[Solved] Maemo5 / Harmattan application icon not shown in menu

So, I’ve created a simple ‘hello world’ code for Harmattan.
Successfully created the .deb file, and deployed it via Nokia RDA ( N9 Model ).

However, my installed application is not shown in the application menu ..
( by application menu I mean where you can find Phone, Contacts, etc etc. )
Did I missed something?
I did no extra configuration for the deployment steps,
I just followed what it tells me.

I am using Qt Creator 2.2.0 for Windows.
Thanks in advance!
