邮件不会自动移至死信通道（DLC）-Broker-WSO2 EI

Question

Im using WSO2 EI 6.1.1 with Message Broker, and trying to create message queue with message store and message process with an endpoint.

When I shutdown my endpoint, the message processor is deactivated and the messages stay in the queue and they are not moved to DLC.

What should I do to make it work ?

Thanks,

This is the expected behavior with message processor / message store :

• A scheduled message processor will try to send the message until the delivery is successfull (and offers you a way to implement guaranteed delivery pattern)
• A sampling message processor will send the message in a non reliable way (it can be lost)

If you want to manage a JMS transaction and have the message to go in DLQ, use a jms inbound endpoint or jms proxy and set required parameters (transport.jms.SessionTransacted, transport.jms.SessionAcknowledgement : have a look to wso2 documentation https://docs.wso2.com/display/EI611/JMS+Transactions )

Message store / processor is used to implements Dead letter channel EIP : the jms store host the dead message and you don't want it to be moved elsewhere
