Acknowledging messages using Spring JMS

Hello,
I would like to manually acknowledge each message I receive from the Solace queue using the JMS protocol. However with the configuration I have below, I am seeing that the messages are actually not being removed even after I explicitly call “message.acknowledge()” on the message.

@Bean()
    public DefaultJmsListenerContainerFactory connectionFactory(SolConnectionFactory solConnectionFactory, SolaceErrorHandler errorHandler) {
        DefaultJmsListenerContainerFactory factory = new DefaultJmsListenerContainerFactory();
        factory.setConnectionFactory(solConnectionFactory);
        factory.setErrorHandler(errorHandler);
        factory.setSessionAcknowledgeMode(Session.CLIENT_ACKNOWLEDGE);
        return factory;
    }

I couldn’t really find much documentation on manually ack-ing each message in the application. Should I be changing something here?

Thanks in advance

Hi @asx19 ,
Are you using the @JmsListener annotation on the receiving method?
If yes, can you try adding a name of “jmsListenerContainerFactory” to your DefaultJmsListenerContainerFactory bean and seeing if that works for you?

	@Bean(name = "jmsListenerContainerFactory")
	public DefaultJmsListenerContainerFactory connectionFactory(SolConnectionFactory solConnectionFactory) {
		DefaultJmsListenerContainerFactory factory = new DefaultJmsListenerContainerFactory();
		factory.setConnectionFactory(solConnectionFactory);
		factory.setErrorHandler(errorHandler);
		factory.setSessionAcknowledgeMode(Session.CLIENT_ACKNOWLEDGE);
		return factory;
	}

Once you get it working another thing to look into is whether you want to use the JMS default Session.CLIENT_ACKNOWLEDGE or if you want to use SupportedProperty.SOL_CLIENT_ACKNOWLEDGE

Hope that helps!

Hi @marc,
Thanks-- using SupportedProperty.SOL_CLIENT_ACKNOWLEDGE indeed solved the problem.
