Jsf 2 将同一EJB注入两个不同的托管bean不起作用

我有一个无状态EJB和两个不同的会话范围的托管bean

e、 g.EJB如下所示-

@Stateless
public classs MyEjb implements MyEjbLocal {
    @PersistentContext(unitName="myPU")
    private EntityManager em;

public MyBean2() {
    entities = myEjb.getAllEntities(); //this is where the problem is, myEjb is null
}

还有一个豆子-

@ManagedBean
@SessionScoped
public class MyBean1 implements Serializable {
    @EJB
    private MyEjbLocal myEjb;

@ManagedBean
@SessionScoped
public class MyBean2 implements Serilizable {
    @EJB
    private MyEjbLocal myEjb;

    private List<MyEntity> entities;

    public MyBean2() {
        entities = myEjb.getAllEntities(); //this is where the problem is, myEjb is null
    }

还有另一个托管bean-

@ManagedBean
@SessionScoped
public class MyBean1 implements Serializable {
    @EJB
    private MyEjbLocal myEjb;

@ManagedBean
@SessionScoped
public class MyBean2 implements Serilizable {
    @EJB
    private MyEjbLocal myEjb;

    private List<MyEntity> entities;

    public MyBean2() {
        entities = myEjb.getAllEntities(); //this is where the problem is, myEjb is null
    }

@ManagedBean
@会议范围
公共类MyBean2实现了可序列化{
@EJB
私人myEjb本地myEjb；
私人名单实体；
公共MyBean2（）{
entities=myEjb.getAllenties（）；//这就是问题所在，myEjb为null
}

我在page1中使用MyBean1，在page2中使用MyBean2。应用程序从page1开始，一切正常。但当我转到page2时，我收到一个异常，说容器无法初始化MyBean2

这就是我在搜索和谷歌搜索时发现的，我认为这是另一种情况，因为他正在将一个托管bean注入另一个托管bean

我知道一个可能的解决方案是创建两个不同的EJB。但我真的想知道为什么不能这样做，或者如果可以这样做，那么我可能做错了什么

我已经使用可嵌入容器测试了myEjb.getAllenties（）方法，它工作正常。myEjb被注入，我得到了所有的实体

多谢各位

更新：Stacktrace 对不起，这个堆栈太长了
