    CXF proxy webservice, camel route and spring


      Hello everybody,


      I would like to establish a CXF webservice as a proxy, in order to inject a request in a camel route.


      Here is a general schema :

      External Call => Proxy WebService => camel route => response at the end of the route


      I found an example with camel 2.7 which looks like what I want (camel-example-cxf-proxy), but I failed to deploy it on servicemix 4.2 despite instructions.


      My webservice is generated from a wsdl, and works correctly with a simple HelloWorld. The problem is that I can't inject this webservice's calls in the camel route, and send a response when the route is completed.


      I think the <cxfbc:consumer> tag is the one that should be used, but I saw in the camel example that the <cxf:cxfEndpoint> tag is used. What is the difference ?


      Could you help me by telling me how to achieve this ?


      Thanks a lot !

          You may want to look at some webinars covering web services with ServiceMix and Camel. There are 3 webinars in total



          The <cxfbc:consumer> is the old JBI component.

          The <cxf:cxfEndpoint> is the Apache CXF / Camel component.


          JBI is discouraged to use for new projects.

            And you may want to pickup and try SMX 4.3. You can download it from here http://fusesource.com/downloads/. The Camel proxy example should work on that version.


            SMX 4.2 is about 1 year old and its recommended to upgrade.

              Hello davsclaus,


              Thank you very much for your answer.


              Unfortunetaly, I failed again when trying with SMX 4.3. I think I missed something about how it works...


              The Junit test (and the main class) works that's why I think all the code is good.


              How can i deploy this example on SMX ? I try to copy the camel-example-cxf-proxy-2.7.1.jar into the deploy folder. After that the bundle is in "installed" state and i can't see the wsdl at this address : http://localhost:9080/camel-example-cxf-proxy/webservices/incident?wsdl


              thanks again for your help

                After some changement in the pom.xml i get the following stack trace when deploying the bundle :

                  Ok all is good now :).


                  Thanks for your help. In order to deploy the camel-cxf-proxy into SMX 4.3 :


                  - Change the pom.xml to specify a version (2.6.0) for camel dependencies

                  - enable camel-cxf and camel-http in SMX with the command :

                     features:install camel-cxf

                     features:install camel-http


                  Hope it helps


                  Thanks again
