To build, deploy, and run the examples, you need a copy of the Java Platform, Standard Edition Development Kit (JDK). You must use JDK 7 Update 65 or above or JDK 8 Update 20 or above. You can download JDK software from http://www.oracle.com/technetwork/java/javase/downloads/index.html.
I think JDK 8 is required, I think we provided OpenJDK link mainly.
And should add the tutorial-example link(maybe in the preface as a link of all resources).
