{

@Inject

          @Inject
            TestTempData tmpData; //**Returning null**
        public WebDriver driver;
        
        public CreateWebDriver ()
        {
        
        driver = new RemoteWebDriver("http://hub-address:4444/wd/hub")
    
       System.out.println(tmpData); // **Throwing Null pointer Exception** 
        
        }
        }
