Merging to an existing issue.

At the mement, you can extend RemoteWebDriver and override startSession method like
this:

  @Override
  protected void startSession(Capabilities desiredCapabilities) {
    String sid = getPreviousSessionIdFromSomeStorage();
    if (sid != null) {
      setSessionId(sid);
      try {
        getCurrentUrl();
      } catch (WebDriverException e) {
        // session is not valid
        sid = null;
      }
    }
    if (sid == null) {
      super.startSession(desiredCapabilities);
      saveSessionIdToSomeStorage(getSessionId().toString());
    }
  }

I was able to do it this way up until around build 2.17 or so.  Now it no longer works,
and I am trying to figure out why.  Here was the code that used to work for me (attached).

For me also ReusableFirefoxDriver.java worked until 2.25 version, where implementation
of ExtensionConnection method (it is overwritten in ReusableFirefoxDriver class)of
FirefoxDriver class is changed.

Did somebody find the solution?

If you want to use webdriver this way, why you are not saving its value into a static
var or into a single_ton class so that you are not instantiating it multiple times
?

Hi hakku,
How to save webdriver's value into a static var or single_ton?
May you share your code?

Thanks a million!

this should solve the issue ,how to access the selenium browser session:
WebDriver  driver=new RemoteWebDriver(new URL("http://localhost:7055/hub"), DesiredCapabilities.firefox());
        driver.get("http://www.google.com");

Abovementioned ReusableFirefoxDriver works with latest Selenium (2.42.2). All you need
is to override method
    void startSession(Capabilities, Capabilities) 
as well.

Please Anyone have a working sample for attaching existing browser in Internet explorer
