CXF Component

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:

<dependency>
   <groupId>org.apache.camel</groupId>
   <artifactId>camel-cxf</artifactId>
   <version>x.x.x</version>  <!-- use the same version as your Camel core version -->
</dependency>

URI format

cxf:bean:cxfEndpoint[?options]

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.

cxf://someAddress[?options]

Where someAddress specifies the CXF endpoint's address. With this URI format, most of the endpoint details are specified using options.

For either style above, you can append options to the URI as follows:

cxf:bean:cxfEndpoint?wsdlURL=wsdl/hello_world.wsdl&dataFormat=PAYLOAD

Options

Name Description Example Required? Default Value
wsdlURL The location of the WSDL. file://local/wsdl/hello.wsdl or wsdl/hello.wsdl No WSDL is obtained from endpoint address by default.
serviceClass The name of the SEI (Service Endpoint Interface) class. This class can have, but does not require, JSR181 annotations. 
Since 2.0, it is possible to use # notation to reference a serviceClass object instance from the registry.  E.g. serviceClass=#beanName. Please be advised that the referenced object cannot be a Proxy (Spring AOP Proxy is OK) as it relies on Object.getClass().getName() method for non Spring AOP Proxy.
org.apache.camel.Hello Yes  
serviceClassInstance In 1.6 or later (will be deprecated in 2.0), serviceClassInstance works like serviceClass=#beanName, which looks up a serviceObject instance from the registry. serviceClassInstance=beanName No (use either serviceClass or serviceClassInstance)  
serviceName The service name this service is implementing, it maps to the wsdl:service@name. {http:­//org.apache.camel}ServiceName Only if more than one serviceName in WSDL present  
portName The port name this service is implementing, it maps to the wsdl:port@name. {http:­//org.apache.camel}PortName Only if more than one portName under the serviceName is present  
dataFormat Which data type messages the CXF endpoint supports POJO, PAYLOAD, MESSAGE No POJO
relayHeaders Available since 1.6.1. Please see the Description of relayHeaders option section for this option in 2.0. Should a CXF endpoint relay headers along the route. Currently only available when dataFormat=POJO true, false No true
wrapped Which kind of operation that CXF endpoint producer will invoke true, false No false
setDefaultBus Will set the default bus when CXF endpoint create a bus by itself true, false No false
bus New in 2.0, use # notation to reference a bus object from the registry. The referenced object must be an instance of org.apache.cxf.Bus.
bus=#busName No Default bus created by CXF Bus Factory
cxfBinding New in 2.0, use # notation to reference a CXF binding object from the registry. The referenced object must be an instance of org.apache.camel.component.cxf.CxfBinding. cxfBinding=#bindingName
No
An instance of org.apache.camel.component.cxf.DefaultCxfBinding
headerFilterStrategy New in 2.0, use # notation to reference a header filter strategy object from the registry. The referenced object must be an instance of org.apache.camel.spi.HeaderFilterStrategy. headerFilterStrategy=#strategyName No
An instance of org.apache.camel.component.cxf.CxfHeaderFilterStrategy

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.

NOTE From CAMEL 1.5.1 , the serviceClass for a CXF producer (that is, the to endpoint) should be a Java interface.

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. JAX-WS handler is not supported.

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.

How to enable CXF's LoggingOutInterceptor in MESSAGE mode

CXF's LoggingOutInterceptor outputs outbound message that goes on the wire to logging system (Java Util Logging). Since the LoggingOutInterceptor is in PRE_STREAM phase (but PRE_STREAM phase is removed in MESSAGE mode), you have to configure LoggingOutInterceptor to be run during the WRITE phase. The following is an example.

<bean id="loggingOutInterceptor" class="org.apache.cxf.interceptor.LoggingOutInterceptor">
        <!--  it really should have been user-prestream but CXF does have such phase! -->
        <constructor-arg value="write"/> 
   </bean>
   		
<cxf:cxfEndpoint id="serviceEndpoint" address="http://localhost:9002/helloworld"
	serviceClass="org.apache.camel.component.cxf.HelloService">
	<cxf:outInterceptors>
	    <ref bean="loggingOutInterceptor"/>
	</cxf:outInterceptors>
	<cxf:properties>
		<entry key="dataFormat" value="MESSAGE"/>
	</cxf:properties>
</cxf:cxfEndpoint>

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.

