Is there any particular reason why you can't run the jboss/tomcat bundle? It comes fully integrated...
Yes, apache and tomcat were already running for different use. Jboss installed later.
Is that not possible to use tomcat with jboss the way I am trying to use?
I'm sure it's possible...I'm just not sure that trying to do the integration yourself is going to be the "path of least resistance". Would it not be possible to simply move your legacy application from your existing Tomcat to the Jboss/Tomcat bundle installation? If it's just a WAR file, you can just deploy it and you'll be up and running again with no or minor modifications. And Apache can be plugged in easily via AJP12/13 connectors.
