这是浏览器出错信息,无法准确反映问题,需要打开tomcat的日志或log4j的输出日志,找到第一个ERROR,当然tomcat控制台也可能会找到。

一般都是数据库连接问题。

tomcat控制台里是开始是这样的错误信息:

2007-10-18 21:15:32,796 [http-8080-Processor25] ERROR StandardWrapper[/jpetstore

:action] - Servlet.service() for servlet action threw exception

javax.servlet.jsp.JspException: Define tag cannot set a null value

是什么意思呀?怎么解决?

谢谢banq大哥这么及时帮忙.
