wierless SD shield with wifi Xbee

Hello,
I try to use a wireless SD shield with wifi xbee .
As test sketch I use scan network nomally written for arduino wifi shield.
The soft seems not to discover the Wireless sd shield.
" wifi shield not present"
Is the wifi Library exclusively written for" wifi shield" and the Wireless SD shield is excluded?
The wifi shield has a hanshake line on pin 7, the Wireless sd shield no.
Is there a Library or a sketch specially dedicated for Wireless sd shield?
Thanks for your comments.

Why? You don't have that hardware. Why would you use the software for hardware you don't have?

What a surprise.

Of course it is.

Why do you need software to operate with the shield? The shield can't do anything, unless you want to talk to the SD card. You need a library that works with whatever device you attach to the Wireless SD shield.

I had the Wireless SD shield in stock , so it was normal to try to use it.
You find SD reader on different shields working with the same soft ,
Why not the radios?
Anyway, I ordered a Arduino WiFi shield and hope in fine to find the solution.
Thanks for info.