Available in Release 1.6.1 and after (only in POJO 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 as this would introduce an ambiguity in name spaces to relay instance mappings.

<cxf:cxfEndpoint ...>
  <cxf:properties>
    <entry key="org.apache.camel.cxf.message.headers.relays">
      <list>
        <ref bean="customHeadersRelay"/>
      </list>
    </entry>
  </cxf:properties>
</cxf:cxfEndpoint>

<bean id="customHeadersRelay" class="org.apache.camel.component.cxf.soap.headers.CustomHeadersRelay"/>

Take a look at the tests that show how you'd be able to relay/drop headers here:

https://svn.apache.org/repos/asf/camel/branches/camel-1.x/components/camel-cxf/src/test/java/org/apache/camel/component/cxf/soap/headers/CxfMessageHeadersRelayTest.java

Changes since Release 2.0
  • POJO and PAYLOAD modes are supported. In POJO mode, only out-of-band message headers are available for filtering as the in-band headers have been processed and removed from header list by CXF. The in-band headers are incorporated into the MessageContentList in POJO mode. The camel-cxf component does make any attempt to remove the in-band headers from the MessageContentList as it does in 1.6.1. If filtering of in-band headers is required, please use PAYLOAD mode or plug in a (pretty straightforward) CXF interceptor/JAXWS Handler to the CXF endpoint.
  • The Message Header Relay mechanism has been merged into CxfHeaderFilterStrategy. The relayHeaders option, its semantics, and default value remain the same, but it is a property of CxfHeaderFilterStrategy.
    Here is an example of configuring it.
    <bean id="dropAllMessageHeadersStrategy" class="org.apache.camel.component.cxf.CxfHeaderFilterStrategy">
    
        <!--  Set relayHeaders to false to drop all SOAP headers -->
        <property name="relayHeaders" value="false"/>
        
    </bean>

    Then, your endpoint can reference the CxfHeaderFilterStrategy.

    <route>
        <from uri="cxf:bean:routerNoRelayEndpoint?headerFilterStrategy=#dropAllMessageHeadersStrategy"/>          
        <to uri="cxf:bean:serviceNoRelayEndpoint?headerFilterStrategy=#dropAllMessageHeadersStrategy"/>
    </route>
  • The MessageHeadersRelay interface has changed slightly and has been renamed to MessageHeaderFilter. It is a property of CxfHeaderFilterStrategy. Here is an example of configuring user defined Message Header Filters:
    <bean id="customMessageFilterStrategy" class="org.apache.camel.component.cxf.CxfHeaderFilterStrategy">
        <property name="messageHeaderFilters">
            <list>
                <!--  SoapMessageHeaderFilter is the built in filter.  It can be removed by omitting it. -->
                <bean class="org.apache.camel.component.cxf.SoapMessageHeaderFilter"/>          
                
                <!--  Add custom filter here -->    
                <bean class="org.apache.camel.component.cxf.soap.headers.CustomHeaderFilter"/>
            </list>
        </property>
    </bean>
  • Other than relayHeaders, there are new properties that can be configured in CxfHeaderFilterStrategy.
    Name Description type Required? Default value
    relayHeaders All message headers will be processed by Message Header Filters boolean No true (1.6.1 behavior)
    relayAllMessageHeaders All message headers will be propagated (without processing by Message Header Filters) boolean No false (1.6.1 behavior)
    allowFilterNamespaceClash If two filters overlap in activation namespace, the property control how it should be handled. If the value is true, last one wins. If the value is false, it will throw an exception boolean No false (1.6.1 behavior)

Configure the CXF endpoints with Spring

You can configure the CXF endpoint with the Spring configuration file shown below, and you can also embed the endpoint into the camelContext tags. When you are invoking the service endpoint, you can set the operationName and operationNameSpace headers to explicitly state which operation you are calling.

