I'm running JBoss 5.1.0 with JDK 1.6 and having problems trying to start our cfusion.ear. It was working fine until a developer added an almost empty jboss-web.xml file while trying to get some code to work. I tried removing the xml file but had no luck. When trying to start the EAR file it was giving the "Web mapping already exists for deployment URL" error. I renamed the ROOT.WAR file and tried to start the cfusion.ear but it is now failing with the following details:
I thought there was a forum thread where this was discussed earlier, but i couldn't locate it now. I think the cfusion.ear packages some jars which are already available in the JBoss server. Do you have any JBoss specific jars in the ear?
