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:

the

JARS

...

text

file.

...

URI format

...

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.

...

Where someAddress specifies the CXF endpoint's

...

address.

With

Options

Name

Required

Description

wsdlURL

No

The location of the WSDL. It is obtained from endpoint address by default.

Example: file://local/wsdl/hello.wsdl

...

or

...

wsdl/hello.wsdl

...

serviceClass

Yes

The name of the SEI (Service Endpoint Interface) class. This class can have, but does not require, JSR181 annotations.
This option is only required by POJO mode. If the wsdlURL option is provided, serviceClass is not required for PAYLOAD and MESSAGE mode. When wsdlURL option is used without serviceClass, the serviceName and portName (endpointName for Spring configuration) options MUST be provided. It is possible to use # notation to reference a serviceClass object instance from the registry. E.g. serviceClass=#beanName. The serviceClass for a CXF producer (that is, the to endpoint) should be a Java interface.
Since 2.8, it is possible to omit both wsdlURL and serviceClass options for PAYLOAD and MESSAGE mode. When they are omitted, arbitrary XML elements can be put in CxfPayload's body in PAYLOAD mode to facilitate CXF Dispatch Mode.

Please be advised that the referenced object cannot be a Proxy (Spring AOP Proxy is OK) as it relies on Object.getClass().getName()

cxfEndpointConfigurer

No

New in Camel 2.11. This option could apply the implementation of org.apache.camel.component.cxf.CxfEndpointConfigurer which supports to configure the CXF endpoint in  programmatic way. Since Camel 2.15.0, user can configure the CXF server and client by implementing configure{Server|Client} method of CxfEndpointConfigurer.

username

No

New in Camel 2.12.3 This option is used to set the basic authentication information of username for the CXF client.

password

No

New in Camel 2.12.3 This option is used to set the basic authentication information of password for the CXF client.

continuationTimeout

No

New in Camel 2.14.0 This option is used to set the CXF continuation timeout which could be used in CxfConsumer by default when the CXF server is using Jetty or Servlet transport. (Before Camel 2.14.0, CxfConsumer just set the continuation timeout to be 0, which means the continuation suspend operation never timeout.)

Default: 30000
 Example: continuation=80000

cookieHandlerNoNew in Camel 2.19.0: Configure a cookie handler to maintain a HTTP session

The serviceName and portName are QNames, so if you provide them be sure to prefix them with their {namespace} as shown in the examples above.

The descriptions of the dataformats

DataFormat

Description

POJO

POJOs (Plain old Java objects) are the Java parameters to the method being invoked on the target server. Both Protocol and Logical JAX-WS handlers are supported.

PAYLOAD

PAYLOAD is the message payload (the contents of the soap:body) after message configuration in the CXF endpoint is applied. Only Protocol JAX-WS handler is supported. Logical JAX-WS handler is not supported.

MESSAGE

MESSAGE is the raw message that is received from the transport layer. It is not suppose to touch or change Stream, some of the CXF interceptors will be removed if you are using this kind of DataFormat so you can't see any soap headers after the camel-cxf consumer and JAX-WS handler is not supported.

CXF_MESSAGE

New in Camel 2.8.2, CXF_MESSAGE allows for invoking the full capabilities of CXF interceptors by converting the message from the transport layer into a raw SOAP message

You can determine the data format mode of an exchange by retrieving the exchange property, CamelCXFDataFormat. The exchange key constant is defined in org.apache.camel.component.cxf.CxfConstants.DATA_FORMAT_PROPERTY

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:{snippet:id=processSoapHeaderRoute|lang=xml|url=camel/trunk/components/camel-cxf/src/test/resources/org/apache/camel/component/cxf/soap/headers/CxfMessageHeadersRelayTest-context.xml}

...

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.{snippet:id=InsertResponseOutHeaderProcessor|lang=java|url=camel/trunk/components/camel-cxf/src/test/java/org/apache/camel/component/cxf/soap/headers/CxfMessageHeadersRelayTest.java}

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).{snippet:id=payload|lang=java|url=camel/trunk/components/camel-cxf/src/test/java/org/apache/camel/component/cxf/

...

CxfPayLoadSoapHeaderTest.java}Since Camel 2.16.0, you can also use the same way as described in sub-chapter "How to get and set SOAP headers in POJO mode" to set or get the SOAP headers. So, you can use now the header "org.apache.cxf.headers.Header.list" to get and set a list of SOAP headers.This does also mean that if you have a route that forwards from one Camel-cxf endpoint to another (SOAP Client -> Camel -> CXF service), now also the SOAP headers sent by the SOAP client are forwarded to the CXF service. If you do not want that these headers are forwarded you have to remove them in the Camel header "org.apache.cxf.headers.Header.list".

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{snippet:id=FaultDefine|lang=java|url=camel/trunk/components/camel-cxf/src/test/java/org/apache/camel/component/cxf/CxfCustomizedExceptionTest.java}

...

Then

...

throw

...

it

...

as

...

you

...

like

...

{snippet:id=ThrowFault|lang=java|url=camel/trunk/components/camel-cxf/src/test/java/org/apache/camel/component/cxf/CxfCustomizedExceptionTest.java}

...

If

in

format,

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.){snippet:id=enableMtom|lang=xml|url=camel/trunk/components/camel-cxf/src/test/resources/org/apache/camel/component/cxf/mtom/CxfMtomRouterPayloadModeTest-context.xml}

...

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

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).
