[rabbitmq-discuss] To declare a MQ listener at java application startup

[Jon Brisbin]

Have you looked at "basicConsume" on the Channel object?

http://www.rabbitmq.com/releases/rabbitmq-java-client/v1.8.0/rabbitmq-java-client-javadoc-1.8.0/com/rabbitmq/client/Channel.html

Or do you mean: "more specifically, how do you manage multi-threading issues when managing consumers"?

The latter is a black hole of a topic. :)

The API guide, though Spartan, is a good starting point:

You could set up a global naming resource, or you could scope it to your web application by putting it in META-INF/context.xml: http://tomcat.apache.org/tomcat-6.0-doc/jndi-resources-howto.html
