javax.ejb.CreateException: Could not create stateless EJB
提问by user1182637
I'm using netbean 6.7.1 Glassfish v2.1 ... I'm trying to create message driven bean.
我正在使用 netbean 6.7.1 Glassfish v2.1 ...我正在尝试创建消息驱动 bean。
App A (using session bean, create map message) --> App B (message driven bean located here).
App A（使用会话 bean，创建地图消息）--> App B（位于此处的消息驱动 bean）。
@Stateless
public class AManagerBean implements AManagerRemote {
....
}
@Remote
public interface AManagerRemote {
...
}
In the main class of A,
在A的主类中，
@EJB
public static AManagerRemote AManager;
AManager.requestFineAmt(memberID);
In the requestFineAmt method, it consists of all those queue connection stuff.
在 requestFineAmt 方法中，它包含所有这些队列连接的东西。
When i try to run it. I received errors that state that stateless EJB could not be created. why???
当我尝试运行它时。我收到错误，指出无法创建无状态 EJB。为什么？？？

Make sure your EJB class and all the classes used there implements the Serializableinterface.
确保您的 EJB 类和那里使用的所有类都实现了该Serializable接口。
