java.lang.ClassNotFoundException：WebDriver API

我下载了selenium-java-2.0a5.zip

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

并运行以下代码：

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()); } } 

但后来我得到了

  at org.openqa.selenium.example.Example.main(Example.java:13) Caused by: java.lang.ClassNotFoundException: com.gargoylesoftware.htmlunit.WebWindowListener at java.net.URLClassLoader$1.run(Unknown Source) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at sun.misc.Launcher$AppClassLoader.loadClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) ... 1 more 

我错过了一步吗？ 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lib jar。 我确信它们必须在您下载的zip中提供

Answer 2

您似乎在项目中使用“HtmlUnit” ，并且在类路径中缺少其jar。 添加selenium时将其添加到项目属性中。

Answer 3

您想从http://code.google.com/p/selenium/downloads/list下载selenium-server-standalone-2.0a5.jar ，因为这包含依赖项。
