Unable to compile 注意：sun.tools.javac.Main 已过时???

今天安装了JDK+TOMCAT 测试了一个书上的计数器居然发现出现如下的错误
org.apache.jasper.JasperException: Unable to compile 注意：sun.tools.javac.Main 已过时。
C:\java\jakarta-tomcat\work\DEFAULT\ice\counterJavaBeanJsp_1.java:4: 在 import 中未找到类 Counter。
import Counter;

没有编译的JAVA代码Counter.class
[CODE]public class Counter{
long Count=0;
public long getCount()
{
return Count;
}
public synchronized long setCount()
{
Count++;
return Count;
}

}[/CODE]

还有JSP文件源码
[CODE]<%@ page contentType="text/html;charset=GB2312"%>
<%@ page import="Counter"%>
<jsp:useBean id="counter" class="Counter" scope="application">
</jsp:useBean>
<html>
<head>
<title>jishuqi</title>
<body>
<%
if (session.isNew())
counter.getCount();
%>
<p>
<p>
<%=counter.getCount()%>
</body>
</html>[/CODE]
