Warning -> Failed to start: SocketListener , while performing Cross Browser Testing

Hello Everyone,

I have just started learning Selenium. I am trying to use Selenium RC for Cross Browser Testing.
While performing Cross Browser Testing I am getting error " Failed to start: SocketListener0@0.0.0.0:4444" in all the Browsers. Please give me a solution as soon as possible.

Thanks,

Make sure you have started the selenium server. Selenium Server runs on port 4444.
1) There can be another service which might be blocking this port. Eg skype or some other app.

2) If thats not the case, then selenium server might be already running. Please stop it with the help of following url and then try again.
localhost:4444/selenium-server/driver/?cmd=shutDownSeleniumServer

If this does not work, you can also use defaultselenium class to instantiate selenium. With defaultselenium class you can change the port number on which server is running.

hi,
i tried 2nd way but still, im having same error..
is it possible if it is a kind of jar problem ? maybe i added wrong jars ?
:S
thanks.

Shutdown PC.. Start after 1 minuet..
By Mistake you might have clicked on .jar file from selenium folder, that may be blocking you.
