Eclipse JSF项目中的错误注入EJB

大家好，我是JavaEE新手，我想用EJB和JSF开发一个应用程序，当我想在WebDynamicque项目中注入我的JAR时，我遇到了这个错误，我什么都不懂，请任何人都帮我

    ]
}

这是DAO的接口：

package com.bestofgeeks.gestion.dao; 

import java.util.List; 
import javax.ejb.Local; 
import com.bestofgeeks.gestion.entity.products; 

@Local 
public interface IGestion { 
  public void delete(products p); 
  public products persiste(products p); 
  public List<products> selectAll(); 
} 

还有我的jsf项目 我创建了一个控制器 这是密码

    package com.bestofgeeks.gestion.controllers;

import javax.annotation.ManagedBean;
import javax.ejb.EJB;
import javax.enterprise.context.RequestScoped;


import com.bestofgeeks.gestion.services.Iservices;

@RequestScoped @ManagedBean
public class myProduct {
@EJB
    public String name = "noredine";

    Iservices service;







}

必须注入本地接口，而不是bean：

@EJB
IGestion product;

正如@kukeltje在评论中所说：

阅读错误：（emphasis mine）“找不到类型为的接口的EJB 'com.bestofgeeks.gestion.dao.Implement.GestionDAOBean'以及它是什么 引用是一个impl，而不是

界面

你可以发布一些代码吗？请添加更多这还不足以帮助你。并请将其添加到不在评论中的问题中。请按其下方的“编辑”按钮编辑您的问题，而不是将其添加到评论中。这里没有与JSF相关的代码，jpa和JavaEE也不是太广泛。尝试创建一个读取错误：（emphasis mine）“找不到类型为'com.bestofgeeks.gestion.dao.Implement.GestionDAOBean'的接口的EJB”，它引用的是impl，而不是接口！正如错误中明确指出的（正如我所评论的）。也许在答案中加上这一点，让其他“学习”阅读错误，因为它们大多非常明确
