Answer 1

1 抓错了呗，把代码贴一下看看
2 对方发现有扒手，拒绝提供。 类似QQ的图片空间。3 你测试抓取 sina 的新闻看看。 如果能用，程序就没问题啦！

Answer 2

我用了新浪的.试了一下那个HttpClient的演示程序.也还是不成功.代码如下:package myhttpclient;import java.io.IOException; 
import org.apache.commons.httpclient.*; 
import org.apache.commons.httpclient.methods.*; 
/** 
 *最简单的HTTP客户端,用来演示通过GET或者POST方式访问某个页面
  *@authorLiudong
*/public class SimpleClient {
public static void main(String[] args) throws IOException 
{
  HttpClient client = new HttpClient(); 
      // 设置代理服务器地址和端口             //client.getHostConfiguration().setProxy("proxy_host_addr",proxy_port); 
      // 使用 GET 方法 ，如果服务器需要通过 HTTPS 连接，那只需要将下面 URL 中的 http 换成 https 
         HttpMethod method=new GetMethod("http://finance.sina.com.cn/chanjing/b/20080415/07584749699.shtml");
      //使用POST方法
      //HttpMethod method = new PostMethod("http://java.sun.com");
      client.executeMethod(method);      //打印服务器返回的状态
       System.out.println(method.getStatusLine());
      //打印返回的信息
      System.out.println(method.getResponseBodyAsString());
      //释放连接
      method.releaseConnection();
   }
}
异常如下:13:12:38,484  INFO HttpMethodDirector:434 - I/O exception caught when processing request: finance.sina.com.cn
13:12:38,484  INFO HttpMethodDirector:440 - Retrying request

你们公司是用代理上网吗？
要是的把代理配好。
client.getHostConfiguration().setProxy("代理的ip地址",代理的端口);
如：client.getHostConfiguration().setProxy("192.168.0.254",80);我们公司代理上网的程序里不配代理我也连不上，程序里配置了代理才可以。
