There is an error which prevents any interactions to the page. Here is the relavant code for logging into twitter.com



~~~
try {
    WebClient webClient = new WebClient(BrowserVersion.BEST_SUPPORTED);
    webClient.getOptions().setThrowExceptionOnScriptError(false);


    HtmlPage page = webClient.getPage("http://twitter.com");

    ((HtmlElement) page.getFirstByXPath("//input[@name='session[username_or_email]']"))
            .type("myusername");

    ((HtmlElement) page.getFirstByXPath("//input[@name='session[password]']")).type("mypass");

    HtmlPage loggedinPage = ((DomElement) page.getFirstByXPath("//input[@value='Log in']")).click();

    System.out.println("Clicked login!");

    String pageAsXml = loggedinPage.asXml();

    System.out.println(pageAsXml);
} catch (Exception e) {
    e.printStackTrace();
}
