Apache VirtualHost does not forward requests to JBoss using mod_cluster

Issue

• I see my JBoss nodes and applications enabled on the mod_cluster-manager page, yet my application requests are still returning 404s from Apache and not proxying through to JBoss.
• Applications not available on correct port, but are on mod_cluster_manager port.What could be cause of this.
• If I access http://./abcd I can reach the login page of the application, but if I try to access my other . setup under a different Virtual Host in the same Apache Web Server the message that I receive is "The requested URL /abcd/ was not found on this server".
• How can I have this application available in all VirtualHosts in this WebServer?
• We added a ProxyPass to our VirtualHost for a server outside of JBoss/mod_cluster. Before this was added, mod_cluster proxied requests for JBoss applications as exppected, but now the appications are not proxied. How can we use mod_proxy in our VirtualHost and still have mod_cluster proxy application requests?
