异常与Firefox网页司机

Question

我的代码开始硒如下：

startServer(); 
Integer port = 4545; 
String browserString= "*firefox"; 
selenium = new DefaultSelenium("localhost",port,browserString, url) { 
public void open(String url) { commandProcessor.doCommand("open", new String[] {url,"true"});}; 
}; 
logger.info("Start Selenium "); 
selenium.start(); // <------ SeleniumException here 
logger.info("Selenium started"); 

，我得到的是堆栈跟踪：

我用硒的Java-2.40.0和Firefox 26 。

但是，下面的代码工作：

WebDriver driver = new FirefoxDriver(); 
driver.get("http://myhostname:myport/myapplicationname"); 
WebElement userId = driver.findElement(By.name("userId")); 
userId.sendKeys("coolusername"); 
WebElement password = driver.findElement(By.name("password")); 
password.sendKeys("ultrasecretpassword"); 
password.submit(); 
System.out.println("Page title is: " + driver.getTitle()); 
driver.quit(); 

所以这不是Selenium版本与Firefox兼容的问题。

硒试图在这个网址找到一些的servlet：

http://localhost:4545/selenium-server/driver/ 

但收到一个404错误。

Ca你帮我吗？

Answer 1

确保Firefox安装在默认位置。可选的，你可以给的绝对路径浏览器：

String browserString = "c:\\program files\\mozilla firefox\\firefox.exe"; 

Check the source and documentation以获取更多信息。

但是，如果您不想提供Selenium RC，我建议使用驱动程序（如在工作示例中）。

Answer 2

望着source code of the DefaultSelenium class，你可以注意到alloweb浏览器字符串是：

• *webdriver
• *firefox-wd
• *iexplore-wd

所以我写了：

String browserString= "*firefox-wd"; 

而且解决了这个问题。
