title: Shows exception in java code (Selenium + Jsoup)
body: <p>I am working on an project. In that, I have to get HTML page source code. For that, I invoke firefox driver using <code>Selenium</code>, and store page source code in String, and then parse using <code>Jsoup</code>  </p>
  
  <p>My code worked fine for single <code>url</code>. But when I put my code in testing, where it has to get numbers of URLS one by one, then at the end it throws one exception, and my project fails. Please see the exception and tell me why this occurs, and give me some solution to overcome this Exception.</p>
  
  <p><strong>My selenium code is as follows,</strong> </p>
  
  <pre><code>private static FirefoxProfile createFirefoxProfile() {
      File profileDir = new File("/tmp/firefox-profile-dir");
      if (profileDir.exists()) {
          return new FirefoxProfile(profileDir);
      }
      FirefoxProfile firefoxProfile = new FirefoxProfile();
      File dir = firefoxProfile.layoutOnDisk();
      try {
          profileDir.mkdirs();
          FileUtils.copyDirectory(dir, profileDir);
      } catch (IOException e) {
          e.printStackTrace();
      }
      return firefoxProfile;
  }
  </code></pre>
  
  <p><strong>// below code in main function (url1 and url2 are two urls )</strong></p>
  
  <pre><code>WebDriver driver = new FirefoxDriver(createFirefoxProfile());
  driver.get(url1);
  String hml1 = driver.getPageSource();
  driver.get(url2);
  String hml2 = driver.getPageSource();
  driver.close();
  </code></pre>
  
  <p><strong>Exception</strong> </p>
