Trying to launch firefox browser using selenium jar files in eclipse getting e

Question

I'm trying to launch firefox browser from eclipse using selenium as I'm learning selenium.

My tutor wrote the below code but when i'M trying the same code I get this exception-

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

Link1. The latest version can be downloaded from

Code:

package appselenium1;

import org.openqa.selenium.firefox.FirefoxDriver;

public class A {


public static void main(String[] args) {


    FirefoxDriver driver = new FirefoxDriver();
    driver.get("http://www.gmail.com");

    }

    }

You are facing this exception, because you have not used gecko driver , which is required for launching and sending command in selenium.

You can download the latest version of gecko version from here

Try this :

package appselenium1;

import org.openqa.selenium.firefox.FirefoxDriver;

public class A {

static WebDriver driver ; 

public static void main(String[] args) {
System.setProperty("webdriver.gecko.driver", "C:\\Downloads\\geckodriver-v0.20.1-win64\\geckodriver.exe");
driver = new FirefoxDriver();
driver.get("http://www.gmail.com");
}
}

`NoClassDefFoundError` indicates that the classloader which is responsible for dynamically loading classes, cannot find the .class file for the class that you're trying to use. – cruisepandey Jul 19 '18 at 13:13
This exception has nothing to do with selenium. There is something while compiling your java class , I have found one link , go through that that may resolve your problem https://stackoverflow.com/questions/17973970/how-to-solve-java-lang-noclassdeffounderror – cruisepandey Jul 19 '18 at 13:14
How do i launch browser without using gecko.Do i have to use older version of selenium.The link which you sent me above was not of much help i'm just a student, can you help me with it. @ cruisepandey – Ranjith93 Jul 19 '18 at 14:40
Yes you will have to downgrade selenium version along with browser degradation , I believe that will do. Don't worry slowly you would learn. – cruisepandey Jul 19 '18 at 14:42

While you work with Selenium ver3.x, GeckoDriver ver0.21.0 and Firefox ver61.0.1, you need to download the latest GeckoDriver from mozilla/geckodriver and store it anywhere within your system. In your code you need to provide the absolute path of the GeckoDriver through the System.setProperty() line as follows:

package demo;

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

public class A_Firefox 
{
    public static void main(String[] args) 
    {
        System.setProperty("webdriver.gecko.driver", "C:/path/to/geckodriver.exe");
        WebDriver driver =  new FirefoxDriver();
        driver.get("http://www.gmail.com");
        System.out.println("Page Title is : "+driver.getTitle());
        driver.quit();
    }
}

Note: Replace the packagename (demo in this example) with your own package name.
