javax.ejb Interface MessageDrivenBean

所有父接口:: EnterpriseBean, Serializable

public interface MessageDrivenBean
extends EnterpriseBean

The MessageDrivenBean interface is implemented by every message-driven enterprise Bean class. The container uses the MessageDrivenBean methods to notify the enterprise Bean instances of the instance's life cycle events.

方法摘要
`void`	`ejbRemove()` A container invokes this method before it ends the life of the message-driven object.
`void`	`setMessageDrivenContext(MessageDrivenContext ctx)` Set the associated message-driven context.

方法详细信息

setMessageDrivenContext

void setMessageDrivenContext(MessageDrivenContext ctx)
                             throws EJBException

Set the associated message-driven context. The container calls this method after the instance creation.

The enterprise Bean instance should store the reference to the context object in an instance variable.

This method is called with no transaction context.

参数:: ctx - A MessageDrivenContext interface for the instance.
抛出异常:: EJBException - Thrown by the method to indicate a failure caused by a system-level error.

ejbRemove

void ejbRemove()
               throws EJBException

A container invokes this method before it ends the life of the message-driven object. This happens when a container decides to terminate the message-driven object.
