我的web.xml是

谁能帮我修一下这个

提前感谢

我刚刚从我的项目库中删除了

jsfapi

和

jsf imp

，并插入了

<listener>
    <listener-class>com.sun.faces.config.ConfigureListener</listener-class>
</listener>


com.sun.faces.config.ConfigureListener

在

web.xml

中，因为我在创建项目时让Eclipse运行时环境

jBoss

。

您是否忘记将您的登录域标记为ManagedBean？@Mr.J4mes:我已经标记了它。LoginBean com.bean.LoginBean请求这不是问题所在。阅读Mithun的重复问题链接获取答案。
