帮忙找个错误。急！
报错如下：
Servlet.service() for servlet action threw exception
javax.servlet.jsp.JspException: Cannot find bean source in any scope
我jsp页面代码只要加上 <html:```> tag就会报上面的错误.

[解决办法]
你的后台怎么写的
在session中保存了“source”吗
[解决办法]
要看看 后台才知道
[解决办法]
你的web.xml配置好了么
[解决办法]
是不是标签库没导进去？
使用本地的看看
[解决办法]
用什么框架做的，导.jar包了吗？用的myeclipse插件？
好长的代码啊，能把错误信息发上来不？
[解决办法]
javax.servlet.jsp.JspException: Cannot find bean source in any scope
错误是说你指定的BEAN在你所指定的共享区域找不到
也就是你在使用STRUTS标签时候如果你在session 而用的时候把对象存在了request上 这样就会报这个错
