Test4Simple, is a port for some of the files also found in Test3 project.

The main difference, is that while Test3 is made with a full JEE6/7 stack in mind (targeted glassfish),
Test4 is targeted a servlet-only container such as tomcat.

This means that all EJB etc is removed from test4 and some of the maven dependencies here are bundled where a provided is 
sufficient in test3.

Since Test4 is a fork/copy of test3 there is a posibility of them differentiating on some of the modules, so 
for full reference consult both projects.
