我的代码是（newfile.jsp）：

<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
    pageEncoding="ISO-8859-1"%>
<%@ page import="java.io.*,java.util.*, javax.servlet.*" %>    
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Insert title here</title>
</head>
<body>

<form name="myform" action="game.jsp" method="post" enctype="multipart/form-data">

在上一次导入中，您添加了额外的，，这使得编译器需要另一次导入，请使用：

 <%@ page import="java.io.*,java.util.*, javax.servlet.*" %>
