抛出java.lang.ClassNotFoundException：webdriver的API

Question

我下载了selenium-java-2.0a5.zip

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

，跑到下面的代码：

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()); 
    } 
} 

，但后来我

at org.openqa.selenium.example.Example.main(Example.java:13) 
Caused by: java.lang.ClassNotFoundException: com.gargoylesoftware.htmlunit.WebWindowListener 
    at java.net.URLClassLoader$1.run(Unknown Source)

我错过了一个步骤？我确保将selenium-java-2.0a5.jar导入到项目中。

Answer 1

htmlunit jar不在类路径中。包括selenium-java-2.0a5.jar的依赖库lib。我确信他们必须在您下载的zip文件中提供

Answer 2

您似乎在项目中使用了“HtmlUnit”，并且它在类路径中缺少它的jar。 添加硒到你的项目属性，因为你添加硒。

Answer 3

您想从http://code.google.com/p/selenium/downloads/list下载selenium-server-standalone-2.0a5.jar，因为这包括依赖关系。
