Build Android XMPP instant messenger and server Example

Question

Backgrounds

I want to learn about instant messenger, both android app and server.

In my first thought, I want to use GCM to communicate. But I found the article below. By this article, GCM is not good for sending messages, and It seems that I need to build dedicated messenger server.

Instant Messaging on Android with Google Cloud Messaging

So I googled how to build instant messenger server. As a result, I found that XMPP is popular technology. But I couldn't found examples.

Finally I found source below. This example seems that includes both android and server side source, but I'm not sure this example using XMPP.

https://code.google.com/p/simple-android-instant-messaging-application/

Q1: Is there a good example source of XMPP Server?

Q2: Does anybody have experience about https://code.google.com/p/simple-android-instant-messaging-application/ ? Is this a example is good for beginner?

Any help will be appreciated.
