送分！初级问题，tomcat报错。(50分)

zky88 · 2006-05-25

http://127.0.0.1:8080/jsp-examples/num/numguess.jsp可以正常打开页面，
http://127.0.0.1:8080/jsp-examples/num/123.jsp时tomcat报错，
我的123.jsp:
<%@ page contentType="text/html;
charset=gb2312"
language="java"
import="java.sql.*"
errorPage=""
%>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type"
content="text/html;
charset=gb2312"
/>
<title>无标题文档</title>
</head>
<body>
Hello! The time is now <%= new java.util.Date() %>
</body>
</html>
我跟 numguess.jsp放在相同目录的，123.jsp就不行，报错如下：

１、你的123.jsp可能编码有问题
２、把你的tomcat安装目录中的work中的文档删除，清空tomcat的缓存看看

看这句好像是jdk没配置好，网上关于jdk和tomcat配置很多，照着做应该没有问题

同意楼上。

同意楼上，你在123上调用了java.util.Date() ，你把这个函数去了。
刚学jsp没超过24hour

yangxiao_jiang · 2006-06-16

你用 java.util.Date()
但是没有 import="java.sql.*"
进来，当然会错

同意楼上
