ATG - Caused by: java.lang.IllegalStateException: jboss.web.deployment:war=/dyn is already installed.

Problem

I recently deployed my ATG application EAR onto my JBoss and started by JBoss Server. The server started but it threw the following exception almost at the end of the startup

5:32:00,577 ERROR [AbstractKernelController] Error installing to Real: name=vfsfile:/C:/jboss-

DEPLOYMENTS IN ERROR:

  Deployment "vfsfile:/C:/jboss-eap-5.1/jboss-as/server/Admin/deploy/Live.ear/" is in error due to the following reason(s): java.lang.IllegalStateEx

ception: jboss.web.deployment:war=/dyn is already installed.

Solution

After a quick analysis I found that the above error was thrown when I had two ATG EARs inside my jboss server's deploy folder. Its always advisable to build all necessary modules into a single ATG EAR and deploy it onto to the application server. I removed the old unwanted EAR and the error vanished.The above error was caused because both my ATG EARs were built with DafEar.Admin which adds the dyn content. Having two EARs could also cause other issues, so watchout.
