[Htmlunit-user] Noob Q

[John T. <jo...@jd...>]

Hi

I just downloaded HTLMUnit and am trying the very first example in the
tutorial, like this:

public class TestBug extends TestCase {
    public void testHomePage() throws Exception {
        final WebClient webClient = new WebClient();
        final URL url = new
URL("http://post.craigslist.org/sfo/R/res/eby/49");
        final HtmlPage page = (HtmlPage)webClient.getPage(url);
        assertEquals( "htmlunit - Welcome to HtmlUnit", page.getTitleText()
);
    }
}

but with a different URL: http://post.craigslist.org/sfo/R/res/eby/49

The example works with the original URL.

I get an exception. Any hints?
Thx,
