server端的代码

package hb.servlet;

import java.io.IOException;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

public class DojoAjax extends HttpServlet {
	
	protected void doGet(HttpServletRequest request,HttpServletResponse response) throws ServletException,IOException {
		System.out.println("do get");
	}

	
	protected void doPost(HttpServletRequest request,IOException {
		System.out.println("do post");
	}

}
