struts不能创建formbean

忘记贴错误堆栈了，如下：

  1.   

    以上错误是访问login.jsp的时候出现的。login.jsp的内容如下：
    <%@ taglib uri="/tags/struts-bean" prefix="bean" %>
    <%@ taglib uri="/tags/struts-html" prefix="html" %>
    <%@ taglib uri="/tags/struts-logic" prefix="logic" %><html:html locale="true">
    <head>
    <title><bean:message key="welcome.title"/></title>
    <html:base/>
    </head>
    <body bgcolor="white"><html:form action="login.do" >
    <bean:message key="firstApp.form.login.username.inputPrompt"/>
    <html:text property="username"/><br>


    <bean:message key="firstApp.form.login.password.inputPrompt"/>
    <html:text property="passwd"/><br>
    <html:submit property="submit" value="ok"/>
    </html:form></body>
    </html:html>
      

  2.   


    改成<html:form action="/login" >
    看看先

    你配置文件actionMappings里的attribute属性呢？还有你的配置文件中的foward 里name 是loginSuccess，action里是success
