Are the Tomcat instance running on the same physical server and you are just using IP Aliases, or are the workers running on 3 sperate backend machines?
You apache config looks OK, so I don't believe its an issue with Apache Virtual Host configuration. I believe all work in being forwarded to Demo1 only. I believe you can have multiple instances of tomcat listening on the same port by specifying an IP address in the connector. But I find it much easier just to congigure each instance to listen on a different port. If you check your other 2 workers log files, you will probably see an error similar to "Bind address already in use". Modify each Tomcat instance to the SHUTDOWN and AJP listener are each on unique ports; For example, In each respective instance server.xml use; Demo1 Shutdown: 8001 Demo1 HTTP: 8081 Demo1 AJP Listener: 8101 Demo2 Shutdown: 8002 Demo2 HTTP: 8082 Demo2 AJP Listeer: 8102 Demo3 Shutdown: 8003 Demo3 HTTP: 8083 Demo3 AJP Listern: 8103 Restart each instance (check the catalina.out for errors) Modify your workers.properties file to relect the new AJP listen ports Restart Apache -----Original Message----- From: Dan Barron [mailto:[EMAIL PROTECTED] Sent: Wednesday, March 30, 2005 3:48 PM To: Tomcat Users List; Tomcat Users List Subject: Re: Apache as front-end for several tomcat If you are running multiple instances of Tomcat, from what I understand and from my configuration (i run two Tomcat/mod_jk2 with Apache) you would then need each of them to listen on a different port. Right now the only instance that will receive requests via the worker is the instance that is using port 8009. At 01:33 PM 3/30/2005, Christophe Lemaire wrote: >Not sure.
