This example is located in the examples/camel-example-cxf-proxy directory of the Camel distribution.
If you use Maven then you can easily run it from the command line using:
This example demonstrates how CXF can be used to proxy a real web service. For this example we want Camel to validate and enrich the input message before it's sent to the actual web service. We do this to ensure the data is correct and to have Camel automatically add in any missing information. In real life you may wish to use a proxy in cases where clients are sending bad/faulty data to a web service, and it's costly/not possible to update and fix those clients.
For this simple example both the Camel application and the real web service are in the same JVM. In production work the real web service may often be hosted on another server, etc.
In the Spring XML file we have defined the CXF proxy endpoint using the <cxf:cxfEndpoint> tag. The real web service is the Spring bean with the id realWebService.
As you can see in the Camel route we use a CXF consumer to proxy the web service. Then we route the message to the EnrichBean which validates and adds the missing information. Then we just use the HTTP component to send the web service request to the real web service.
The enrich bean is Java code which in our simple example will just set the incidentId parameter to the fixed value of 456. In your implementation you can of course do a lot more.
You start the example from the command line using the Maven goal mvn camel:run.
You can then use SoapUI or another web service client and send a request to the http://localhost:9080/camel-example-cxf-proxy/webservices/incident url. The wsdl is located at: http://localhost:9080/camel-example-cxf-proxy/webservices/incident?wsdl.
After making a SOAP request, check the console to see the SOAP request and response:
Here is a sample output from the console:
