Hi,
I'm using CXF to create a jax-rs web service. Accessing the service from
a simple HTML form works correctly.
However when using curl to send a binary attachment, I get the following
server side exception

curl by default seems to issue a "Expect: 100-continue". The web service
call works if I disable "Expect: 100-continue" support. In this case
curl will post the request immediately. I have confirmed using some
other client application that if the client uses "Expect: 100-continue",
the web service does not function.
It seems that CXF jax-rs with netty as the HTTP(s) transport, does not
support "Expect: 100-continue" out of the box. Is there something I'm
missing in my configuration? Is it possible to enable "Expect:
100-continue" support?
Kind regards,
Martijn Brinkers
PS I'm using CXF 3.0.12
