朋友，你们好，用j2sdk1.4.2和tomcat5.0在运行程序如下：

<%@ page session="false"%>

<font size=4> <ul> <li> Day of month: is <jsp:getProperty name="clock" property="dayOfMonth"/> <li> Year: is <jsp:getProperty name="clock" property="year"/> <li> Month: is <jsp:getProperty name="clock" property="month"/> <li> Time: is <jsp:getProperty name="clock" property="time"/> <li> Date: is <jsp:getProperty name="clock" property="date"/> <li> Day: is <jsp:getProperty name="clock" property="day"/> <li> Day Of Year: is <jsp:getProperty name="clock" property="dayOfYear"/> <li> Week Of Year: is <jsp:getProperty name="clock" property="weekOfYear"/> <li> era: is <jsp:getProperty name="clock" property="era"/> <li> DST Offset: is <jsp:getProperty name="clock" property="DSTOffset"/> <li> Zone Offset: is <jsp:getProperty name="clock" property="zoneOffset"/> </ul> </font>

</body> </html> 时，出现错误提示，

HTTP Status 500 -

note The full stack trace of the root cause is available in the Tomcat logs.

上面程序即为，tomcat5.0中所带例子jsp-examples中的dates/data.jsp 问题出在其在例子中运行时成功，而在把它改名后放在root下时却不行了，请指教。

另：朋友，我是新手，但对jsp学习有强烈欲望，希望和你们成为朋友，以后共同探讨，我的ＱＱ是１１３０８３８６７。
