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
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.
