I'm currently in a very challenging DevOps environment, where Tomcat or
Jetty is not enough:-D

In fact we need to serve both the OFM and EAP stack, sometimes in the same
project. While we use scripting languages mostly, some patterns and lessons
learned could most certainly help in a Java EE or PaaS world, too. Some
parts like Maven are also Java based in our stack.
