Looks like there are a lot of WAR files deployed, and if I read the messages correctly many of them have conflicting contexts (several appear to use "/helloworld"). You should use a unique context for every app. If that doesn't help, try this. Remove all of your WAR files from the deploy directory. From a command prompt (not from NetBeans) start the app server - without your WARs it should start cleanly. Then add you WAR files to the deploy directory one at a time, waiting each time for the WAR to deploy before adding the next WAR. Then post the log output from the "start in xxx seconds" message on.
