Hello. Please forgive me if this is a basic question, but I have been hunting
through the Camel documentation and patterns and not found what I’m looking
for.
I have a JMS infrastructure which is passing messages between two systems. I
have created a simple camel route, something along the lines of:
from (jms:RequestSystemA).
inOut (jms:RequestSystemB?ReplyTo=ResponseSystemB).
to (jms:ResponseSystemA);
(The actual route contains some processing along the way, but I left this
out for the sake of simplification)
This is working for my basic cases. However, when a request is sent to
system B, it sometime simply returns a response and other times will send
back multiple messages to say that the request is being processed, and then
at a later time the final response is sent. This whole process can take up
to a two minutes to complete.
So what I would like is to create a route, something like:
Get message from system A and send it to system B.
Listen to a response from system B with a matching correlation ID.
if the response is a status update, send it to System A
But continue to listen for the next message (also possibly a status update)
If the message is the processing result, send that to system A
and end the job.
So maybe something like...
from ( jms:RequestSystemA ).
inOut ( jms:RequestSystemB?ReplyTo=ResponseSystemB ).
loop ().while( messageType = statusUpdate ).
to ( jms:ResponseSystemA ).
from ( jms:ResponseSystemB ).
end ().
to ( jms:ResponseSystemA );
Each of the status updates as well as the final response all come from
system B with the same correlation id.
Is something like this possible?
Thanks for any assistance.
