[rabbitmq-discuss] Silverlight application with RabbitMQ

Fri May 7 07:16:52 BST 2010

Jens Aernouts,

As you found out Kaazing supports AMQP 0-9-1 protocol. It works great
against QPid 0.6 (which supports AMQP 0-9-1). RabbitMQ support for
AMQP 0-9-1 in the development branch is not very stable and is
difficult to get it to run. There is no news from RabbitMQ about when
it will be released.

If you have to use RabbitMQ only, you can try Kaazing's StompClient
implementation to work against RabbitMQ with STOMP adapter. We have
tested Kaazing's StompClient against RabbitMQ with stomp adapter
successfully. StompClient provides with capability to send binary data
to server as a ByteBuffer. You don't have to worry about the content-
length header referred above - it is all taken care for you in the
StompClient library. Kaazin's StompClient library is available to you
in Javascript, Silverlight, .NET, Flex, Java or JavaFX.

Best Regards,
Sidda
