CXF ComponentThe 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 formatcxf: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
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
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 modeCXF'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 optionThere 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: Changes since Release 2.0
Configure the CXF endpoints with SpringYou 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. <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:cxf="http://activemq.apache.org/camel/schema/cxfEndpoint" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd http://activemq.apache.org/camel/schema/cxfEndpoint http://activemq.apache.org/camel/schema/cxf/camel-cxf-1.6.0.xsd http://activemq.apache.org/camel/schema/spring http://activemq.apache.org/camel/schema/spring/camel-spring.xsd "> <cxf:cxfEndpoint id="routerEndpoint" address="http://localhost:9003/CamelContext/RouterPort" serviceClass="org.apache.hello_world_soap_http.GreeterImpl"/> <cxf:cxfEndpoint id="serviceEndpoint" address="http://localhost:9000/SoapContext/SoapPort" wsdlURL="testutils/hello_world.wsdl" serviceClass="org.apache.hello_world_soap_http.Greeter" endpointName="s:SoapPort" serviceName="s:SOAPService" xmlns:s="http://apache.org/hello_world_soap_http" /> <camelContext id="camel" xmlns="http://activemq.apache.org/camel/schema/spring"> <route> <from uri="cxf:bean:routerEndpoint" /> <to uri="cxf:bean:serviceEndpoint" /> </route> </camelContext> </beans> NOTE In Camel 2.x we change to use {{http://camel.apache.org/schema/cxf}} as the CXF endpoint's target namespace. <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:cxf="http://camel.apache.org/schema/cxf" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd http://camel.apache.org/schema/cxf http://camel.apache.org/schema/cxf/camel-cxf.xsd http://camel.apache.org/schema/spring http://camel.apache.org/schema/spring/camel-spring.xsd "> ... 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:

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 formatThe 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 and return exchange.getOut().setFault(true); exchange.getOut().setBody(fault); return; } 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 formatThe 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 formatPAYLOAD 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. 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 get and set SOAP headers in POJO modePOJO 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: <route> <from uri="cxf:bean:routerRelayEndpointWithInsertion"/> <process ref="InsertRequestOutHeaderProcessor" /> <to uri="cxf:bean:serviceRelayEndpointWithInsertion"/> <process ref="InsertResponseOutHeaderProcessor" /> </route> In 2.x 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. public static class InsertResponseOutHeaderProcessor implements Processor { public void process(Exchange exchange) throws Exception { List<SoapHeader> soapHeaders = (List)exchange.getIn().getHeader(Header.HEADER_LIST); // Insert a new header String xml = "<?xml version=\"1.0\" encoding=\"utf-8\"?><outofbandHeader " + "xmlns=\"http://cxf.apache.org/outofband/Header\" hdrAttribute=\"testHdrAttribute\" " + "xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\" soap:mustUnderstand=\"1\">" + "<name>New_testOobHeader</name><value>New_testOobHeaderValue</value></outofbandHeader>"; SoapHeader newHeader = new SoapHeader(soapHeaders.get(0).getName(), DOMUtils.readXml(new StringReader(xml)).getDocumentElement()); // make sure direction is OUT since it is a response message. newHeader.setDirection(Direction.DIRECTION_OUT); //newHeader.setMustUnderstand(false); soapHeaders.add(newHeader); } } In 1.x SOAP headers are not propagated to and from Camel Message headers. Users have to go deeper into CXF APIs to access SOAP headers. Also, accessing the SOAP headers in a request message is slight different than in a response message. The InsertRequestOutHeaderProcessor and InsertResponseOutHeaderProcessor are as follow. public static class InsertRequestOutHeaderProcessor implements Processor { public void process(Exchange exchange) throws Exception { CxfMessage message = exchange.getIn().getBody(CxfMessage.class); Message cxf = message.getMessage(); List<SoapHeader> soapHeaders = (List)cxf.get(Header.HEADER_LIST); // Insert a new header String xml = "<?xml version=\"1.0\" encoding=\"utf-8\"?