...

Be sure to include the JAX-WS schemaLocation attribute specified on the root beans element. This allows CXF to validate the file and is required. Also note the namespace declarations at the end of the <cxf:cxfEndpoint/> tag--these are required because the combined {namespace}localName syntax is presently not supported for this tag's attribute values.

The cxf:cxfEndpoint element supports many additional attributes:

Name Value
PortName The endpoint name this service is implementing, it maps to the wsdl:port@name. In the format of ns:PORT_NAME where ns is a namespace prefix valid at this scope.
serviceName The service name this service is implementing, it maps to the wsdl:service@name. In the format of ns:SERVICE_NAME where ns is a namespace prefix valid at this scope.
wsdlURL The location of the WSDL. Can be on the classpath, file system, or be hosted remotely.
bindingId The bindingId for the service model to use.
address The service publish address.
bus The bus name that will be used in the JAX-WS endpoint.
serviceClass The class name of the SEI (Service Endpoint Interface) class which could have JSR181 annotation or not.

It also supports many child elements:

Name Value
cxf:inInterceptors The incoming interceptors for this endpoint. A list of <bean> or <ref>.
cxf:inFaultInterceptors The incoming fault interceptors for this endpoint. A list of <bean> or <ref>.
cxf:outInterceptors The outgoing interceptors for this endpoint. A list of <bean> or <ref>.
cxf:outFaultInterceptors The outgoing fault interceptors for this endpoint. A list of <bean> or <ref>.
cxf:properties A properties map which should be supplied to the JAX-WS endpoint. See below.
cxf:handlers A JAX-WS handler list which should be supplied to the JAX-WS endpoint. See below.
cxf:dataBinding You can specify the which DataBinding will be use in the endpoint. This can be supplied using the Spring <bean class="MyDataBinding"/> syntax.
cxf:binding You can specify the BindingFactory for this endpoint to use. This can be supplied using the Spring <bean class="MyBindingFactory"/> syntax.
cxf:features The features that hold the interceptors for this endpoint. A list of {{<bean>}}s or {{<ref>}}s
cxf:schemaLocations The schema locations for endpoint to use. A list of {{<schemaLocation>}}s
cxf:serviceFactory The service factory for this endpoint to use. This can be supplied using the Spring <bean class="MyServiceFactory"/> syntax

You can find more advanced examples which show how to provide interceptors , properties and handlers here:
http://cwiki.apache.org/CXF20DOC/jax-ws-configuration.html

NOTE
You can use cxf:properties to set the camel-cxf endpoint's dataFormat and setDefaultBus properties from spring configuration file.

<cxf:cxfEndpoint id="testEndpoint" address="http://localhost:9000/router"
    serviceClass="org.apache.camel.component.cxf.HelloService"

How to make the camel-cxf component use log4j instead of java.util.logging

CXF's default logger is java.util.logging. If you want to change it to log4j, proceed as follows. Create a file, in the classpath, named META-INF/cxf/org.apache.cxf.logger. This file should contain the fully-qualified name of the class, org.apache.cxf.common.logging.Log4jLogger, with no comments, on a single line.

How to consume a message from a camel-cxf endpoint in POJO data format

The camel-cxf endpoint consumer POJO data format is based on the cxf invoker, so the message header has a property with the name of CxfConstants.OPERATION_NAME and the message body is a list of the SEI method parameters.

public class PersonProcessor implements Processor {

    private static final transient Log LOG = LogFactory.getLog(PersonProcessor.class);

    public void process(Exchange exchange) throws Exception {
        LOG.info("processing exchange in camel");

