/empty/PostMsg.jsp:15: Class _empty.FileWriter not found.
FileWriter fw = new FileWriter(path + "\\DataFile\\Message.inc", true);

PostMsg.jsp文件其中一段代码:
001 <%@ page contentType="text/html; charset=GB2312"%>
002 <HTML>
003 <HEAD>
004 <TITLE>访客留言版</TITLE>
005 </HEAD>
006 <BODY>
007 <CENTER>
008 <FONT SIZE = 5 COLOR = blue>访客留言版</FONT>
009 </CENTER>
010 <HR>
011 <%
012 String path = request.getRealPath(".");
013 //取得目前目录在伺服端的实际位置
014
015 FileWriter fw = new FileWriter(path+ "\\DataFile\\Message.inc",true);
016 //建立FileWrite对象,设置由fw对象变量引用, 并以Append方式写入资料
017
018 BufferedWriter bw = new BufferedWriter(fw);
019 //建立BufferedWriter对象,并设置由bw对象变量引用
请教各位大哥大姐,这是怎么回事呀??
