Selenium Webdriver - Issue with FirefoxDriver on Debian Lenny (Error No display)

I am using Selenium to test my website, it opens up a URL using Firefox, logins and does some stuff on the page and then logs out and shuts firefox. That all works great on Windows 7. The code starts with:

WebDriver driver = new FirefoxDriver();
driver.get(URL);

Now I deployed my jar in linux box that runs Debian lenny which has iceweasel on it. A cron job starts the program which throws the following error when trying to open firefox:

org.openqa.selenium.firefox.NotConnectedException: Unable to connect to host 127.0.0.1 on port 7055 after 45000 ms. Firefox console output: Error: cannot open display: :0 Error: cannot open display: :0

I have Xvfb running ok in the box and I have set variable DISPLAY to 0. I have searched around and none of the solutions (like setting the env variable) worked.

Isnt XVfb supposed to work as a non-graphical environment that the browser will launch into and do the necessary actions? What's stopping it from starting up?

I am using the latest Selenium version 2.31 and Firefox 3.0.6 Iceweasel.

Edit: Updated to Firefox 14 and still see the same issue. I even raised the timeout limit to 60 seconds.

driver.manage().timeouts().pageLoadTimeout(60, TimeUnit.SECONDS);

SOLVED: By running it with the xvfb wrapper, xvfb-run like this:

export DISPLAY=:0.0
xvfb-run --auto-servernum --server-num=0 nohup java - jar X.jar

I have seen the similar issue and this is coming only for firefox, for other browser everything was working fine, I tried on Chrome. Here is the solution for this 1. Check the version of FF, if it is latest, then go for a lesser version of FF. It is recommended for more stability. 2. And you should always try to take latest selenium binary from selenium website.

Either try to update your webdriver or downgrade your firefox. this issue is related that selenium server cannot connect to your firefox.