        BindingOperationInfo boi = (BindingOperationInfo)exchange.getProperty(BindingOperationInfo.class.toString());
        if (boi != null) {
            LOG.info("boi.isUnwrapped" + boi.isUnwrapped());
        }
        // Get the parameters list which element is the holder.
        MessageContentsList msgList = (MessageContentsList)exchange.getIn().getBody();
        Holder<String> personId = (Holder<String>)msgList.get(0);
        Holder<String> ssn = (Holder<String>)msgList.get(1);
        Holder<String> name = (Holder<String>)msgList.get(2);

        if (personId.value == null || personId.value.length() == 0) {
            LOG.info("person id 123, so throwing exception");
            // Try to throw out the soap fault message
            org.apache.camel.wsdl_first.types.UnknownPersonFault personFault =
                new org.apache.camel.wsdl_first.types.UnknownPersonFault();
            personFault.setPersonId("");
            org.apache.camel.wsdl_first.UnknownPersonFault fault =
                new org.apache.camel.wsdl_first.UnknownPersonFault("Get the null value of person name", personFault);
            // Since camel has its own exception handler framework, we can't throw the exception to trigger it
            // We just set the fault message in the exchange for camel-cxf component handling
            exchange.getFault().setBody(fault);
        }

        name.value = "Bonjour";
        ssn.value = "123";
        LOG.info("setting Bonjour as the response");
        // Set the response message, first element is the return value of the operation,
        // the others are the holders of method parameters
        exchange.getOut().setBody(new Object[] {null, personId, ssn, name});
    }

}

How to prepare the message for the camel-cxf endpoint in POJO data format

The camel-cxf endpoint producer is based on the cxf client API. First you need to specify the operation name in the message header, then add the method parameters to a list, and initialize the message with this parameter list. The response message's body is a messageContentsList, you can get the result from that list.

NOTE After Camel 1.5 , we change the message body from object array to message content list. If you still want to get the object array from the message body, you can get the body using message.getbody(Object[].class), as follows:

Exchange senderExchange = new DefaultExchange(context, ExchangePattern.InOut);
final List<String> params = new ArrayList<String>();
// Prepare the request message for the camel-cxf procedure
params.add(TEST_MESSAGE);
senderExchange.getIn().setBody(params);
senderExchange.getIn().setHeader(CxfConstants.OPERATION_NAME, ECHO_OPERATION);

Exchange exchange = template.send("direct:EndpointA", senderExchange);

org.apache.camel.Message out = exchange.getOut();
// The response message's body is an MessageContentsList which first element is the return value of the operation,
// If there are some holder parameters, the holder parameter will be filled in the reset of List.
// The result will be extract from the MessageContentsList with the String class type
MessageContentsList result = (MessageContentsList)out.getBody();
LOG.info("Received output text: " + result.get(0));
Map<String, Object> responseContext = CastUtils.cast((Map)out.getHeader(Client.RESPONSE_CONTEXT));
assertNotNull(responseContext);
assertEquals("We should get the response context here", "UTF-8", responseContext.get(org.apache.cxf.message.Message.ENCODING));
assertEquals("Reply body on Camel is wrong", "echo " + TEST_MESSAGE, result.get(0));

How to deal with the message for a camel-cxf endpoint in PAYLOAD data format

PAYLOAD means that you process the payload message from the SOAP envelope. You can use the Header.HEADER_LIST as the key to set or get the SOAP headers and use the List<Element> to set or get SOAP body elements.
Camel 1.x branch, you can get the List<Element> and header from the CXF Message, but if you want to set the response message, you need to create the CXF message using the CXF API.

protected RouteBuilder createRouteBuilder() {
    return new RouteBuilder() {
        public void configure() {
            from(SIMPLE_ENDPOINT_URI + "&dataFormat=PAYLOAD").to("log:info").process(new Processor() {
                public void process(final Exchange exchange) throws Exception {
                    Message inMessage = exchange.getIn();
                    if (inMessage instanceof CxfMessage) {
                        CxfMessage cxfInMessage = (CxfMessage) inMessage;
                        CxfMessage cxfOutMessage = (CxfMessage) exchange.getOut();
                        List<Element> inElements = cxfInMessage.getMessage().get(List.class);
                        List<Element> outElements = new ArrayList<Element>();
                        XmlConverter converter = new XmlConverter();
                        String documentString = ECHO_RESPONSE;
                        if (inElements.get(0).getLocalName().equals("echoBoolean")) {
                            documentString = ECHO_BOOLEAN_RESPONSE;
                        }
                        org.apache.cxf.message.Exchange ex = ((CxfExchange)exchange).getExchange();
                        Endpoint ep = ex.get(Endpoint.class);
                        org.apache.cxf.message.Message response = ep.getBinding().createMessage();
                        Document outDocument = converter.toDOMDocument(documentString);
                        outElements.add(outDocument.getDocumentElement());
                        response.put(List.class, outElements);
                        cxfOutMessage.setMessage(response);                            
                    }
                }
            });
        }
    };
}

