私はシンプルなjsfログインアプリケーションを持っています。サーブレットjspのServlet.service（）が例外をスローしましたjava.lang.RuntimeException：FacesContextが見つかりません
私のlogin.jspが
<%@ page contentType="text/html"%>
<%@ taglib uri="http://java.sun.com/jsf/core" prefix="f"%>
<%@ taglib uri="http://java.sun.com/jsf/html" prefix="h"%>
<f:view>
<html>
<head>
<title>JSF Login Application</title>
</head>
<body>
<h:form>
<table>
<tr>
<td><h:outputText value="Enter Login ID: " /></td>
<td><h:inputText id="id" value="#{LoginBean.loginid}" /></td>
</tr>
<tr>
<td><h:outputText value="Enter Password: " /></td>
<td><h:inputSecret id="pwd" value="#{LoginBean.pwd}" /></td>
</tr>
<tr>
<td> </td>
<td><h:commandButton value="Login" action="#{LoginBean.CheckValidUser}" /></td>
</tr>
</table>
</h:form>
</body>
</html>
</f:view>
マイLoginBeanが
public class LoginBean{
String loginid;
String pwd;
public LoginBean(){}
public String getLoginid(){
return loginid;
}
public void setLoginid(String loginid){
this.loginid = loginid;
}
public String getPwd(){
return pwd;
}
public void setPwd(String pwd){
this.pwd = pwd;
}
public String CheckValidUser()
{
if(loginid.equals("username") && pwd.equals("password"))
{
return "success";
}
else
{
return "fail";
}
}
}
ですし、私のweb.xmlがbにあるようです
<web-app>
<display-name>JSFLoginAppln</display-name>
<context-param>
<param-name>javax.faces.STATE_SAVING_METHOD</param-name>
<param-value>server</param-value>
</context-param>
<welcome-file-list>
<welcome-file>login.jsp</welcome-file>
</welcome-file-list>
</web-app>
です展開中に例外をスローしないため、展開中は問題ありません。しかし、私はJBOSSサーバ上で実行すると、それは次の例外

おかげで私を助けてください！
LoginBeanをManagedBeanとしてマークするのを忘れましたか？ –
