java.lang.ClassNotFoundException: WebDriver API

I downloaded the selenium-java-2.0a5.zip

http://code.google.com/p/selenium/downloads/list

and ran the following code:

package org.openqa.selenium.example;

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.htmlunit.HtmlUnitDriver;

public class Example  {
    public static void main(String[] args) {
        // Create a new instance of the html unit driver
        // Notice that the remainder of the code relies on the interface, 
        // not the implementation.
        WebDriver driver = new HtmlUnitDriver();

        // And now use this to visit Google
        driver.get("http://www.google.com");

        // Find the text input element by its name
        WebElement element = driver.findElement(By.name("q"));

        // Enter something to search for
        element.sendKeys("Cheese!");

        // Now submit the form. WebDriver will find the form for us from the element
        element.submit();

        // Check the title of the page
        System.out.println("Page title is: " + driver.getTitle());
    }
}

but then I got

    at org.openqa.selenium.example.Example.main(Example.java:13)
Caused by: java.lang.ClassNotFoundException: com.gargoylesoftware.htmlunit.WebWindowListener

    at sun.misc.Launcher$AppClassLoader.loadClass(Unknown Source)
    at java.lang.ClassLoader.loadClass(Unknown Source)
    ... 1 more

Did I miss a step ? I made sure to import the selenium-java-2.0a5.jar into the project.

htmlunit jar is not in the classpath. Include dependency lib jars of selenium-java-2.0a5.jar as well. I am sure they must have been provided in the zip you downloaded

You seem to use "HtmlUnit" in your project and its jar is missing from classpath. Add it to your project properties as you added selenium.
