我是JSF新手,面临一个问题。我开发了一个包含标签的小应用程序
<h:inputText>
. 当我执行应用程序时,它不会显示文本输入部分。
代码如下:
使用者java:
(托管Bean)
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
}
