CXF Tomcat Example
Available as of Camel 2.5
This example is located in the examples/camel-example-cxf-tomcat directory of the Camel distribution.
There is a README.txt file with instructions how to run it.
If you use maven then you can easily package the example from the command line:
mvn package
About
This example demonstrates how you can use CXF to expose a web service in Camel using code first approach.
Implementation
The web service we want to expose is defined as an interface which has 2 operations:
In this example we are not using any JAX-WS annotations. You can use those annotations to fine control the web service wsdl contract.
In the Camel route we expose this web service very easily using the Camel CXF component.
All we have to do is to define an endpoint uri in the format
cxf:/incident?serviceClass=org.apache.camel.example.cxf.incident.IncidentService
This means Camel will expose the web service using the relative address /incident and the serviceClass parameter links to the interface which defines the code first approach.
In this example we want to be flexible, so if we add a 3rd operation to the web service we want it to be easily to add a route to handle this operation. Therefore we use the Recipient List EIP pattern to route to the route which handles the given operation. Notice how we use a Direct endpoint to link the routes.
Spring XML
In the Spring XML file we have to import some CXF mandatory imports. Notice we use the cxf-servlet to leverage HTTP Servlet with CXF.
web.xml
In the web.xml file we have just to setup Spring and CXF the usual way.
Running the example
This example runs in Apache Tomcat, so you will have to package the .war file and copy it to the webapp folder of Tomcat, which is the hot deploy folder.
Note: You have to use the version number of Camel you use. In this documentation we are using 2.5.0.
You can then use SoapUI or another web service client and send a request to the http://localhost:8080/camel-example-cxf-tomcat-2.5.0/webservices/incident url.
The wsdl is located at: http://localhost:8080/camel-example-cxf-tomcat-2.5.0/webservices/incident?wsdl.
And CXF outputs which web services it has from this url http://localhost:8080/camel-example-cxf-tomcat-2.5.0/webservices.
