How do I create dynamic legend in REST?

Question

I am going through Generate renderer sample in ArcGIS Java Script API and I want to make similar example using my rest service.

I am going through the sample REST service and wondering that how they created dynamic legend in REST?

I searched and tried to generate the dynamic legend at my end but its not displaying in REST. I am classifying data in Arc Map (using layer properties--symbology) and publishing on server but not getting dynamic legend..

So any help will be great !! thanks in advance : )

Software's : ArcGIS Server & Desktop 10.1 and JSAPI 3.2/3.3

You'll need to use the Legend dijit. You can find documentation here:

You can see a working example here:
