Change driver=new RemoteWebDriver(new URL("http://192.168.2.2:5557"),caps);
​to ​driver=new RemoteWebDriver(new URL("http://192.168.2.2:5557/wd/hub"),caps);

​and try again.​


Thanks & Regards

Hi,

Its by mistake i forgot to add "/wd/hub".

But when i am trying to access the ChromeDriver through Chrome, i am getting below exception:
Exception in thread "main" org.openqa.selenium.WebDriverException: The path to the driver executable must be set by the webdriver.chrome.driver system property; for more information, see https://github.com/SeleniumHQ/selenium/wiki/ChromeDriver.

But when i used the same path of chromedriver below which is normal ChromeDriver invocation, which works perfect.
System.setProperty("webdriver.chrome.driver", "D:\\UD\\jars\\chromedriver.exe");
WebDriver driver=new ChromeDriver();
driver.get("http://www.google.com");
System.out.println(driver.getTitle());
driver.quit();
Whey i am getting above exception when i ChromeDriver in Grid context??
System.setProperty("webdriver.chrome.driver", "D:\\UD\\jars\\chromedriver.exe");
DesiredCapabilities caps=new DesiredCapabilities().chrome();
caps.setPlatform(Platform.VISTA);
caps.setBrowserName("chrome");
driver=new RemoteWebDriver(new URL("http://192.168.2.6:5555/wd/hub"),caps);
driver.get("http://www.google.com");
driver.findElementByName("q").sendKeys("Hello world");
driver.quit();

Start your node by adding -Dwebdriver.chrome.driver and pass the location of the chrome driver binary to the above mentioned JVM arg and retry your test. 

You cannot use System.setProperty to set a property for the node. The node has to be either spun off by passing that property via JVM args or you can ensure that chromedriver binary is available as part of the PATH variable.

Thanks Krishnan,

Your inputs helped me. After providing the "-Dwebdriver.chrome.driver=chromedriver physical file path",
it started working.

Thanks,
Uday
