Interface MessageDrivenBean

All Superinterfaces:: EnterpriseBean, Serializable

void setMessageDrivenContext(MessageDrivenContext ctx)
Set the associated message-driven context.

setMessageDrivenContext

public 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.

Parameters:: ctx - - A MessageDrivenContext interface for the instance.
Throws:: EJBException - - Thrown by the method to indicate a failure caused by a system-level error.

ejbRemove

public void ejbRemove()
               throws EJBException
