Selenium WebDriver的简单测试设置失败

问题描述：

我只是想执行基本的硒测试。没什么特别的，只是为了确保它的工作。但是引发异常。我能做什么错？ java -jar selenium-server-standalone-2.24.1.jarSelenium WebDriver的简单测试设置失败

import static org.junit.Assert.fail; 

import java.util.concurrent.TimeUnit; 

import org.junit.After; 
import org.junit.Before; 
import org.junit.Test; 
import org.openqa.selenium.By; 
import org.openqa.selenium.NoSuchElementException; 
import org.openqa.selenium.WebDriver; 
import org.openqa.selenium.firefox.FirefoxDriver; 

public class Selenium { 
    private WebDriver driver; 
    private String baseUrl; 
    private StringBuffer verificationErrors = new StringBuffer(); 

    @Before 
    public void setUp() throws Exception { 
     driver = new FirefoxDriver(); 
     baseUrl = "http://www.google.de/"; 
     driver.manage().timeouts().implicitlyWait(20, TimeUnit.SECONDS); 
    } 

    @Test 
    public void testSeleniumWeb() throws Exception { 
    //empty just for testing 
    } 
}

抛出：

当然我开始使用服务器

它看起来像是在寻找一个不支持getTextContent（）方法的旧XML解析器（Apache Crimson）。 – 2012-07-19 09:25:29

答

它无关，与你的代码。你有一个类路径问题。有些类依赖于ElementNode2的不同版本，而不是类路径中第一个找到的版本。

如果你看看jarfinder，你可以看到在JDK 1.4之后，这个类包含在Java运行时（rt.jar）中。

我怀疑你使用的JDK版本比WebDriver针对的版本要旧。 WebDriver需要JDK 1.6+。
