表單未提交

我寫了一個簡單的JSF表單。問題是有一個我找不到的錯誤。當我打開主頁面並輸入用戶名和密碼時，頁面必須將我重定向到下一頁，但這不會發生。你能幫我找到我的錯誤嗎？表單未提交

這是主要的登錄JSF頁面

       </div> 
      </div>

這是託管bean

/** Bean for checking users and passwords. 
If the user enters the correct username and password 
the user will be redirected to main.xhtml 
If not the page will refresh. */ 

package com.dx.sr_57; 

import java.io.Serializable; 
import javax.enterprise.context.SessionScoped; 
import javax.inject.Named; 


@Named("loginController") 
@SessionScoped 
public class user_check implements Serializable { 
    private String user; 
    private String password; 

     public user_check(){ 
     } 

     public user_check(String user, String password){ 
      super(); 
      this.user = user; 
      this.password = password; 
     } 



     /** get the content of the variables from the JSF Login page */ 

     public String setUser(String newValue) { 
      user = newValue; 
      return user; 
     } 

     public String getUser(){ 
      return user;  
     } 

     public String setPassword(String newValue) { 
      password = newValue; 
      return password; 
     } 

     public String getPassword(){ 
      return password; 
     } 

     public String user_compare() {   
      return "success";   
     } 
}

你需要爲了得到JSF投入使用<h:form>組件和命令工作。

因此，通過

<h:form styleClass="login active"> 
    ... 
</h:form>

您還需要修復您的制定者是fullworthy制定者更換

<form class="login active"> 
    ... 
</form>

，否則你可能會面臨一個PropertyNotFoundException。

因此，通過

public void setUser(String newValue) { 
     user = newValue; 
    } 

    public void setPassword(String newValue) { 
     password = newValue; 
    }

無關更換

public String setUser(String newValue) { 
     user = newValue; 
     return user; 
    } 

    public String setPassword(String newValue) { 
     password = newValue; 
     return password; 
    }

到具體問題，HTML <center>標籤棄用自1998年以來和無效的XHTML嚴格。去掉它。您需要在<img>上設置CSS text-align: center。
