Using exchange send b/w cxf bc and cxf se .
We have a SA having the below flow:
CXF BC -> CXF SE-> JMS BC
the message exchange between the cxf bc and cxf se is IN-Only.(configured
using wsdl in the BC).
Can this IN-Only exchange be accessed from within the cxf se pojo class so
that we can reuse it to send it to the JMS BC.(some processing need to be
done on the message received at the pojo side) or should we always create a
new exchange from the pojo for forwarding to another service.????
Basically i want to use only one exchange for all of my messages.

Hi,
In any case, reuse the message exchange is impossible IMHO. You have
to extract the message exchange(SU1 receiving from BC2) content and
set it to another new created message exchange.
Moreover, instead of trying to reuse this message exchnage, you should
set DONE status to the message exchange in your SU1 after receiving
from BC2 and send this message exchange with DONE status to BC2 to let
the NMR know one message exchange lifecycle is done.

Okies...Thanks
To make my case more clear,see the case below:
BC1(original message exchange)==>SU1<==>BC2==>SU2(SU1 forward reply got from
BC2 to SU2)
Inside the SU1,its not mere forwarding,
1) SU1 send the message got from the BC1(as In-Only) to another BC2 (as
In-Out).
2) Receive back the reply inside SU1 and then send that reply message to
SU2.Its here i was trying to reuse the original In-only exchange.
SU1 thus has 2 send process,first send to a BC (In-out) and then on
receiving the reply send to SU2(in-Only).(so cant avoid SU1)
Please let me know your comments.Should i drop the idea to reuse the in-only
exchange.??

Yeah.
And moreover, let's assume the flow is
bc endpoint su(which send original message exchange)===>
SU1==(forward)==> SU2
here SU1 receive the message exchange, and want to forward it to the
SU2. Here SU1 is a provider(like a server) when receive the message
exchange from bc endpoint su, but is a consumer(like a client) when
send the message exchange to SU2, it's different role.
If you only want SU1 just do some forward work(I mean not touch the
real message content), why not you send just the message exchange
directly from bc endpoint su to SU2?

so does that mean that if have a SA with multiple SU and we need to pass one
attachment.Then when passing the message from one SU to another we need to
extract content from the received message and then create a new exchange and
set this content and then forward it to the next SU.
In that case a exchange is valid only between two SU's and cannot be
forwarded further.is my understanding right sir??

Hi,
I think you miss my reply to your previous mail thread with title
"Reusing same message exchange for different message/service."
No, you do need create a new exchange for each message as the message
exchange has certain life cycle (something like status ACTIVE/DONE),
so you can't use one message exchange for all your messages. Also each
MessageExchange instance has unique exchangeId, it's really designed
to use as one "Message Exchange".
