CXF
...
Component
...
When using CXF as a consumer, the CXF Bean Component allows you to factor out how message payloads are received from their processing as a RESTful or SOAP web service. This has the potential of using a multitude of transports to consume web services. The bean component's configuration is also simpler and provides the fastest method to implement web services using Camel and CXF.
...
When using CXF in streaming modes (see DataFormat option), then also read about Stream caching.
The cxf: component provides integration with Apache CXF for connecting to JAX-WS services hosted in CXF.
Maven users will need to add the following dependency to their pom.xml
for this component:

Where cxfEndpoint represents a bean ID that references a bean in the Spring bean registry. With this URI format, most of the endpoint details are specified in the bean definition.

How to enable CXF's

Since

(but

the

The

following

is

an

example.

...
Description

of

relayHeaders
...
option
...
There
...
are
...
in-band
...
and
...
out-of-band
...
on-the-wire
...
headers
...
from
...
the
...
perspective
...
of
...
a
...
JAXWS
...
WSDL-first
...
developer.
...
The
...
in-band
...
headers
...
are
...
headers
...
that
...
are
...
explicitly
...
defined
...
as
...
part
...
of
...
the
...
WSDL
...
binding
...
contract
...
for
...
an
...
endpoint
...
such
...
as
...
SOAP
...
headers.
...
The
...
out-of-band
...
headers
...
are
...
headers
...
that
...
are
...
serialized
...
over
...
the
...
wire,
...
but
...
are
...
not
...
explicitly
...
part
...
of
...
the
...
WSDL
...
binding
...
contract.
...
Headers
...
relaying/filtering
...
is
...
bi-directional.
...
When
...
a
...
route
...
has
...
a
...
CXF
...
endpoint
...
and
...
the
...
developer
...
needs
...
to
...
have
...
on-the-wire
...
headers,
...
such
...
as
...
SOAP
...
headers,
...
be
...
relayed
...
along
...
the
...
route
...
to
...
be
...
consumed
...
say
...
by
...
another
...
JAXWS
...
endpoint,
...
then
...
relayHeaders
...
should
...
be
...
set
...
to
...
true
...
,
...
which
...
is
...
the
...
default

value.
...

mode
...
The

relayHeaders=true
...
express
...
an
...
intent
...
to

relay
...
the
...
headers.
...
The
...
actual
...
decision
...
on
...
whether
...
a
...
given
...
header
...
is
...
relayed
...
is
...
delegated
...
to
...
a
...
pluggable
...
instance
...
that
...
implements
...
the
...
MessageHeadersRelay
...
interface.
...
A
...
concrete
...
implementation
...
of
...
MessageHeadersRelay
...
will
...
be
...
consulted
...
to
...
decide
...
if
...
a
...
header
...
needs
...
to
...
be
...
relayed
...
or
...
not.
...
There
...
is
...
already
...
an
...
implementation
...
of
...
SoapMessageHeadersRelay
...
which
...
binds
...
itself
...
to
...
well-known
...
SOAP
...
name
...
spaces.
...
Currently
...
only
...
out-of-band
...
headers
...
are
...
filtered,
...
and
...
in-band
...
headers
...
will
...
always
...
be
...
relayed
...
when
...
relayHeaders=true
...
.
...
If
...
there
...
is
...
a
...
header
...
on
...
the
...
wire,
...
whose
...
name
...
space
...
is
...
unknown
...
to
...
the
...
runtime,
...
then
...
a
...
fall
...
back
...
DefaultMessageHeadersRelay
...
will
...
be
...
used,
...
which
...
simply
...
allows
...
all
...
headers
...
to
...
be
...
relayed.
...
The
...
relayHeaders=false
...
setting
...
asserts
...
that
...
all
...
headers
...
in-band
...
and
...
out-of-band
...
will
...
be
...
dropped.
...
You
...
can
...
plugin
...
your
...
own
...
MessageHeadersRelay
...
implementations
...
overriding
...
or
...
adding
...
additional
...
ones
...
to
...
the
...
list
...
of
...
relays.
...
In
...
order
...
to
...
override
...
a
...
preloaded
...
relay
...
instance
...
just
...
make
...
sure
...
that
...
your
...
MessageHeadersRelay
...
implementation
...
services
...
the
...
same
...
name
...
spaces
...
as
...
the
...
one
...
you
...
looking
...
to
...
override.
...
Also
...
note,
...
that
...
the
...
overriding
...
relay
...
has
...
to
...
service
...
all
...
of
...
the
...
name
...
spaces
...
as
...
the
...
one
...
you
...
looking

