    java.text.SimpleDateFormat sdf = new java.text.SimpleDateFormat("yyyy");
    request.setAttribute("year", sdf.format(new java.util.Date()));
    request.setAttribute("tomcatUrl", "http://tomcat.apache.org/");
    request.setAttribute("tomcatDocUrl", "/docs/");
    request.setAttribute("tomcatExamplesUrl", "/examples/");

    <!DOCTYPE html>
    <html lang="en">
    
    <head>
        <meta charset="UTF-8">
        <meta name="viewport" content="width=device-width, initial-scale=1.0">
        <meta http-equiv="X-UA-Compatible" content="ie=edge">
        <title>Document</title>
    </head>
    
    <body>
        <%
            out.print("hello world!");
        %>
    </body>
    
    </html>

    第二种:

     在webapps新建一个子目录“helloJsp”,在“helloJsp”的目录下新建一个“index.jsp”(内容跟上面“test.jsp”一样)和一个“WEB-INF”子目录,在“WEB-INF”下新建“web.xml”(复制../../ROOT文件里“WEB-INF”即可)文件,和两个空间目录,“classes” “lib”,

      访问网址“http://localhost:8080/helloJsp/”
