        // trying to get an access token without permitting the request token.
        try {
            twitter.getOAuthAccessToken(rt.getToken(), rt.getTokenSecret());
        } catch (TwitterException te) {
        }
        Map<String, String> props = new HashMap<String, String>();
        response = http.get(rt.getAuthorizationURL());
        cookie = response.getResponseHeader("Set-Cookie");
//        http.setRequestHeader("Cookie", cookie);
        props.put("Cookie", cookie);
        resStr = response.asString();
        authorizeURL = catchPattern(resStr, "<form action=\"", "\" id=\"oauth_form\"");
        params = new HttpParameter[4];
        params[0] = new HttpParameter("authenticity_token"
                , catchPattern(resStr, "\"authenticity_token\" type=\"hidden\" value=\"", "\" />"));
        params[1] = new HttpParameter("oauth_token",

        params[3] = new HttpParameter("session[password]", password);
        response = http.request(new HttpRequest(RequestMethod.POST, authorizeURL, params, null, props));
        resStr = response.asString();
        String pin = catchPattern(resStr, "<kbd aria-labelledby=\"code-desc\"><code>", "</code></kbd>");
        at = twitter.getOAuthAccessToken(rt, pin);     
    	return at;
    }
    
    
    private static String catchPattern(String body, String before, String after) {
        int beforeIndex = body.indexOf(before);
        int afterIndex = body.indexOf(after, beforeIndex);
        return body.substring(beforeIndex + before.length(), afterIndex);
