I dont know whats wrong here and its displaying the following error

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/python2.7/site-packages/selenium-2.21.3-py2.7.egg/selenium/webdriver/firefox/webdriver.py", line 51, in __init__

    self._get_firefox_output())
selenium.common.exceptions.WebDriverException: Message: 'The browser appears to have exited before we could connect. The output was: Error: cannot open display: :1100\n' 

Can any please let me know how to solve this ..............

Answer 1

The error says"cannot open display: :1100". Are you running it on a remote terminal? Make sure you can type "firefox" at the prompt and have the browser open (that is what Webdriver does - opens Firefox on your system and then trying to connect to it). If you are running it on a remote system, do a web search on connecting to X display remotely.
