without altera.components after create a project

Hi everyone,

I am developing the example of the paper "NIOS II Hardware development", My board is a DE2 - Cyclone2 and i am using Quartus 11.1 + NIOS II Eclipse.

Everything is fine with the sopc, but when i create the project in eclipse, i can see two elements at the left side:

-Source Code

-Syslib

but i can not see the altera.components which links the the source code to alttera components.

Please, somebody help me, i will really aprecciate it.
