Tomcat listening or not on 'localhost:8080' is independent of whether your WAR is deployed and unrelated to use of deploy-hasingleton. So, you should start investigating there; find out why Tomcat isn't listening on the expected port. The war not deploying may just be a further symptom of a problem with the webserver. If you are running 2 nodes on the same machine, how are you avoiding port conflicts? Using ServiceBindingManager or using "-b localhost" on one and "-b www.xxx.yyy.zzz" on the other?
