1+| TomEE Philosophy
|
Apache TomEE, pronounced "Tommy", is an all-Apache Java EE 6 Web Profile
certified stack where Tomcat is top dog. Apache TomEE is assembled from
a vanilla Apache Tomcat zip file. We start with Tomcat, add our jars and zip
up the rest. The result is Tomcat with added EE features - TomEE.

Its core values are:

- Be Tomcat
- Be certified
- Be small