Change in 2.0, CxfMessage.getBody() will return an org.apache.camel.component.cxf.CxfPayload object, which has getters for SOAP message headers and Body elements. This change enables decoupling the native CXF message from the Camel message.

protected RouteBuilder createRouteBuilder() {
    return new RouteBuilder() {
        public void configure() {
            from(SIMPLE_ENDPOINT_URI + "&dataFormat=PAYLOAD").to("log:info").process(new Processor() {
                public void process(final Exchange exchange) throws Exception {                        
                    CxfPayload<SoapHeader> requestPayload = exchange.getIn().getBody(CxfPayload.class);
                    List<Element> inElements = requestPayload.getBody();
                    List<Element> outElements = new ArrayList<Element>();
                    XmlConverter converter = new XmlConverter();
                    String documentString = ECHO_RESPONSE;
                    if (inElements.get(0).getLocalName().equals("echoBoolean")) {
                        documentString = ECHO_BOOLEAN_RESPONSE;
                    }
                    Document outDocument = converter.toDOMDocument(documentString);
                    outElements.add(outDocument.getDocumentElement());
                    // set the payload header with null
                    CxfPayload<SoapHeader> responsePayload = new CxfPayload<SoapHeader>(null, outElements);
                    exchange.getOut().setBody(responsePayload); 
                }
            });
        }
    };
}

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

SOAP_FAULT = new SoapFault(EXCEPTION_MESSAGE, SoapFault.FAULT_CODE_CLIENT);
Element detail = SOAP_FAULT.getOrCreateDetail();
Document doc = detail.getOwnerDocument();
Text tn = doc.createTextNode(DETAIL_TEXT);
detail.appendChild(tn);

Then throw it as you like

from(routerEndpointURI).setFaultBody(constant(SOAP_FAULT));

If your CXF endpoint is working in the MESSAGE data format, you could set the the SOAP Fault message in the message body and set the response code in the message header.

from(routerEndpointURI).process(new Processor() {

    public void process(Exchange exchange) throws Exception {
        Message out = exchange.getOut();
        // Set the message body with the 
        out.setBody(this.getClass().getResourceAsStream("SoapFaultMessage.xml"));
        // Set the response code here
        out.setHeader(org.apache.cxf.message.Message.RESPONSE_CODE, new Integer(500));

NOTE the response code setting only works in Camel's version >= 1.5.1

How to propagate a camel-cxf endpoint's request and response context

cxf client API provides a way to invoke the operation with request and response context. If you are using a camel-cxf endpoint producer to invoke the outside web service, you can set the request context and get response context with the following code:

CxfExchange exchange = (CxfExchange)template.send(getJaxwsEndpointUri(), new Processor() {
            public void process(final Exchange exchange) {
                final List<String> params = new ArrayList<String>();
                params.add(TEST_MESSAGE);
                // Set the request context to the inMessage
                Map<String, Object> requestContext = new HashMap<String, Object>();
                requestContext.put(BindingProvider.ENDPOINT_ADDRESS_PROPERTY, JAXWS_SERVER_ADDRESS);
                exchange.getIn().setBody(params);
                exchange.getIn().setHeader(Client.REQUEST_CONTEXT , requestContext);
                exchange.getIn().setHeader(CxfConstants.OPERATION_NAME, GREET_ME_OPERATION);
            }
        });
        org.apache.camel.Message out = exchange.getOut();
        // The output is an object array, the first element of the array is the return value
        Object[] output = out.getBody(Object[].class);
        LOG.info("Received output text: " + output[0]);
        // Get the response context form outMessage
        Map<String, Object> responseContext = CastUtils.cast((Map)out.getHeader(Client.RESPONSE_CONTEXT));
        assertNotNull(responseContext);
        assertEquals("Get the wrong wsdl opertion name", "{http://apache.org/hello_world_soap_http}greetMe", responseContext.get("javax.xml.ws.wsdl.operation").toString());

CXF Bean Component (2.0 or later)

The cxfbean: component allows other Camel endpoints to send exchange and invoke Web service bean objects. (Currently, it only supports JAXRS annotated service bean.)

