Interface RedeliveryHandler

All Known Implementing Classes:

AbstractRedeliveryHandler, CountingRedeliveryHandler, JmsXRedeliveryHandler

public interface RedeliveryHandler

RedeliveryHandler is used to control how redelivered messages are processed by a connector. Typically, a messsage will be re-tried once or twice before throwing an exception. Then the exception strategy on the connector can be used to forward the message to a JMS queue or log the failure.

Method Summary

void	handleRedelivery(Message message, ImmutableEndpoint endpoint, FlowConstruct flow) Process the redelivered message.
void	setConnector(JmsConnector connector) The connector associated with this handler is set before handleRedelivery() is called

Method Detail

setConnector

void setConnector(JmsConnector connector)

The connector associated with this handler is set before handleRedelivery() is called

Parameters:

connector - the connector associated with this handler

handleRedelivery

void handleRedelivery(Message message,
                      ImmutableEndpoint endpoint,
                      FlowConstruct flow)
                      throws JMSException,
                             MuleException

Process the redelivered message. If the JMS receiver should process the message, it should be returned. Otherwise the connector should throw a MessageRedeliveredException to indicate that the message should be handled by the connector's exception handler.

Parameters:

message - the redelivered message

endpoint - from which the message was received

flow/service - in which the exception occured, this is used to obtain the appropriate exception handler

Throws:

JMSException - if properties cannot be read from the JMSMessage

MessageRedeliveredException - should be thrown if the message should be handled by the connection exception handler

MuleException - if there is a problem reading or proessing the message