to

override,
...
or
...
else
...
a

runtime
...
exception
...
on

route
...
start

up
...
will

be

thrown

this

would

introduce
...
an
...
ambiguity
...
in

name

spaces
...
to

Take

a

look

the

POJO
...
mode
...
POJO
means that the data format is a "list of Java objects" when the Camel-cxf endpoint produces or consumes Camel exchanges. Even though Camel expose message body as POJOs in this mode, Camel-cxf still provides access to read and write SOAP headers. However, since CXF interceptors remove in-band SOAP headers from Header list after they have been processed, only out-of-band SOAP headers are available to Camel-cxf in POJO mode.
The following example illustrate how to get/set SOAP headers. Suppose we have a route that forwards from one Camel-cxf endpoint to another. That is, SOAP Client -> Camel -> CXF service. We can attach two processors to obtain/insert SOAP headers at (1) before request goes out to the CXF service and (2) before response comes back to the SOAP Client. Processor (1) and (2) in this example are InsertRequestOutHeaderProcessor and InsertResponseOutHeaderProcessor. Our route looks like this:
...
SOAP
...
headers
...
are
...
propagated
...
to
...
and
...
from
...
Camel
...
Message
...
headers.
...
The
...
Camel
...
message
...
header
...
name
...
is
...
"org.apache.cxf.headers.Header.list"
...
which
...
is
...
a
...
constant
...
defined
...
in
...
CXF
...
(org.apache.cxf.headers.Header.HEADER_LIST).
...
The
...
header
...
value
...
is
...
a
...
List
...
of
...
CXF
...
SoapHeader
...
objects (org.apache.cxf.binding.soap.SoapHeader). The following snippet is the InsertResponseOutHeaderProcessor (that insert a new SOAP header in the response message). The way to access SOAP headers in both InsertResponseOutHeaderProcessor and InsertRequestOutHeaderProcessor are actually the same. The only difference between the two processors is setting the direction of the inserted SOAP header.
How to get and set SOAP headers in PAYLOAD mode
We've already shown how to access SOAP message (CxfPayload object) in PAYLOAD mode (See "How to deal with the message for a camel-cxf endpoint in PAYLOAD data format").
Once you obtain a CxfPayload object, you can invoke the CxfPayload.getHeaders() method that returns a List of DOM Elements (SOAP headers).
...
SOAP headers are not available in MESSAGE mode
SOAP headers are not available in MESSAGE mode as SOAP processing is skipped.
How to throw a SOAP Fault from Camel
If you are using a camel-cxf
endpoint to consume the SOAP request, you may need to throw the SOAP Fault from the camel context.
Basically, you can use the throwFault
DSL to do that; it works for POJO
, PAYLOAD
and MESSAGE
data format.
You can define the soap fault like this
...
Then
...
throw
...
it
...
as

your

CXF
...
endpoint
...
is

in

format,
...
you
...
could

set

the

the

message

header.

...
Same

format.

