To view the discussion, visit: http://community.jboss.org/message/629156#629156 -------------------------------------------------------------- Hello I am new to JBoss and I am working in SpringSource Tool Suite (STS) 2.71. The application is built on the Spring framework. I have not modified any settings with the server since installing it. Perhaps I need to modify some settings? When trying to deploy my application to JBOSS 5.01, I am getting an error that I do not understand. Here is my stack trace: ERROR [AbstractKernelController] Error installing to Configured: name=jboss.web.deployment:war=/MVCProj1 state=Instantiated mode=Manual requiredState=Configured
