GWT exception : Deferred binding result type should not be abstract Or Rebind result must be a class
In GWT, when you get this error in hosted mode
Deferred binding result type should not be abstract
or
The following error while compiling
Rebind result must be a class
most likely you have forgot to extend your business interface from RemoteService. Therefore GWT engine is trying to instantiate the interface itself. That is , instead of
@RemoteServiceRelativePath("relativeServicePath")
public interface BusinessInterface extends RemoteService
you have written
@RemoteServiceRelativePath("relativeServicePath")
public interface BusinessInterface
