HtmlUnitDriver does not appear to be loading page

HtmlUnitDriver does not appear to be loading page

I'm trying to get HtmlUnitDriver to work in my development environment. As
a beginner, I've tried implementing the example from the following page
using the latest selenium server jar:
http://code.google.com/p/selenium/wiki/GettingStarted
Unfortunately, whenever I try to run this program, I get the following
exception:
Exception in thread "main" org.openqa.selenium.NoSuchElementException:
Unable to locate element with name: q

I've tried modifying my code to incorporate the fixes implemented here:
HtmlUnitDriver causes problems while getting an url
I've tried getting the URL of the page using driver.getCurrentUrl() after
the call to driver.get("http://www.google.com"), but the string that is
returned is about:blank.
Similar code in this example would definitely work if I were to run it
using FirefoxDriver, but to meet requirements, I need my script to run
headless with selenium.
Any help would be greatly appreciated.
