  Hi Rishi,

I am a SAP XI consultant in Johannesburg and also play around with 
RabbitMQ when I get a chance.

Your question is very interesting, and one that I have wondered about 
before. Obviously the long term approach would be to develop a sender / 
receiver Java adapter for SAP XI / PI to handle the AMQP communication, 
but the disadvantage here is that adapter development can be tricky and 
has a relatively steep learning curve. But if you have the skills I say 
go for it.

I have not been following the current "adapters" for RabbitMQ, but I 
would imagine that putting some sort of RESTful / HTTP interface using 
something like MochiWeb would be pretty simple to talk to from a SAP XI 
HTTP adapter. I know this is not perfect but an option nevertheless.

Sending messages from RabbitMQ to SAP XI would be very easy from a proof 
of concept point of view. As you already know you would simple build up 
the URL to post the XML message to using the correct channel, sender 
service, sender interface etc in the


Writing an "adapter" for RabbitMQ that takes messages off a queue and 
sends them to a configurable URL like the one above should not be too hard.

A question for you: What format would the messages be in on the RabbitMQ 
queue? Already in "SAP XI XML" format?

The bottomline is their are many ways one could do this, if you had to 
ask me my choice I would choose between the following 2:

1. Create a custom Java adapter for both the sender AMQP and receiver 
AMQP adapter

2. On the next option I speak from experience in doing it and it works 
         - Create an RFC Server in C / C++. This could be called from 
SAP XI and pass the messages to it, from there you would simple use some 
RabbitMQ API to send the messages to RabbitMQ
         - For sending messages to SAP I would just post the message 
straight to SAP XI using something like the URL above. You could easily 
write such a HTTP client in Erlang (or Python etc) and "plug it in as an 
adapter" to RabbitMQ.

Let me brainstorm it a little more, but feel free to email me and we can 
discuss this more to get the best answer.
