Please get me out of this.

Thanks,

Hi manoj,

You can try the following code

HtmlUnitDriver driver = new HtmlUnitDriver();
driver.setJavascriptEnabled(true);

Notwithstanding other considerations above, it is possible to get HtmlUnitDriver to emulate a specific browser. You should not really be doing this, as web-applications are better coded to be neutral of which reasonably recent browser you are using. There are two more constructors for HtmlUnitDriver that take allow us to indicate a browser to emulate. One takes a browser version directly:

HtmlUnitDriver driver = new HtmlUnitDriver(BrowserVersion.FIREFOX_3);

Thanks
Divya

Hi Divya,

Thank you :) its working now.
FireFox version was a problem.
i used
HtmlUnitDriver driver = new HtmlUnitDriver(BrowserVersion.FIREFOX_17);
driver.setJavascriptEnabled(true);
