MuleSoft Consuming Soap Web Service - CXF jax-ws-client Module
- 1. CONSUMING SOAP WEB SERVICE - MULESOFT CXF JAX-WS-CLIENT MODULE Vince Jason Soliza
- 2. Mulesoft CXF Jax-WS Client Module When using CXF inside of Mule, there are several different ways to consume web service. One is the WSDL First CXF JAX-WS Client: It builds a message processor which can use a JAX- WS client generated from WSDL.
- 3. JAX-WS-CLIENT WSDL / CONTRACT FIRST APPROACH
- 4. Create Stub Client with CXF: wsdl2java First we need to setup our maven configuration to create a stub client. CXF includes the wsdl2java utility that can generate Java stub client code to call any method on the service, and marshal and un-marshal request parameters and responses as Java objects for further processing. This generated stub client is the core of your connector.
- 5. Create Stub Client with CXF: wsdl2java The Java source files generated correspond to the service as described by the contents of the WSDL.
- 6. Create 2 Flows: Main Flow & CXF Client Flow
- 7. Main Flow Components • HTTP Listener – Accepts the request • Transform Message – Create request for web service consumer the output is XML • XML-to-JAXB-Object – Transform XML to JAXB-Object to be consumed by the JAX-WS-Client • Flow Reference – Reference to the Flow of EchoServiceFlow • Transform Message – Parse the response of EchoServiceFlow to XML
- 8. CXF Client Components • CXF – Jax-ws-client configuration • HTTP request – http request hold the configuration for the target endpoint
- 9. Request Configuration We used Transform Message to create a SOAP request, cxf:jax-ws-client requires jaxb-object as the acceptable request so we added xml-to-jaxb- object transformer after it.
- 10. Request Configuration Check in debug mode, the payload is an instance of EchoRequest.
- 11. Request Configuration Code Snippet: <dw:transform-message doc:name="Transform Message"> <dw:set-payload><![CDATA[%dw 1.0 %output application/xml %namespace echo http://www.whiteskylabs.com/wsdl/echo/ --- echo#EchoRequest: { EchoInfo: { Id: "1345", Name: "Mario Luigi", Description: "Mario Bros", OtherInfo: "Legendary" } } ]]></dw:set-payload> </dw:transform-message> <mulexml:jaxb-xml-to-object-transformer returnClass="com.whiteskylabs.wsdl.echo.EchoRequest" jaxbContext- ref="JAXB_Context" doc:name="XML to JAXB Object" />
- 12. cxf:jax-ws-client Configuration Configure the client with the following properties. • clientClass: The client class generated by CXF, which extends javax.xml.ws.Service. • port: The WSDL port to use for communicating with the service • wsdlLocation: The location of the WSDL for the service. Since we are using WSDL first client, CXF uses this to configure the client. • operation: The operation name to invoke on the web service.
- 13. cxf:jax-ws-client Configuration We put cxf:jax-ws-client into a new private flow, to wrap it as a SOAP web service consumer. code snippet: <flow name="EchoServiceFlow"> <cxf:jaxws-client operation="echo" clientClass="com.whiteskylabs.wsdl.echo.EchoService_Service" port="EchoServicePort" wsdlLocation="classpath:/EchoService.wsdl" doc:name="CXF" soapVersion="1.2" /> <http:request config-ref="HTTP_Request_Configuration" path="/echo-ws/ws/EchoService" method="POST" doc:name="HTTP" /> </flow>
- 14. Response Configuration The cxf:jax-ws-client response is also an object, but unlike with request it’s not in the form of JAXB-Object. We can directly use the Transform Message to parse it and create an XML response.
- 15. Response Configuration Check in debug mode, the payload is an instance of EchoResponse.
- 16. Response Configuration code snippet: <dw:transform-message doc:name="Transform Message"> <dw:set-payload><![CDATA[%dw 1.0 %output application/xml %namespace echo http://com.whiteskylabs/wsdl/echo/ --- { echo#EchoResponse: { echoResult: { echoInfo: { id: payload.echoResult.echoInfo.id, name: payload.echoResult.echoInfo.name, description: payload.echoResult.echoInfo.description, otherInfo: payload.echoResult.echoInfo.otherInfo } } } }]]></dw:set-payload> </dw:transform-message>
- 17. Test the application • Run the application in Anypoint Studio. • Send request through HTTP using Postman, browser or any client you prefer. • We can see in the screenshot below, the response of the soap web service we consumed using web service consumer.
- 18. Summary This slide describes how to consume web services using the CXF jax-ws-client message processor using WSDL first approach. It is still recommended to use the Web Service Consumer component instead of this whenever possible.
