I am downloading the trunk as of 22/05/2011 and building with 'go
release'. I'm then navigating to 'build\java\server\src\org\openqa\grid
\selenium' and launching a hub from there with the following command
line:
java -jar selenium-standalone.jar -role hub

Currently I am testing with a grid machine as the local one. So I run
another instance locally except this time of a webdriver which
connects to the hub I just launched:
java -Dwebdriver.chrome.driver="C:\Users\Mike\Desktop
\chromedriver.exe" -jar selenium-standalone-jar -role webdriver -port
12345 -hub http://localhost:4444/grid/register

Going to http://localhost:4444/grid/console in a browser, I can see
one WebDriverRemoteProxy supporting 5 concurrent tests from 5
firefoxs, 1 internet explorer and 1 chrome. I am using the following
code from an eclipse project:
public class Grabber {
public static void main(String[] args) throws MalformedURLException
{
RemoteWebDriver driver = new RemoteWebDriver( new URL("http://
localhost:4444/grid/driver"),
DesiredCapabilities.internetExplorer() );
driver.get("http://www.google.com");
driver.quit();
}
}

Having the DesiredCapabilities as Chrome or Firefox works perfectly.
Having it as Internet Explorer gives the following error:

Exception in thread "main" org.openqa.selenium.WebDriverException:
<html>
<head>
<title>Error 500 cannot find : {platform=WINDOWS,

I also tried running the connecting webdriver as :
java -Dwebdriver.chrome.driver="C:\Users\Mike\Desktop
\chromedriver.exe" -jar selenium-standalone.jar -role webdriver -port
12345 -hub http://localhost:4444/grid/register -browser
browserName="internet explorer"

Going to the console I can see one internet explorer instance is
available. Running the eclipse code generates the same exception
however.

If it's relevant I am running on windows 7 and I have IE9 installed.
The following code works fine on the local machine:
public static void main(String[] args) throws MalformedURLException
{
WebDriver driver = new InternetExplorerDriver();
driver.get("http://www.google.com");
driver.quit();
}

Is there something I'm doing wrong or is this a known bug?

Hi Mike,

I've noticed that by default, a remote webdriver client on Windows 7
registers Internet Explorer as platform=VISTA.

Either you'll need to specify this platform in your
DesiredCapabilities object, or, I'd recommend manually setting your
platform when you start your remote client. Something similar to:

java -jar "c:\se\selenium-standalone.jar" -role webdriver -port 5555 -
hub http://se-hub:4444/grid/register -browser "-browserName=internet
explorer,version=9,platform=windows"

Hope that helps,
-Brad
