为什么出现org.apache.jasper.JasperException: Cannot find message resources under key org.apache.struts.action.MESSAGE这个错误?
jsp页面
<%@ taglib uri="/WEB-INF/struts-html.tld" prefix="html"%>
<html:html>
<html:errors/>
<body>
<html:form action="/login" focus="userName">
<table>
<tr>
<td>user Name:</td>
<td><html:text property="userName"/></td>
