Unable to Understand Message GCM

Question

I'm dealing with Eclipse Luna to build the web app (jsp,java) while dealing with Eclipse Juno to build the android app. Plus, i'm referring to this link as my tutorial http://javapapers.com/android/google-cloud-messaging-gcm-for-android-and-push-notifications/

Registration id generated successfully in android device. This what appears when the message is push respectively in the GCM

[ messageId=0:1407227521756362%31e4cc17f9fd7ecd ]

What does it mean? How to fix it since i should have a message received at the Emulator and im not getting it.....?

Thank you.

As it seems that my comment helped solve the problem, I'm posting it as an answer :

If your device is connected to the internet with WiFi, you have to make sure ports 5228,5229,5230 are not blocked (usually 5228 is enough).
