Hi ssharma,

I believe the problem is that you do not get a full product object returned from the getAllProducts calls (this is for performance reasons).

From the javadoc:
"Only Products with a non zero status and non zero invisible are returned. The description (which can be very long) and the array of options are not set. "

To get a fully-populated product you need to call getProduct for each product as you go through your loop.
