Java EE 7 Rainy Hills problem. It's a Maven Java Web Application Project developed using Nebeans 8.2. I chose WAR packaging because it's simpler and smaller.
It has only one Stateless Session Bean that's used to expose the calculation service. The surface, as a part of the domain problem, was implemented in a Java POJO class.
Since it's a classic problem, I don't implemented it by myself. I looked for some good approaches on the Internet and made some little adjustments.
I also exposed a JAX-RS service, also based in a Stateless Session Bean ir order of exposing a main entrypoint for the application.
At the index.html file I hardcode some links to illustrated the service call.
This project was originally developed using Payara 4.1.
It is tested using JUnit framework and Arquillian. Some of tests I decided to mock by myself in order to keep it simple.
I usually use the Lombok project in all of my sources. I love that project, but in this case, it was used only to generate the equals and hashCode methods.
