Subject Re: [jira] [Commented] (CXF-3768) HTTP response code 202 is not set for WS-Addressing partial responses
Date Mon, 29 Aug 2011 20:43:52 GMT
Hi Dan,
There is a minor problem in fixing the create sequence response case
for decoupled clients that I mentioned.

If we make this change so that the WS-RM provider (or the server) for
a decoupled client returns an HTTP 202 with no content for the
CreateSequence call, the WS-RM client must also be modified to not
expect any response for this call. Unfortunately, it currently expects
an empty SOAP body response because the call is not considered oneway
from the application point of view but it is executed as oneway in the
transport layer as the real create sequence response comes back into
the decoupled endpoint.

So the Client, that is HTTPConduit's response handling code also needs
to be changed to accept HTTP 202 in this case. Should we need to
provide a configuration option to make the server fall back to the old
http 200 behavior so that the old CXF WS-RM clients don't get problems
at executing their create sequence calls or should we just down port
this client side fix to 2.3. et al and document it as an
incompatibility issue for the older CXF with the new ones?

I think we can just fix this behavior and align it with the standard
without providing the fallback behavior option because the problem
will happen only when those very old clients are talking to the
patched 2.4 and 2.5 servers. And those old clients will certainly have
ineroperability issues with other servers as well. How do you think?

Thanks.
regards, aki

>>> Well, part of the problem is that CXF is returning a non-empty partial response
when it should be returning an empty one.    I started looking into this briefly on Friday
and noticed that when the incoming request has a reply to to a decoupled dest, we're sending
back a 200 with a message with an envelope with an empty body.   The 200 is correct there.
  Instead, it SHOULD be a 202 with an empty response.

>>>> When asyncronous processing is requested by specifying an endpoint reference
in the request's ReplyTo WSA header, an immediate acknowledgement should be sent with HTTP
code 202.  Older CXF versions (e.g. 2.2.11) implemented this requirement in the method {{org.apache.cxf.transport.http.AbstractHTTPDestination#markPartialResponse}},
but the newer ones (2.4.1, 2.4.2) do not set the HTTP response code explicitely, therefore
acknowledgements are delivered with code 200.
