java Bean石英注入空指针异常

Question

我遇到了一个问题，在Quartz schedule作业中注入CDIBean。我在quartz中为我的接口添加了自定义CDIJobFactory。当quartz方法在Jboss eap 6.4上执行时，它是抛出错误

java.lang.IllegalArgumentException: JobFactory cannot be set to null!

最初，我尝试使用EJB定时器（@Schedule annotation），但EJB定时器不起作用，控制台也没有任何问题，所以我不知道如何进一步使用EJB定时器，然后我开始使用quartz

所以，如果我在quartz中错过了什么或者做错了什么，请告诉我，因为我对quartz、EJB和jboss服务器是全新的
