The code is - import org.openqa.selenium.*; import org.openqa.selenium.firefox.FirefoxDriver;

public class Screen_1_Monster {

WebDriver driver;
WebElement wb;
public void operation() throws InterruptedException{
   driver = new FirefoxDriver();
  //going to the desired website
  driver.get("https://login.naukri.com/nLogin/Login.php?URL=http%3A%2F%2Fmy.naukri.com%2FMailers%2Fshowdnc%2F%3Furl%3Dhttp%3A%2F%2Fmy.naukri.com%2FHomePage%2Fview%3Fid%3D6e346be1ad03f4d67d75e5911b88ec3df281f50b07bbd08fb4c7f074e87577b79a86cc384cde9c370d99ad6a3af22255");

  //User id 
  wb = driver.findElement(By.id("emailTxt"));
  wb.click();
  wb.sendKeys("an@gmail.com");

  //Password
  wb=driver.findElement(By.id("pwd1"));
  wb.click();
  wb.sendKeys("2738");

  //Login Button
  driver.findElement(By.id("sbtLog")).click();
  Thread.sleep(20000);
  //if Usename/Password is incorrect
  wb=driver.findElement(By.id("srvErr"));
  String error=wb.getText();
  String e=wb.getAttribute("value");
  System.out.println(error +"  "+ e);
  //Get status of Welcome page
  String title=driver.getTitle();
  System.out.println(title);
}//operation

 public static void main(String args[]) throws InterruptedException{
   Screen_1_Monster s = new Screen_1_Monster();
   s.operation();
 }
}//Scrren_1_Monster

Answer 1

Add dependency (pom.xml)

<dependency>
    <groupId>log4j</groupId>
    <artifactId>log4j</artifactId>
    <version>1.2.17</version>
</dependency>

As of log4j version 0.8.5, at class initialization time class, the file log4j.properties will be searched from the search path used to load classes

PropertyConfigurator.configure(System.getProperty("user.dir") + "/src/resources/log4j.properties");

Create log4j.properties file

log4j.rootLogger=DEBUG, file

log4j.appender.file=org.apache.log4j.RollingFileAppender
log4j.appender.file.File=target/logs/httpClient.log
log4j.appender.file.MaxFileSize=10MB
log4j.appender.file.MaxBackupIndex=1
log4j.appender.file.layout=org.apache.log4j.PatternLayout
log4j.appender.file.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n

It's enough.
