How to type in textbox using Selenium WebDriver (Selenium 2) with Java?

Question

I am using Selenium 2. But after running following code, i could not able to type in textbox.

    package Actor;
import org.openqa.*;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.junit.*;
import com.thoughtworks.selenium.*;
//import org.junit.Before;
public class Actor {
  public Selenium selenium;
  public WebDriver driver;

  @Before
  public void setup() throws Exception{
  driver = new FirefoxDriver();
      driver.get("http://www.fb.com");
  }
  @Test
  public void Test() throws Exception{
      //selenium.type("id=gs_htif0", "test");
      System.out.println("hi");
      // driver.findElement(By.cssSelector("#gb_1 > span.gbts")).click();
          selenium.waitForPageToLoad("300000000");

          WebElement email=driver.findElement(By.id("email"));

          email.sendKeys("[email protected]");
          driver.findElement(By.id("u_0_b")).click();
  }
  @After
  public void Close() throws Exception{
      System.out.println("how are you?");
  }

}

This is simple if you only use Selenium WebDriver, and forget the usage of Selenium-RC. I'd go like this.

WebDriver driver = new FirefoxDriver();
WebElement email = driver.findElement(By.id("email"));
email.sendKeys("[email protected]");

The reason for NullPointerException however is that your variable driver has never been started, you start FirefoxDriver in a variable wb thas is never being used.
