Hi , when ever I trying to run the Junit script on eclipse it prompts me an error. I have launched the server.  
I am using - “[http://http](http://http)://127.0.0.1:4723/wd/hub/” in the script ( Browser shows - That URL did not map to a valid JSONWP resource ). Need help what do in the following error.

org.openqa.selenium.remote.UnreachableBrowserException: Could not start a new session. Possible causes are invalid address of the remote server or browser start-up failure.
