JSP页面中嵌入代码，编译报错！解决办法_Java Web开发

JSP页面中嵌入代码，编译报错！！！！

Java code

<%@ page language="java" import="java.util.*" pageEncoding="GBK"%><%String path = request.getContextPath();String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";%><%@ page import="com.alipay.services.*"%><%@ page import="com.alipay.util.*"%><%@ page import="java.util.HashMap"%><%@ page import="java.util.Map"%><!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"><html>  <head>    <base href="<%=basePath%>">        <title>My JSP 'MyJsp.jsp' starting page</title>        <meta http-equiv="pragma" content="no-cache">    <meta http-equiv="cache-control" content="no-cache">    <meta http-equiv="expires" content="0">        <meta http-equiv="keywords" content="keyword1,keyword2,keyword3">    <meta http-equiv="description" content="This is my page">    <!--    <link rel="stylesheet" type="text/css" href="styles.css">    -->    <%        String test = "";        TestJava.getTestString();    %>      </head>    <body>      </body></html>

JSP页面代码。

<%@ page import="com.alipay.util.*"%>这已经引入 TestJava这个类了。

Java code

package com.alipay.util;public class TestJava {        public static String getTestString() {        return "TestString";    }    }

报错信息：
org.apache.jasper.JasperException: Unable to compile class for JSP:

31: <body>
32: <%
33: String test = "";
34: TestJava.getTestString();

请教~~~

------解决方案--------------------
<%@ page import="com.alipay.services.*"%>
<%@ page import="com.alipay.util.*"%>
<%@ page import="java.util.HashMap"%>
<%@ page import="java.util.Map"%>

把這些放在第一行吧，如果可以，嘗試看下jsp翻譯后的java文件，或許能看出什麽來。
------解决方案--------------------

探讨

<body>
<%
Test.getTestString();
System.out.println(Test.getTestString());
%>
</body>
这样
