JAX-RS JUG Demo CDI and @Singleton Usage

This is the last demonstration I gave at the Greenville Java Users Group (GreenJUG) on CDI and JAX-RS. I cleaned up the code, but not as much as you would think. I managed to code this in about 15 minutes during the meeting live while everyone watched. It was a fun experience, but the best part is that it worked during a live un-rehearsed demo.

It goes to show you that CDI and JAX-RS are simple enough in combination to use in a live high stress demo environment. Imagine what it could do for you in your code. This code was written using NetBeans 7 IDE which may be responsible for the simplicity as much as the other technologies.

Here is the source code: cdi-example.zip

The code below demonstrates some interesting bits. The source code above contains the less interesting POJOs.
