[rabbitmq-discuss] Problems while trying interoperability

Thu Aug 16 12:33:31 BST 2007

Rob,

Anything to minimise Qpid / RabbitMQ deltas on how the spec is
implemented would be great - thanks.  We'll do the same if the case
arises.  And thanks very much for being on this group so we can work
with your team to ensure interop is real and not vapour.

Tanmay,

As Matthias pointed out, pending a patch of the type Rob mentions, you
can also do this as an interop workaround:

1) Qpid client -> RabbitMQ broker --- run RabbitMQ in "lax" mode (ie
we reduce our spec implementation surface for interop).
2) RabbitMQ client -> QPid server --- do not do the accessRequest and
use a hard-coded ticket# instead

For (1) lax mode is enabled by default so please *do* send us your logs.

Cheers

alexis
