Long Message Warning Hello, First of all thanks for all the great work in Camel and CFX.
We are planning to use CXF as our service stack for a new project and I am planning to use Camel for the routing needs. We use Tomcat as container and would like to know the feasibility of the following The CFX Web Service would be available through ServletTransport and with SOAP binding and would like to use the WebServiceProvider (no default data biding support) as we are planning to deal with the raw XML Message. Based on the content I would then route the message to various processors and external services(endpoints) and finally return the result to the request client (soap or REST). I have a sample solution for this now with CXF exposing a WebServiceProvider that would recieve the XML message and some basic home grown routing logic that works with beans defined in Spring context. I want to replace this part with Camel and is where I am experiencing trouble. As I understand CamelConsumer would inject a MessageObserver in the CXF chain and this in turn would use CamelInvoker to invoke the route before it request reaches the actual CXF endpoint. If this is right I could probably be able to get away having a WebServiceProvider SEI at all and have Camel Processors do the job of routing the requests to all my bean processors and external services (thrid party SOAP Services and such) . Anyway I started integrating my existing CFX service with a very basic Camel route with the following configuration and is loaded through a web application in Tomcat using SpringContextLoader. My intention was to route all incoming messages to the CFX endpoint to the bean processor or any other provider and then finally invoke the SEI and return the output to the requesting client. <?xml

the message clearly says the CXF imports defines the default cxf bus with name "cxf" and camel tries to use th same name for the routing reference.

But I noticed that CXF was building my service from WSDL and was not using Jax-WS WebServiceProvider. A quick look at the source told me that ServerFactoryBean created by the consumer is not a JaxWsServerFactoryBean as the CxfEndpointUtils.hasWebServiceAnnotation(cls) method just checks for the WebService annotation and does not consider the WebServiceProvider annotation. Without changing anything if I try to invoke the WebSerice (using SOAP UI) I get a Soap Fault with the message <soap:Fault> <faultcode>soap:Client</faultcode> <faultstring>Message part {http://simple.services.aswin.org/data}SimpleWebServiceRequest was not recognized.</faultstring> </soap:Fault> I can get past the errors if I modify the CxfEndUtils or change my SEI to be a WebService instead of a WebServiceProvider and am able to get the Camel Route running. But I hit some exceptions a and decided that I seek help so that I could find a solution faster In specific I have the following questions 1) Do we need a SEI at all or could we use Camel to intercept a request for a Abstract SEI definition and fullfill the role of the SEI. I could have multiple small services and processors cordinated by CAMEL in realizing the business function. 2) Do we need any specific configuration to enable Servlet Transport and interception of Messages? How could I setup the interceptor route for handling messages? And is there any specific routing or configuration needed for returning the results to the end client (two way channel?) 3) Any other thoughts on this. Any help would be really appreciated Thanks Aswin -- View this message in context: http://www.nabble.com/Camel-CXF-Spring-Tomcat-configuration-tp15350144s22882p15350144.html Sent from the Camel - Users mailing list archive at Nabble.com.