><outofbandHeader " + "xmlns=\"http://cxf.apache.org/outofband/Header\" hdrAttribute=\"testHdrAttribute\" " + "xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\" soap:mustUnderstand=\"1\">" + "<name>New_testOobHeader</name><value>New_testOobHeaderValue</value></outofbandHeader>"; SoapHeader newHeader = new SoapHeader(soapHeaders.get(0).getName(), DOMUtils.readXml(new StringReader(xml)).getDocumentElement()); // make sure direction is IN since it is a request message. newHeader.setDirection(Direction.DIRECTION_IN); //newHeader.setMustUnderstand(false); soapHeaders.add(newHeader); } } public static class InsertResponseOutHeaderProcessor implements Processor { public void process(Exchange exchange) throws Exception { CxfMessage message = exchange.getIn().getBody(CxfMessage.class); Map responseContext = (Map)message.getMessage().get(Client.RESPONSE_CONTEXT); List<SoapHeader> soapHeaders = (List)responseContext.get(Header.HEADER_LIST); // Insert a new header String xml = "<?xml version=\"1.0\" encoding=\"utf-8\"?><outofbandHeader " + "xmlns=\"http://cxf.apache.org/outofband/Header\" hdrAttribute=\"testHdrAttribute\" " + "xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\" soap:mustUnderstand=\"1\">" + "<name>New_testOobHeader</name><value>New_testOobHeaderValue</value></outofbandHeader>"; SoapHeader newHeader = new SoapHeader(soapHeaders.get(0).getName(), DOMUtils.readXml(new StringReader(xml)).getDocumentElement()); // make sure direction is OUT since it is a response message. newHeader.setDirection(Direction.DIRECTION_OUT); //newHeader.setMustUnderstand(false); soapHeaders.add(newHeader); } } How to get and set SOAP headers in PAYLOAD modeWe'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"). In 2.x Once you obtain a CxfPayload object, you can invoke the CxfPayload.getHeaders() method that returns a List of DOM Elements (SOAP headers). from(routerEndpointURI).process(new Processor() { @SuppressWarnings("unchecked") public void process(Exchange exchange) throws Exception { CxfPayload<SoapHeader> payload = exchange.getIn().getBody(CxfPayload.class); List<Element> elements = payload.getBody(); assertNotNull("We should get the elements here", elements); assertEquals("Get the wrong elements size", 1, elements.size()); assertEquals("Get the wrong namespace URI", "http://camel.apache.org/pizza/types", elements.get(0).getNamespaceURI()); List<SoapHeader> headers = payload.getHeaders(); assertNotNull("We should get the headers here", headers); assertEquals("Get the wrong headers size", headers.size(), 1); assertEquals("Get the wrong namespace URI", ((Element)(headers.get(0).getObject())).getNamespaceURI(), "http://camel.apache.org/pizza/types"); } }) .to(serviceEndpointURI); *In 1.x" You can get/set to the CXF Message by the key "org.apache.cxf.headers.Header.list" which is a constant defined in CXF (org.apache.cxf.headers.Header.HEADER_LIST). from(routerEndpointURI).process(new Processor() { @SuppressWarnings("unchecked") public void process(Exchange exchange) throws Exception { Message inMessage = exchange.getIn(); CxfMessage message = (CxfMessage) inMessage; List<Element> elements = message.getMessage().get(List.class); assertNotNull("We should get the payload elements here" , elements); assertEquals("Get the wrong elements size" , elements.size(), 1); assertEquals("Get the wrong namespace URI" , elements.get(0).getNamespaceURI(), "http://camel.apache.org/pizza/types"); List<SoapHeader> headers = CastUtils.cast((List<?>)message.getMessage().get(Header.HEADER_LIST)); assertNotNull("We should get the headers here", headers); assertEquals("Get the wrong headers size", headers.size(), 1); assertEquals("Get the wrong namespace URI" , ((Element)(headers.get(0).getObject())).getNamespaceURI(), "http://camel.apache.org/pizza/types"); } }) .to(serviceEndpointURI); SOAP headers are not available in MESSAGE modeSOAP headers are not available in MESSAGE mode as SOAP processing is skipped. How to throw a SOAP Fault from CamelIf you are using a camel-cxf endpoint to consume the SOAP request, you may need to throw the SOAP Fault from the camel context. 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 contextcxf 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());
Attachment SupportPOJO 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 since 2.1. So, it is possible to retreive attachments by Camel Message API DataHandler Message.getAttachment(String id)
Payload Mode: MTOM is supported since 2.1. Attachments can be retrieve by Camel Message APIs mentioned above. SOAP with Attachment is not supported as there is no SOAP processing in this mode. To enable MTOM, set the CXF endpoint property "mtom_enabled" to true. (I believe you can only do it with Spring.) <cxf:cxfEndpoint id="routerEndpoint" address="http://localhost:9091/jaxws-mtom/hello" wsdlURL="mtom.wsdl" serviceName="ns:HelloService" endpointName="ns:HelloPort" xmlns:ns="http://apache.org/camel/cxf/mtom_feature"> <cxf:properties> <!-- enable mtom by setting this property to true --> <entry key="mtom-enabled" value="true"/> <!