Thanks for the reply Kevin. If I don't add the new < Host > entries in server.xml, I get the following error. 12:03:37,589 WARN [TomcatDeployer] Failed to map vhost: epic-test.vetco.com 12:03:37,589 INFO [TomcatDeployer] deploy, ctxPath=/, warUrl=.../tmp/deploy/tmp 47811epic-exp.war/ 12:03:37,651 WARN [config] Unable to process deployment descriptor for context 'null' 12:03:37,870 WARN [config] Unable to process deployment descriptor for context 'null' 12:03:37,901 WARN [config] Unable to process deployment descriptor for context 'null' 12:03:37,948 WARN [config] Unable to process deployment descriptor for context 'null' 12:03:37,979 WARN [config] Unable to process deployment descriptor for context 'null' 12:03:38,026 WARN [config] Unable to process deployment descriptor for context 'null' 12:03:38,057 WARN [config] Unable to process deployment descriptor for context 'null' 12:03:38,089 WARN [config] Unable to process deployment descriptor for context 'null' 12:03:38,120 WARN [config] Unable to process deployment descriptor for context 'null' 12:03:38,198 INFO [TomcatDeployer] deploy, ctxPath=/jmx-console, warUrl=.../dep loy/jmx-console.war/ 12:03:38,370 INFO [Http11Protocol] Starting Coyote HTTP/1.1 on http-127.0.0.1-8 0 12:03:38,386 INFO [AjpProtocol] Starting Coyote AJP/1.3 on ajp-127.0.0.1-8009 12:03:38,401 INFO [Server] JBoss (MX MicroKernel) [4.2.0.GA (build: SVNTag=JBos s_4_2_0_GA date=200705111440)] Started in 19s:703ms If I add the virtual-host to my hosts file and point it to 127.0.0.1, the app works when accessing it locally but from outside the server I still get a DNS error. The host that I am trying to setup is registered with DNS and works if using jboss-4.0.5.GA. When pinging the new virtual host, it resolves to the correct IP address. ..... it just doesn't resolve with 4.2.0.GA.
