GWT error - Deferred binding result type should not be abstract (or) Rebind result must be a class

When you encounter following GWT error message


'Deferred binding result type should not be abstract'

in hosted or development mode


'Rebind result must be a class'

upon GWT compilation

then mostly it means that your GWT client service interface didn't extend the required marker interface

So change your service from 

interface SampleService{



interface SampleService extends RemoteService {

Hope this helps. Thanks to this post that helped me initially.
