当我运行 selenium 脚本时,我遇到了这个问题:(我在 tomcat 中运行这段代码,这是我遇到异常的时候,但在普通的 eclipse 中这工作得很好)
**org.openqa.selenium.WebDriverException: org.openqa.selenium.WebDriverException: Failed to connect to binary FirefoxBinary(/opt/firefox/firefox-bin) on port 7055; process output follows:**

代码:
String url = "google.com";
WebDriver driver = new FirefoxDriver();
String str ="";
driver.get(url);
driver.wait(10000);
str = driver.getPageSource();
System.out.println(str);
driver.close();
