Hi
The method is definitely returned in CXF 2.7.7, I've just added a
test confirming that. A lot of fixes went into the client-side 2.0
code, some of it is still on the trunk only as they deal more with
various very edgy TCK issues, I'm not sure yet if they should make
to CXF 2.7.8 or not, but a method getter works in 2.7.7
Re the actual exception, I guess this is because we don't have
DELETE with body supported yet

Hi Sergey.
First of all, excuse me by the duplicate message.
I have just written a Filter like this:
public class PostToDeleteWithBodyFilter implements
ClientRequestFilter {
public final static StringEXTRA_PATH= "/mutatePOSTtoDELETE";
@Override
public void filter(ClientRequestContext requestContext) throws
IOException {
String method = requestContext.getMethod();
String path = requestContext.getUri().__getPath();
if (path != null && path.endsWith(EXTRA_PATH)) {
// remove EXTRA_PATH
requestContext.setUri(URI.__create(path.substring(0, path.length() -
EXTRA_PATH.length())));
// transform POST into DELETE
requestContext.setMethod("__DELETE");
}
}
}
I have some issues again. The method var is null. And the most
important, an exception is thrown when I use this filter:

Hi
Can you register an instance of JAX-RS 2.0
ClientRequestFilter (as a
provider) and set your method & request URI if needed there ?
That should make it simpler for you.
Re using a custom CXF interceptor, it really should have the
properties which you check already set on the message passed to
handleMessage(), that message is an out message, so you
should have
"message == message.getExchange().____getOutMessage()" hold
true.

I have written something like this:

if (method != null && method.equals("POST") && path
!= null &&
path.endsWith(EXTRA_PATH)) {
// TODO remove EXTRA_PATH
// TODO transform POST into DELETE
}
}
}
I have a few doubts:
- I don't know how to modify the path and the
method of the
request. I
have tried modifying the content of the

- Why do I need to look for exchange, out message
to see
current path
and method? It should be in the message, but the
values are
null.

Probably not at the moment,
I've opened

Please watch it.
In meantime, may be it is possible to 'tunnel' it,
example,
use POST but
set some header with the real/intended HTTP verb
such as
DELETE, the target
server would need to replace POST with DELETE, the
easy way
is to say
create Servlet filter which will use HTTPServletRequest
wrapper to return
DELETE, some work is needed there but no changes to the
server code itself
will be required.
Otherwise - try snapshots once CXF-5337 gets resolved

This is the code based on the advice from
HttpClient
forums.
I guess we should check if CXF Async
Conduit can be
updated respectively
By the way, I'm assuming you have to do
DELETE with
a body because you
have some existing/legacy service expecting
it this
way ? Now and then
users ask about it, and I don't mind to get the
Async HTTP conduit
updated
a bit anyway, but if you have say a CXF server
listening, then I'm sure
there could be an easier way :-)

I
mean the Async HTTP client is being used.
However my DELETE request has

my Resource class is JaxB
annotated:
@Path("/server/path")
@DELETE
@Consumes(MediaType.****____APPLICATION_JSON)

I have a create method working with de same

I'm using Jackson as JSON serializer, but I
guess it has no relation

These log lines show that the DELETE
