Help using mod_jk to forward to backend app server

Question

I had mod-jk working a while ago but after switching servers and modifying some files, it no longer works. I am using mod_jk-1.2.28 with JBoss 4.2.3 as the backend.

In the JBoss server.xml file I have the AJP 1.3 connector defined on port 8009 and I am binding jboss to the server's new IP address. The app I am trying to forward to is deployed as:

[TomcatDeployer] deploy, ctxPath=/ManualAlerts, warUrl=.../tmp/deploy/tmp8097651929280250028ManualAlertsApp.ear-contents/ManualAlerts-exp.war/

On the web server, I have worker.properties with a worker set for the JBoss address and port 8009.

The mod-jk.conf has JkMount /ManualAlerts/* worker1.

Shouldn't this forward all requests to the web server with the URL http://address/ManualAlerts/ to the backend app named ManualAlerts?

The mod-jk.log shows:

Running netstat -an on the app server shows jboss listening on 8009 and the local address is the app server's address. In the mod-jk.log it shows connect to (XXX.XXX.XXX.XXX:8009) failed, and the app-server address is correct here, too. I cannot figure out what's causing the issue.

It msay be s good idea to post your mod-jk.conf, workers.properties and the ajp connection definition. Without them, I'd say you should try adding the following mount point:

JkMount /ManualAlerts worker1
