GAE and HtmlUnit 2.9 - getting exception upon jsxGet_cookie

I'm trying to login to google using HtmlUnit in an app in GAE. However, I keep getting this error:

Exception invoking jsxGet_cookie

Which is because

This occurs 开发者_如何学Cwhen running in GAE and in my computer.

Has anybody ever seen this kind of error before? How can I change the default Port? Are there any workarounds?

Change the URL you are fetching to include the default port 80. Example: http://www.cnn.com becomes http://www.cnn.com:80. There's also a workaround involving overriding classes but I prefer to clarify the URL.

I had that problem at first (I have a GWT+GAE app) and I was using this very simple code and I got the js cookie exception and the port:-1 exception

    WebClient webClient = Holder.get();
    HtmlPage page=null;

    try {
        page = webClient.getPage(url);
        System.out.println("CRAWLER DONE");
    } catch (FailingHttpStatusCodeException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (MalformedURLException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

     // appengine hack because it's single threaded


    String pageContent = page.asXml();
    webClient.closeAllWindows();
    return pageContent;

then I tried the following,

    webClient.setCssEnabled(false);
    webClient.setThrowExceptionOnFailingStatusCode(false);
    webClient.setThrowExceptionOnScriptError(false);

And it just miracusly worked. cheers.
