Ugly, huh? Here's how to fix it…

We’ve recently been in the transition from using Spring in a Tomcat environment to Java EE7 in Wildfly? (still finalizing the container of choice).

Since we’re in transition, we’d like to run the application in both Tomcat and Wildfly, without having to make changes to the bundled application. It should just work on deploy. Here’s how to do it…
