我正在使用 netbean 6.7.1 Glassfish v2.1 ...我正在尝试创建消息驱动的 bean。

应用程序 A(使用会话 bean,创建映射消息)--> 应用程序 B(位于此处的消息驱动 bean)。

@Stateless
public class AManagerBean implements AManagerRemote {
....
}

@Remote
public interface AManagerRemote {
...
}

在A的主类中,

@EJB
public static AManagerRemote AManager;
AManager.requestFineAmt(memberID);

在 requestFineAmt 方法中,它包含所有这些队列连接的东西。

当我尝试运行它时。我收到指出无法创建无状态 EJB 的错误。为什么???

确保您的 EJB 类和其中使用的所有类都实现了该Serializable接口。
