Supplying
...
a

Configuration
...
file
...
to
...
CXF
...
CXF
...
can
...
discover
...
XML
...
configuration
...
files
...
which
...
you
...
have
...
written.
...
For
...
both
...
web
...
service
...
clients
...
and
...
servers,
...
the
...
default
...
location
...
that
...
CXF
...
will
...
look
...
for
...
a
...
configuration
...
for
...
is
...
"/cxf.xml"
...
on
...
the
...
class
...
path.
...
For
...
example,
...
when
...
running
...
your
...
application
...
in
...
a
...
servlet
...
container,
...
this
...
file
...
is
...
expected
...
to
...
be
...
located
...
in
...
a /WEB-INF/classes
...
folder of your web application.
If you wish to override this location, you can specify a command line property: -Dcxf.config.file=some_other_config.xml.
...
This
...
custom
...
configuration
...
file
...
is
...
also
...
expected
...
to
...
be
...
on
...
the
...
class
...
path.
...
To
...
use
...
a
...
url
...
as
...
the
...
configuration
...
location,
...
specify
...
as
...
follows:
...
-Dcxf.config.file.url=config_file_url.
...
A
...
CXF
...
configuration
...
file
...
is
...
really
...
a
...
...
configuration
...
file,
...
so
...
all
...
configuration
...
files
...
will
...
start
...
with
...
the
...
following:
| Code Block | ||||

more

The

is

the

Typically, the cxf.xml
...
file
...
in
...
the
...
classpath
...
of
...
the
...
web
...
service
...
is
...
intended

primarily

for

configuration

of

the

CXF

the

object
...
used

for

the

creation
...
of

all

services

and

endpoints.
...
Endpoint

configuration
...
is
...
primarily
...
done
...
either
...
via
...
a
...
WEB-INF/cxf-servlet.xml
...
file
...
or
...
a

Spring
...
application

context
...
file
...
designated
...
by
...
the
...
web
...
application
...
deployment
...
descriptor
...
(web.xml
...
file).
...
The cxf-servlet.xml
...
file
...
is
...
somewhat
...
slower
...
because
...
it
...
loads
...
all
...
possible
...
CXF
...
modules
...
for
...
an
...
endpoint;
...
the
...
Spring
...
application
...
context
...
method
...
is
...
faster
...
because
...
it
...
allows
...
you
...
to
...
specify
...
which
...
CXF
...
modules
...
are
...
needed.
...
For
...
an
...
example
...
configuration
...
via
...
a
...
cxf-servlet.xml
...
file,
...
our
...
...
tests have a cxf-servlet.xml file which is explicitly referenced in the init-param element in the web.xml deployment descriptor. (Note it is not necessary to use the init-param element if you use the file name "cxf-servlet.xml";
...
this
...
is
...
the
...
default
...
name
...
that
...
CXF
...
uses
...
to
...
look
...
for
...
such
...
a
...
file.)
...
For
...
an
...
example
...
of
...
using
...
a
...
Spring
...
application
...
context
...
file
...
for
...
endpoint
...
configuration,
...
refer
...
to
...
our
...
...
...
...
...
sample.
...
You
...
can
...
see how the web.xml deployment descriptor explicitly references the beans.xml application context file via a context-param element (and ContextLoaderListener object); also that the application context file manually imports the three cxf modules that it needs.
What can I configure and how do I do it?
If you want to change CXF's default behaviour, enable specific functionality or fine tune a component's behaviour, you can in most cases do so without writing a single line of code, simply by supplying a Spring configuration file.
In some cases it also possible to achieve the same end by extending your wsdl contract: you can add CXF specific extension elements to the wsdl:port element and in that way fine tune the behaviour of the specified transport. Or you can use WS-Policy to express the fact that your application uses WS-Addressing, for example.
Using Spring configuration files however is the most versatile way to achieve a specific goal: you can use it to
- Enable functionality via simple constructs called features.
- Set properties of runtime components by referring to these runtime components using either plain Spring bean elements, or, more conveniently, using CXF custom beans elements.
- Modify the actual composition of the runtime (change the way the runtime is wired up).
The following examples show the what the Spring configuration would look like if you wanted to enable the logging of inbound and outbound messages and faults.

In

you

specify

that

the

CXF

is

implemented

class

you

you

to

contribute
