jsp때와 마찬가지로 데이터전송은 get방식과 post방식이 있습니다.


그래도 데이터가 공개되는 get방식보단 post방식을 사용하겠습니다.


먼저 login.jsp 이라는 jsp파일을 하나 생성합니다.


<%@ page language="java" contentType="text/html; charset=UTF-8"
	pageEncoding="UTF-8"%>
<%
	request.setCharacterEncoding("euc-kr");
	String name = request.getParameter("name");
%>
<% out.print(name); 

System.out.println("login.jsp 호출됨");%>


액티비티에서 데이터 name을 보낼 예정이고, 다시 name이라는 출력결과를 가져갈 예정입니다.

그리고 접근이 되면 'login.jsp 호출됨' 이라고 서버에 출력이 됩니다.

이제 서버와 연결이기 때문에


StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
 

StrictMode.setThreadPolicy(policy);

이 코드를 사용할 예정입니다. 안그러면 오류나요~


우선

activity_main.xml
