Minimum JDK version supported is 1.8. If you are stuck in 1.7, make sure you get the correct version installed before we proceed.
We will be using Maven 3 as our dependencies management tool, you could use any other or none if you know what you are doing.
We will be using a full blown Java EE container (CDI enabled). You can also proceed with a simple Web Container, as long as you manually add a CDI implementation and bootstrap it correctly.
Glassfish 4 would be a good choice. As long as you get a CDI 1.2 enabled container.
