Java Code which i have written-

import java.util.List;
import java.util.concurrent.TimeUnit;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.interactions.Actions;

public class SortingTable {
    public static void main(String[] agrs) throws InterruptedException{
    WebDriver driver = null;
    try{
    System.setProperty("webdriver.chrome.driver","E:\\chromedriver.exe");
    driver= new ChromeDriver();
    driver.manage().window().maximize();
    //Authentication pop-up
    driver.get("https://accounts.google.com/ServiceLogin?service=mail&continue=https://mail.google.com/mail/");
    driver.findElement(By.xpath(".//*[@id='Email']")).sendKeys("Gmail Username");
    driver.findElement(By.xpath(".//*[@id='Passwd']")).sendKeys("Gmail Password");
    driver.findElement(By.xpath(".//*[@id='signIn']")).click();
    driver.manage().timeouts().implicitlyWait(14000, TimeUnit.SECONDS);
    WebElement wb = driver.findElement(By.xpath(".//*[@id=':j']"));
    wb.click();
    driver.findElement(By.xpath(".//*[@id=':1h']")).click();
    driver.manage().timeouts().implicitlyWait(14000, TimeUnit.SECONDS);
    Actions action = new Actions(driver);
    action.moveToElement(driver.findElement(By.xpath(".//*[@id=':16r']/div/div[2]"))).perform();
    driver.manage().timeouts().implicitlyWait(14000, TimeUnit.SECONDS);
    driver.findElement(By.xpath(".//a[@title='Other Contacts (16)']")).click();
    driver.manage().timeouts().implicitlyWait(14000, TimeUnit.SECONDS);
    //This is the page which is having the contact 
   List<WebElement> list = driver.findElements(By.xpath(".//*[@id=':17h']/tbody/tr/td[4]/div"));
    for(WebElement lst : list){
       //Trying to read the contact
        System.out.println(lst.getText());
    }//for
    }catch(Exception e){
        e.printStackTrace();
    }//catch
    finally{
        Thread.sleep(4000);
        driver.quit();
        System.exit(0);
    }//finally
  }//main
}//SortingTable

I am trying to read data inside the contacts page but getting this Exception.

  • Can u please point out line no. 36? What is that line doing? Another thing, why r u giving implicitlyWait multiple times. Specifying it once in the driver instance is more than enough. If u r waiting for specific things use explicit wait. And 14000 seconds? That's 3.8 hrs... Commented Jan 21, 2015 at 12:10
  • @VivekSingh The exception is thrown on System.out.print(lst.getText()); inside the for loop. Commented Jan 21, 2015 at 12:51
  • If you are trying to fetch the mail address try to use xpath - //tr[@class='MT']/td[5]/div. Coz am able to fetch the details. Commented Jan 21, 2015 at 13:18

Reset to default

This is because of the following two reasons from here:

A stale element reference exception is thrown in one of two cases, the first being more common than the second:

The element has been deleted entirely. The element is no longer attached to the DOM.

Generally this happens in ajax based sites. One way is to solve this is to refetch the element, because of ajax call the DOM would have been changed.
