SomeClientServiceAsync someService = GWT.create(SomeClientService.class);

what does above line means and why cannot i use any other alternatives to instantiate it?

Please help me!

Answer 1

GWT.create is used for deferred binding. This allows you to supply different implementations of the same service based on the user's browser. See the following question:

Why use GWT.create() instead of new?

If you do not need to have multiple implementations of your service, just create it via new!

Answer 2

GWT works by creating a service just like RMI does. Here you are creating the service SomeClientService which resides in the client package. It contains all the functions that can be called server-side.
