. Try making those changes and restarting Apache (not Tomcat) and see what you get.

Re: For midtier/tomcat gurus. Tomcat configuration question
I believe all Apache defines is the port(s) that are used to send to Tomcat. I think the Tomcat conf/server.xml file defines where the app is located.
