Content-Based Router - questions

[vsp <v-...@mail.ru>]

Whether I can construct such route by means of the Content-Based Router
(CBR)?:

                                                                   <-> SE 1
(changing a message and return it to CBR)
                 Quartz -> EIP-Pipeline <-> IP-CBR  <-> SE 2 (changing a
message and return it to CBR)
                                                             \     <-> SE 3
(changing a message and return it to CBR)
                                                              \> SE 4 (final
of the route)

Which type of messages Content-Based Router sends? (InOnly or InOut)

And another question: how to make transform from InOut message to InOnly
message?

L.S.,


I don't think the content-based router can be used to re-route the 
response message, e.g. the response message coming from SE 1 won't be 
evaluated by the router.  You can use a static routing slip to reroute 
the response coming out of the CBR back in there several times to get 
the desired behavior.  Off course, if you always have to call on the 4 
SE's, you're better off just using the static routing slip without the 
CBR.  The Content-Based Router can send both types of message exchanges, 
InOnly and InOut.

AFAIK, there is no built-in solution to transform from InOut to InOnly. 
  You probably need to develop a service that is able to receive the 
InOut and answer it, while forwarding the in message to the next service.

P.S. Your routing use case might be a good match for Apache Camel (rule 
based routing and mediation engine), but I have no idea how to combine 
it with ServiceMix.