You

can

set
...
the

SOAPFault
...
on
...
the

out

body
...
and

also

Attachment Support
POJO Mode: Both SOAP with Attachment and MTOM are supported (see example in Payload Mode for enabling MTOM). However, SOAP with Attachment is not tested. Since attachments are marshalled and unmarshalled into POJOs, users typically do not need to deal with the attachment themself. Attachments are propagated to Camel message's attachments if the MTOM is not enabled, since 2.12.3. So, it is possible to retreive attachments by Camel Message API
...
.
Payload Mode: MTOM is supported since 2.1. Attachments can be retrieved by Camel Message APIs mentioned above. SOAP with Attachment (SwA) is supported and attachments can be retrieved since 2.5. SwA is the default (same as setting the CXF endpoint property "mtom-enabled" to false).
To enable MTOM, set the CXF endpoint property "mtom-enabled" to true. (I believe you can only do it with Spring.)
...
You
...
can
...
produce
...
a
...
Camel
...
message
...
with
...
attachment
...
to
...
send
...
to
...
a
...
CXF
...
endpoint
...
in
...
Payload
...
mode.
...
...
You
...
can
...
also
...
consume
...
a
...
Camel
...
message
...
received
...
from
...
a
...
CXF
...
endpoint
...
in
...
Payload
...
mode.
...
...
Message
...
Mode:
...
Attachments
...
are
...
not
...
supported
...
as
...
it
...
does
...
not
...
process
...
the
...
message
...
at all.
CXF_MESSAGE Mode: MTOM is supported, and Attachments can be retrieved by Camel Message APIs mentioned above. Note that when receiving a multipart (i.e. MTOM) message the default SOAPMessage to String converter will provide the complete multipart payload on the body. If you require just the SOAP XML as a String, you can set the message body with message.getSOAPPart(), and Camel convert can do the rest of work for you.
Streaming Support in PAYLOAD mode
In 2.8.2,
...
the
...
camel-cxf
...
component
...
now
...
supports
...
streaming
...
of
...
incoming
...
messages
...
when
...
using
...
PAYLOAD
...
mode.
...
Previously,
...
the
...
incoming
...
messages
...
would
...
have
...
been
...
completely
...
DOM
...
parsed.
...
For
...
large
...
messages,
...
this
...
is
...
time
...
consuming
...
and
...
uses
...
a
...
significant
...
amount
...
of
...
memory.
...
Starting
...
in
...
2.8.2,
...
the
...
incoming
...
messages
...
can
...
remain
...
as
...
a
...
javax.xml.transform.Source
...
while
...
being
...
routed
...
and,
...
if
...
nothing
...
modifies
...
the
...
payload,
...
can
...
then
...
be
...
directly
...
streamed
...
out
...
to
...
the
...
target
...
destination.
...
For
...
common
...
"simple
...
proxy"
...
use
...
cases
...
(example:
...
from("cxf:...").to("cxf:...")),
...
this
...
can
...
provide
...
very
...
significant
...
performance
...
increases
...
as
...
well
...
as
...
significantly
...
lowered
...
memory
...
requirements.
...
However,
...
there
...
are
...
cases
...
where
...
streaming
...
may
...
not
...
be
...
appropriate
...
or
...
desired.
...
Due
...
to
...
the
...
streaming
...
nature,
...
invalid
...
incoming
...
XML
...
may
...
not
...
be
...
caught
...
until
...
later
...
in
...
the
...
processing
...
chain.
...
Also,
...
certain
...
actions
...
may
...
require
...
the
...
message
...
to
...
be
...
DOM
...
parsed
...
anyway
...
(like
...
WS-Security
...
or
...
message
...
tracing
...
and
...
such)
...
in
...
which
...
case
...
the
...
advantages
...
of
...
the
...
streaming
...
is
...
limited.
...
At
...
this
...
point,
...
there
...
are
...
two
...
ways
...
to
...
control
...
the
...
streaming:
...
- Endpoint
...
- property:
...
- you
...
- can
...
- add
...
- "allowStreaming=false"
...
- as
...
- an
...
- endpoint
...
- property
...
- to
...
- turn
...
- the
...
- streaming
...
- on/off.
...
- Component
...
- property:
...
- the
...
- CxfComponent
...
- object
...
- also
...
- has
...
- an
...
- allowStreaming
...
- property
...
- that
...
- can
...
- set
...
- the
...
- default
...
- for
...
- endpoints
...
- created
...
- from
...
- that
...
- component.
...
Global
...
system
...
property:
...
you can add a system property of "org.apache.camel.component.cxf.streaming" to "false" to turn if off. That sets the global default, but setting the endpoint property above will override this value for that endpoint.
Using the generic CXF Dispatch mode
From 2.8.0, the camel-cxf component supports the generic CXF dispatch mode that can transport messages of arbitrary structures (i.e., not bound to a specific XML schema). To use this mode, you simply omit specifying the wsdlURL and serviceClass attributes of the CXF endpoint.
...
It is noted that the default CXF dispatch client does not send a specific SOAPAction header. Therefore, when the target service requires a specific SOAPAction value, it is supplied in the Camel header using the key SOAPAction (case-insensitive).
