Java用POST传对象给Servlet

搜了很久，也没找到Java类里调用Servlet的例子，只好用Post方法传对象。

发送POST的例子在 ： http://lodachi.javaeye.com/?show_full=true

Java代码

　　package dbConn;　　import java.io.InputStream;　　import java.io.ObjectOutputStream;　　import java.io.OutputStream;　　import java.net.HttpURLConnection;　　import java.net.MalformedURLException;　　import java.net.URL;　　import bean.Tick;　　import flex.messaging.util.URLEncoder;　　public class TestAction {　　public static void main(String[] args) throws Exception{　　TestAction test = new TestAction();　　test.test();　　}　　public void test() throws Exception {　　URL url = new URL("http://localhost:8080/HRC/servlet/DataPushServlet");　　HttpURLConnection urlConn = (HttpURLConnection) url.openConnection();　　urlConn.setDoOutput(true);　　urlConn.setDoInput(true);　　urlConn.setUseCaches(false);　　urlConn.setRequestProperty("Content-type","application/x-java-serialized-object");　　urlConn.setRequestMethod("POST");　　urlConn.connect();　　OutputStream outStrm = urlConn.getOutputStream();　　ObjectOutputStream oos = new ObjectOutputStream(outStrm);　　Tick tick = new Tick();　　oos.writeObject(tick);　　oos.flush();　　oos.close();　　InputStream inStrm = urlConn.getInputStream();　　}　　}
