Question

尝试运行servlet时，我遇到了标题上显示的错误。

我不使用日食或任何思想，因为我明确不应该将其用于这项任务。

正在运行的代码是包com.mkyong;

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

public class ServletDemo1 extends HttpServlet{

    public void doGet(HttpServletRequest request, HttpServletResponse response)
    throws IOException{
        PrintWriter out = response.getWriter();
        out.println("<html>");
        out.println("<body>");
        out.println("<h1>Hello Servlet Get</h1>");
        out.println("</body>");
        out.println("</html>"); }
}

我的web.xml文件看起来像

<?xml version="1.0" encoding="UTF-8"?>

<!-- web-app version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee" 
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee 
http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd" -->

<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

              http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
         version="2.5"
         xmlns="http://java.sun.com/xml/ns/javaee">

    <servlet>
        <servlet-name>Servlet Name For Demo1</servlet-name>
        <servlet-class>com.mkyong.ServletDemo1</servlet-class>
    </servlet>

    <servlet-mapping>
        <servlet-name>Servlet Name For Demo1</servlet-name>
        <url-pattern>/Demo1</url-pattern>
    </servlet-mapping>
</web-app>

localhost_access_log的内容为：