-- set the camel-cxf endpoint data fromat to PAYLOAD mode --> <entry key="dataFormat" value="PAYLOAD"/> </cxf:properties> You can produce a Camel message with attachment to send to a CXF endpoint in Payload mode. Exchange exchange = context.createProducerTemplate().send("direct:testEndpoint", new Processor() { public void process(Exchange exchange) throws Exception { exchange.setPattern(ExchangePattern.InOut); List<Element> elements = new ArrayList<Element>(); elements.add(DOMUtils.readXml(new StringReader(MtomTestHelper.REQ_MESSAGE)).getDocumentElement()); CxfPayload<SoapHeader> body = new CxfPayload<SoapHeader>(new ArrayList<SoapHeader>(), elements); exchange.getIn().setBody(body); exchange.getIn().addAttachment(MtomTestHelper.REQ_PHOTO_CID, new DataHandler(new ByteArrayDataSource(MtomTestHelper.REQ_PHOTO_DATA, "application/octet-stream"))); exchange.getIn().addAttachment(MtomTestHelper.REQ_IMAGE_CID, new DataHandler(new ByteArrayDataSource(MtomTestHelper.requestJpeg, "image/jpeg"))); } }); // process response CxfPayload<SoapHeader> out = exchange.getOut().getBody(CxfPayload.class); Assert.assertEquals(1, out.getBody().size()); Map<String, String> ns = new HashMap<String, String>(); ns.put("ns", MtomTestHelper.SERVICE_TYPES_NS); ns.put("xop", MtomTestHelper.XOP_NS); XPathUtils xu = new XPathUtils(ns); Element ele = (Element)xu.getValue("//ns:DetailResponse/ns:photo/xop:Include", out.getBody().get(0), XPathConstants.NODE); String photoId = ele.getAttribute("href").substring(4); // skip "cid:" ele = (Element)xu.getValue("//ns:DetailResponse/ns:image/xop:Include", out.getBody().get(0), XPathConstants.NODE); String imageId = ele.getAttribute("href").substring(4); // skip "cid:" DataHandler dr = exchange.getOut().getAttachment(photoId); Assert.assertEquals("application/octet-stream", dr.getContentType()); MtomTestHelper.assertEquals(MtomTestHelper.RESP_PHOTO_DATA, IOUtils.readBytesFromStream(dr.getInputStream())); dr = exchange.getOut().getAttachment(imageId); Assert.assertEquals("image/jpeg", dr.getContentType()); BufferedImage image = ImageIO.read(dr.getInputStream()); Assert.assertEquals(560, image.getWidth()); Assert.assertEquals(300, image.getHeight()); You can also consume a Camel message received from a CXF endpoint in Payload mode. public static class MyProcessor implements Processor { @SuppressWarnings("unchecked") public void process(Exchange exchange) throws Exception { CxfPayload<SoapHeader> in = exchange.getIn().getBody(CxfPayload.class); // verify request Assert.assertEquals(1, in.getBody().size()); Map<String, String> ns = new HashMap<String, String>(); ns.put("ns", MtomTestHelper.SERVICE_TYPES_NS); ns.put("xop", MtomTestHelper.XOP_NS); XPathUtils xu = new XPathUtils(ns); Element ele = (Element)xu.getValue("//ns:Detail/ns:photo/xop:Include", in.getBody().get(0), XPathConstants.NODE); String photoId = ele.getAttribute("href").substring(4); // skip "cid:" Assert.assertEquals(MtomTestHelper.REQ_PHOTO_CID, photoId); ele = (Element)xu.getValue("//ns:Detail/ns:image/xop:Include", in.getBody().get(0), XPathConstants.NODE); String imageId = ele.getAttribute("href").substring(4); // skip "cid:" Assert.assertEquals(MtomTestHelper.REQ_IMAGE_CID, imageId); DataHandler dr = exchange.getIn().getAttachment(photoId); Assert.assertEquals("application/octet-stream", dr.getContentType()); MtomTestHelper.assertEquals(MtomTestHelper.REQ_PHOTO_DATA, IOUtils.readBytesFromStream(dr.getInputStream())); dr = exchange.getIn().getAttachment(imageId); Assert.assertEquals("image/jpeg", dr.getContentType()); MtomTestHelper.assertEquals(MtomTestHelper.requestJpeg, IOUtils.readBytesFromStream(dr.getInputStream())); // create response List<Element> elements = new ArrayList<Element>(); elements.add(DOMUtils.readXml(new StringReader(MtomTestHelper.RESP_MESSAGE)).getDocumentElement()); CxfPayload<SoapHeader> body = new CxfPayload<SoapHeader>(new ArrayList<SoapHeader>(), elements); exchange.getOut().setBody(body); exchange.getOut().addAttachment(MtomTestHelper.RESP_PHOTO_CID, new DataHandler(new ByteArrayDataSource(MtomTestHelper.RESP_PHOTO_DATA, "application/octet-stream"))); exchange.getOut().addAttachment(MtomTestHelper.RESP_IMAGE_CID, new DataHandler(new ByteArrayDataSource(MtomTestHelper.responseJpeg, "image/jpeg"))); } } Message Mode: Attachments are not supported as it does not process the message at all. 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, JAXWS(new to camel2.1) annotated service bean.) Note: CxfBeanEndpoint is a ProcessorEndpoint so it has no consumers. It works similarly to a Bean component. URI formatcxfbean: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
Headers
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 SampleThis 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. <route> <from uri="jetty:http://localhost:9000?matchOnUriPrefix=true" /> <to uri="cxfbean:customerServiceBean" /> </route> 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> <bean class="org.apache.camel.wsdl_first.PersonImpl" id="jaxwsBean" /> 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)); See Also |
