import java.io.IOException;
import java.io.PrintWriter;

import javax.servlet.ServletContext;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;

import javax.servlet.http.HttpServletResponse;

//ServletContext示例
public class ServletDemo6 extends HttpServlet {

public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {

         //得到ServletContext的方式1：
ServletContext context=this.getServletConfig().getServletContext();

//得到ServletContext的方式2：
context=this.getServletContext();
}

public void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {

doGet(request,response);
