第一个servlet程序

费了很大一股劲;

Servlet.java

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

public class ServletTest extends HttpServlet {

    protected void doGet(HttpServletRequest request,
            HttpServletResponse response) throws ServletException, IOException {
        response.setHeader("Content-Type", " text/html; charset=utf-8");
        response.getWriter().println("庞静赢是个傻逼");
    }
}
