httpUnit class not found

I am trying httpUnit for the first time and just trying to get a response back from google.com.

However, I keep getting the following error:

com.meterware.httpunit.dom.HTMLDocumentImpl not found

Though, I have placed httpUnit.jar in the libraries folder of my NetBeans project and can actually see that class file is there.

Any experiences with this?

It may have to do with the documented external dependencies of HttpUnit.
