I want to create a map field into my blackberry app using java eclipse, I create a map field and RichMapField and both shows blank page.
Note that my device does not contains a sim card, please can anyone helps me

As far as I can tell, BB maps requires BIS to be enabled. And since you don't have a sim in your device, I'd rate thats the problem.
Do I need to have a BIS or BES service in order to use MapField in the code?
I find this to be really silly and kind of unacceptable, so depending on your requirements, I'd consider Google Maps instead.
Use Google Map in Blackberry application
Bing Maps SDK For Blackberry 6.0 (Accepted answer is an example of using Google Maps installed on the device)
