To access a REST API you can use RestClient.

     import com.gluonhq.connect.provider.RestClient;

     RestClient restClient = RestClient.create()
         .host("http://myhost.com")
         .path("restservice/login")
         .queryParam("username","myname")
         .queryParam("password","myencodedpassword")
         .method("GET");
     GluonObservableObject<User> sample = DataProvider.retrieveObject(restClient.createObjectDataReader(User.class));

To then handle the result you can use the stateProperty

    sample.stateProperty().addListener((obv,ov,nv)->{
         if(nv.equals(ConnectState.SUCCEEDED)){
             User loggedInUser = sample.get();
         }
    });

you can use initializedProperty as well.

what is user.class here ? – Amit Aug 08 '16 at 12:06
User.class is a POJO. You must provide this to match the object being returned. [Retreive Object](http://docs.gluonhq.com/connect/1.0.0/#_retrieving_an_object) – AhaMoment Aug 08 '16 at 19:15
How i will use `ProgressIndicator` for background progress . – Amit Aug 09 '16 at 12:50
I haven't found anything for the DataProvider that gives a progress value. Use the Indeterminate progress indicator. – AhaMoment Aug 12 '16 at 17:28
