Subject Re: Using Camel in large project (300 Applications to integrate)
Date Thu, 17 Sep 2015 06:57:53 GMT
Hi Nick

The reason we typically have 2 war files pr integration is to separate the
responsibilities between provider and consumer systems. 
An example :
Recieve xml files in a folder -> transform them -> send the message to 1 or
more consumer systems.

Camel context 1 (in war file1) -> reads the xml and transforms it and puts
in on a jms queue -> myqueue.
Camel context 2 (in war file2) -> dequeues from myqueue and sends payload to
consumer systems.

The benefit is that you can deploy/scale them separately even on different
nodes, and there is no coupling between provider and consumer systems (via
jms queue) so systems can come and go without affecting each other.
