Sample Code :

Code:

   VLayout layout = new VLayout(15);  
        layout.setAutoHeight();  
  
        //overrides here are for illustration purposes only   
        RestDataSource countryDS = new RestDataSource() {  
            @Override  
            protected Object transformRequest(DSRequest dsRequest) {  
                return super.transformRequest(dsRequest);  
            }

            }  
        };  
        DataSourceTextField countryCode = new DataSourceTextField("countryCode", "Code");  
        // These lines are not required for this sample to work, but they demonstrate how you can configure RestDataSource   
        // with OperationBindings in order to control settings such as whether to use the GET, POST or PUT HTTP methods,  
        // and whether to send data as URL parameters vs as posted JSON or XML messages.  
        OperationBinding fetch = new OperationBinding();

        fetch.setDataProtocol(DSProtocol.GETPARAMS);

        countryDS.setFields(countryCode, countryName, capital);  
        countryDS.setFetchDataURL("shared/data/countrydata.xml");  //created an xml file with the results as mentioned in the sample country_fetch_rest.xml

        countryGrid.setSortField(0);  
        countryGrid.setDataPageSize(50);  
        countryGrid.setAutoFetchData(true);  
  
        layout.addMember(countryGrid);  
  
       
  
        TabSet tabSet = new TabSet();
