HttpClient client = (HttpClient)session.getAttribute("org.apache.commons.httpclient.HttpClient");
if(client==null){
client = new HttpClient();
//使用POST方法登录
PostMethod post = new PostMethod(登陆页面地址);
post.addParameter(new NameValuePair("user","用户名"));
post.addParameter(new NameValuePair("pass","口令"));
client.executeMethod(post);
post.releaseConnection();
session.setAttribute("org.apache.commons.httpclient.HttpClient",client);
}
//打印服务器返回的状态

PostMethod get = new PostMethod("登陆后的页面"); client.executeMethod(get);
String body = get.getResponseBodyAsString();
response.getWriter().print(new String(body.getBytes("8859_1")));
get.releaseConnection();

//释放连接
