    private static String renRenLoginURL = "http://www.renren.com/PLogin.do";

    // The HttpClient is used in one session
    private HttpResponse response;
    private DefaultHttpClient httpclient = new DefaultHttpClient();

    private boolean login() {
        HttpPost httpost = new HttpPost(renRenLoginURL);
        // All the parameters post to the web site
        List<NameValuePair> nvps = new ArrayList<NameValuePair>();
        nvps.add(new BasicNameValuePair("origURL", redirectURL));
        nvps.add(new BasicNameValuePair("domain", "renren.com"));

兄弟，你的代码存在以下问题：
1、登陆可以???我说不可以！你看下你自己的代码login方法，除了因为网络异常或者Server返回500错误产生Exception的时候return false外，你总是return true，就是说是你自己认为登录成功了，结果未必是成功的。
2、要做好爬虫一定要先熟悉HTTP协议，每次请求Server会返回StateCode，如果StateCode为302、303之类的，你还需要把Location头取出来，再次请求，虽然HttpClient有时候能帮助我们做。你的update()方法得到的StateCode为302还需要再请求一下Location Header。
3、有时候你还要解析页面结果，一般用正则表达式进行，当然你也可以用HTMLParser，比如说，当你输错了密码，在你的程序里不会有任何的提示，你需要把登录的提示Parser出来然后返回提示。
