今天使用 <html:messages> 在JSP页面上显示消息：
ACTION文件
ActionMessages actionMessages = new ActionMessages();
actionMessages.add( "messageReplySuccess ", new ActionMessage( "messager.action.messageReply.messageReplySuccess "));
saveMessages(request, actionMessages);
return mapping.findForward( "success ");
JSP文件
<html:messages id= "notice " property= "messageReplySuccess " message= "true ">
<bean:write name= "notice "/>
</html:messages>
struts-config.xml
<!--message reply initial-->
<action path = "/mesReplyInit "
type = "messager.messageReply.MessageReplyInitAction "
name = "messageReplyForm "
scope = "session "
validate = "false "
input = "/jsp/MessageAdmin.jsp ">
<forward name= "success " path= "/jsp/MessageReply.jsp " />
<forward name= "fail " path= "/jsp/MessageReply.jsp " />
</action>
<!--message reply -->
<action path = "/messageReply "
type = "messager.messageReply.MessageReplyAction "
name = "messageReplyForm "
scope = "session "
validate = "true "
input = "/jsp/MessageReply.jsp ">
<forward name= "success " path= "/jsp/MessageReply.jsp " />
<forward name= "fail " path= "/jsp/MessageReply.jsp " />
</action>
画面启动过程是：先走一个初始化ACTION，然后到JSP画面，用户点击按钮提交后进入
另一个ACTION（在这个ACTION里把ACTIONMESSAGE加到request），然后返回这个画面。
错误提示：
javax.servlet.ServletException: Cannot find bean: "notice " in any scope

大家帮我看看是哪里出了问题。
同样的方法在另一个画面都可以使用，不同的是那个画面打开钱没有经过初始化ACTION，但这不会影响啊。
