A simple webapp I created for a tech test.
I am not happy with the architecture/design of this application, and probably would find something quite different for an actual production deployment.
The framework I previously used is proprietary, so I just found something online to start from.
When I have access to your applications I'll be able to reuse an architecture your team is familiar with.
It's set for Java 1.8 or better but you might be able to run with 1.6 or 1.7
You must have Maven installed and added to path so you can run mvn.
Also JAVA_HOME environment variable should reference the JDK not the JRE.

cd JavaContactSample
