I'm just one of those users who knows how things should be done :-) without
doing much myself :-)
You guys are good!
That's a compliment for the CXF team.
Cheers, Sergey

Wow. You guys are good! Thanks for educating me! That's a far better
solution than anything I had proposed. =)

One clarification :
I don't think there's a way to detect whether or not MTOM should be
used on the client side of things.
Given the assertion below (which is advertised by a service in its WSDL)
the WS-Policy aware client can inspect the service's policy
assertions and find out that it may use MTOM if it wishes
to...Furthermore, the policy-aware client (NET is most likely able to do
it) can decide through the intersection if it wants to talk to this
service depending on whether it supports MTOM or not

Hi
This is exactly what an MTOM policy assertion is for, please see
Optional assertions in the policy primer at
http://www.w3.org/TR/2007/WD-ws-policy-primer-20070330/
and the MTOM assertion spec :
http://schemas.xmlsoap.org/ws/2004/09/policy/optimizedmimeserialization/
The service which wishes to support both MTOM-aware and MTOM-unaware
clients will just do :
in <wsdl:service> or wsdl:service/wsdl:port :
<Policy>
<mtom:optimizedMimeSerialization optional="true"/>
</Policy>
The server then determines whether to use the MIME processing or not
depending on the presence of the a related mime header
Cheers, Sergey

How would this work from the Client side? Would it just be always or
never
then? I don't think there's a way to detect whether or not MTOM
should be
used on the client side of things.
BTW - I fixed your bugs in SVN. We haven't published a new snapshot
quite
yet though. That should happen later today I would think.

Note: There are three server MTOM modes: "optional", "always", and
"never".
Always means that the service "always" requires MTOM messages from
the
client and will "always" return response messages using MTOM.
Never means that MTOM will never be used-and the service will reject
MTOM requests.
Optional (the default) means the service will respond in kind to the
type of message sent by the client. So if the client sends an MTOM
request, it will respond with an MTOM response.

I don't know if this goes against any specs or is too difficult to
implement, but it seems to me that this would be a neat feature:
MTOM By Request:
- If a request comes in using MTOM, then respond using MTOM.
- If a request comes in using text/xml, then respond with test/xml.
This way, a single deployed service can support both MTOM-enabled
and
non-MTOM-enabled clients.
Any thoughts?
