JSF 태그 <h:inputText>이 작동하지 않습니다.

저는 JSF를 처음 사용하면서 문제가 있습니다. 나는 <h:inputText> 태그를 포함하는 작은 응용 프로그램을 개발했습니다. 응용 프로그램을 실행할 때 텍스트 입력 부분이 표시되지 않습니다.JSF 태그 <h:inputText>이 작동하지 않습니다.

User.java : (Bean을 관리)

package com.JSF.UIExample; 

import javax.faces.bean.ManagedBean; 
import javax.faces.bean.RequestScoped; 

@ManagedBean(name = "user", eager = true) 
@RequestScoped 
public class User { 
    private String name; 
    private String password; 
    private String email; 
    private String gender; 
    private String address; 

    public User(){ } 
    // getter and setter 
}

답장을 보내 주셔서 감사 많이. 이전 네임 스페이스로 변경되었으며 나에게 잘 작동했습니다. –

나는 당신의 대답을 유용하다고 표시하게되어 기쁘 겠지만 같은 것을하기에 충분한 평판이 없다. –

좋은 것으로 표시했습니다. –
