cf http://support.cloudfoundry.com/entr...ng-application
This means adding the cloud: namespace declaration, and define the cloud:rabbit-connection-factory

Hi chanezon

it's not work.


is it working for you?


i have add the following to pom.xml

Basically i have followed the all the steps in

http://support.cloudfoundry.com/entr...ng-application

but it's not working too.


I do have question?

1. why it's different to : Database connection factory : I used mysql database resources it's work fine NOT need any [cloudfoundry-runtime jar runtime ] i think rabbit also should NOT used the
cloudfoundry-runtime , if it's need then, if we wont to run the application non - cloud env then it's has to change [connection factory ]

As fare as i understand cloud-foundry should proved proxy type of thing to rap around the underline resources

Is the RabbitMQ service provisioned? Is it definitely bound to your application?

As to your secondary question, you should no longer need the cloud namespace if you're happy to have your connection factory reconfigured. The org.springframework.amqp.rabbit.connection.Connect ionFactory class is automatically rewired to use the bound RabbitMQ service. However, this reconfiguration does not happen if you use <cloud:...> anywhere in your application context configuration.

Hope that helps,

Peter
