Yep, the ESB allows you to plug in logic between your inflow and outflow(s) e.g. split the message and route each of them to multiple outbound routers (outflows), transforming the message payload differently for each destination etc. Basically, do whatever it takes to make a message produced at A consumable at B, without having to modify A or B (i.e. develop point-to-point solutions). JCA can handle the transport end of this only, right? View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4038063#...
