Issue: If your deployed EAR file somehow becomes corrupt WildFly will fail to start, and you will be unable to redeploy.
Resolution: Run the script to start WildFly with the --admin-only command so that it will start without trying to start the applications. This will bring up the admin console, and allow you to redeploy in order to resolve the issue with the EAR file.
Note: the command would look something like this:
start-wildfly.bat -c IA --admin-only