Note: CxfBeanEndpoint is a ProcessorEndpoint so it has no consumers. It works similarly to a Bean component.

URI format

cxfbean:serviceBeanRef

Where serviceBeanRef is a registry key to look up the service bean object. If serviceBeanRef references a List object, elements of the List are the service bean objects accepted by the endpoint.

Options

Name Description Example Required? Default Value
cxfBeanBinding CXF bean binding specified by the # notation. The referenced object must be an instance of org.apache.camel.component.cxf.cxfbean.CxfBeanBinding. cxfBinding=#bindingName No An instance of org.apache.camel.component.cxf.cxfbean.DefaultCxfBeanBinding
bus CXF bus reference specified by the # notation. The referenced object must be an instance of org.apache.cxf.Bus. bus=#busName No Default bus created by CXF Bus Factory
headerFilterStrategy Header filter strategy specified by the # notation. The referenced object must be an instance of org.apache.camel.spi.HeaderFilterStrategy. headerFilterStrategy=#strategyName No An instance of org.apache.camel.component.cxf.CxfHeaderFilterStrategy
setDefaultBus Will set the default bus when CXF endpoint create a bus by itself. true, false No false

Headers

Name Description Type Required? Default Value In/Out Examples
CamelHttpCharacterEncoding (before 2.0-m2: CamelCxfBeanCharacterEncoding) Character encoding String No None In ISO-8859-1
CamelContentType (before 2.0-m2: CamelCxfBeanContentType) Content type String No */* In text/xml
CamelCxfBeanRequestBasePath The value of this header will be set in the CXF message as the Message.BASE_PATH property. It is needed by CXF JAX-RS processing. Basically, it is the scheme, host and port portion of the request URI. String Yes The Endpoint URI of the source endpoint in the Camel exchange In http://localhost:9000
CamelHttpPath (before 2.0-m2: CamelCxfBeanRequestPath) Request URI's path String Yes None In consumer/123
CamelHttpMethod (before 2.0-m2: CamelCxfBeanVerb) RESTful request verb String Yes None In GET, PUT, POST, DELETE
CamelHttpResponseCode HTTP response code Integer No
None Out
200

Note: Currently, CXF Bean component has (only) been tested with Jetty HTTP component it can understand headers from Jetty HTTP component without requiring conversion.

A Working Sample

This sample shows how to create a route that starts a Jetty HTTP server. The route sends requests to a CXF Bean and invokes a JAXRS annotated service.

First, create a route as follows. The from endpoint is a Jetty HTTP endpoint that is listening on port 9000. Notice that the matchOnUriPrefix option must be set to true because RESTful request URI will not match the endpoint's URI http:­//localhost:9000 exactly.

from("jetty:http://localhost:9000?matchOnUriPrefix=true").
        to("cxfbean:customerServiceBean");

The to endpoint is a CXF Bean with bean name customerServiceBean. The name will be looked up from the registry. Next, we make sure our service bean is available in Spring registry. We create a bean definition in the Spring configuration. In this example, we create a List of service beans (of one element). We could have created just a single bean without a List.

<util:list id="customerServiceBean">
	<bean class="org.apache.camel.component.cxf.jaxrs.testbean.CustomerService" />
</util:list>

That's it. Once the route is started, the web service is ready for business. A HTTP client can make a request and receive response.

url = new URL("http://localhost:9000/customerservice/orders/223/products/323");
in = url.openStream();
assertEquals("{\"Product\":{\"description\":\"product 323\",\"id\":323}}", CxfUtils.getStringFromInputStream(in));
