JSFで、マネージビーンに画面の値が反映されない

MyFacesを使って開発をしています。画面からの入力値が、マネージドビーンへうまく値設定できません。JSP側とManagedBean側へ値を受け渡すための設定である、faces-config.xml、マネージドビーンの設定は何度見直してもあっています（コピー、ペーストで入力してます）。値が反映されない理由がわからないのですが、コンソール上に、次のエラーが出力されます。
宜しくお願いします。

マネージドビーンは次の通りです。

public class RegistUserManagedBean implements Serializable{

private static final long serialVersionUID = -3090629182234182743L;

//利用者ID
private String userId;

//利用者名
private String userName;

//パスワード
private String password;

//利用者権限[選択値]
private String userKbn;

public String getPassword() {
return password;
}

public void setPassword(String password) {
this.password = password;
}

public String getUserKbn() {
return userKbn;
}

public void setUserKbn(String userKbn) {
this.userKbn = userKbn;
}

public String getUserId() {
return userId;
}

public void setUserId(String userId) {
this.userId = userId;
}

public String getUserName() {
return userName;
}

public void setUserName(String userName) {
this.userName = userName;
}

public String addUserInfoEvt(){

System.out.println(password);
System.out.println(userName);

//パスワード[0-9,a-z,A-Z,-,_]のいずれか
Pattern p = Pattern.compile("[0-9a-zA-Z|[-]|[_]]+");
Matcher m = p.matcher(password);
if(!m.matches()) {
Message.addErrMessage("userRegist_err03");
return "error";
}

//パスワード[4桁-8桁で収まっているかのチェック]
if((password.length() > 8) || (password.length() < 4)){
Message.addErrMessage("userRegist_err04");
return "error";
}

画面側のコード次のようになっています。

<html>
<body>
<f:view>
<br>
<br>
<h:outputText>利用者名、パスワード、利用者区分を入力して下さい。</h:outputText>
<h:form>
<blockquote>
<table cellpadding="2">
<tr>
<td><h:outputText value="利用者名：" /></td>
<td><h:inputText id="利用者名" required = "true" value="#{registUserManagedBean.userName}" maxlength="20" /></td>
</tr>
<tr>
<td><h:outputText value="パスワード：" /></td>
<td><h:inputText id="パスワードa" required = "true" value = "#{registUserManagedBean.password}" maxlength="8" /></td>
</tr>
<tr>
<td><h:outputText>利用者区分：</h:outputText></td>
<td>
<h:selectOneMenu value="#{registUserManagedBean.userKbn}" >

</h:selectOneMenu>
</td>
