            BindingContainer bindings = BindingContext.getCurrent().getCurrentBindingsEntry();

            OperationBinding operationBinding = bindings.getOperationBinding("getAppointNoSP");

            operationBinding.execute();

            if (operationBinding.getResult() != null) {

               System.out.println("Result" + operationBinding.getResult());

            }else{

               System.out.println("no result");

            }
