Please refer to some code where I need not type the password in clear text in the java code. The password that has been used in this sample code is “password123”. SOme methods for encrypting and use that to string instead. I am also googling on this.

“Exception in thread “main” java.lang.Error: Unresolved compilation problems:

I have added the referenced libraries also, and followed all the steps as and when mentioned in this tutorial.

Kindly help in resolving this error.
Also I would like to add, a great job by all the people involved for making this a success.
Thanks a lot.

After some research, i found this link
http://stackoverflow.com/questions/5134953/noclassdeffounderror-in-java-com-google-common-base-function

Then i try to add the selenium-server-standalone-version.jar as another external jar, and it works! (although i still got some errors)

Thank you for your kind words.

public static void main(String[] args) {

System.setProperty(“webdriver.gecko.driver”, “C:\\junit\\webdriver\\geckodriver.exe”);

// objects and variables instantiation
WebDriver driver = new FirefoxDriver();
…
}

I hope that help you.

Best regards,

Bruno

Please help! I really enjoy your blog and I’ve just started learning selenium Webdriver but having problems running simple scripts like this on my laptop “Windows 10”:

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;

public class FireFox {

public static void main(String[] args) {
// TODO Auto-generated method stub

WebDriver driver=new FirefoxDriver();

driver.get(“http//www.google.com”);

}

}
Anytime i run this script, i get this error message in console:

Exception in thread “main” java.lang.IllegalStateException: The path to the driver executable must be set by the webdriver.gecko.driver system property; for more information, see https://github.com/mozilla/geckodriver.
