In addition to previous post.

I am able to view the Hub console on browser and it shows
h2. Available Remote Controls as "*chrome"
If this could be the issue, please help me in editing the example files, so far I have not changed anything on this test.

The error log with full stack is:

HI,

I edited the build.xml and replaced "*firefox" with "*chrome" and the test is ran successfully. {emoticon:__jive_emoticon_name=happy}

But somebody got the idea, why this happens?

I have no idea since I am newbie on Selenium. {emoticon:__jive_emoticon_name=silly}
Thanks,
Anoop
