New With SAPUI5, help please!

Hi everyone!

After doing some exercises and try to perform the "Split App" from "UI development toolkit for HTML5", I want to do my first app with SAPUI5 and Eclipse (something like the image shown below ).

This is my basic code and structure:

I want to make a full screen with several tabs in the view (something like this)

but I don´t understand why it doesn´t work! Just want to load the Page.view.xml in the shell.

Any help?

So Sorry for my english and for being such a newbie!

And thanks for your time!
