19.21.5. Running Camel Examples

The Camel CXF (code first) example uses code-first to expose a web service in Camel running on JBoss EAP. It can be run using Maven.

Procedure 19.1. Task

  1. To build the example, navigate to its directory and run the following command: 
    mvn clean install
  2. To run the example, deploy it in JBoss EAP by copying the camel-example-cxf-tomcat.war located in the target directory to the standalone/deployments/ folder.
    The webservice is available in http://localhost:8080/camel-example-cxf-tomcat/webservices/incident?wsdl.

19.21.6. Sample Client With Camel CXF

This is what a sample client made with Camel CXF looks like: 
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
    <soap:Body>
        <ns1:reportIncident xmlns:ns1="http://incident.cxf.example.camel.apache.org/">
            <arg0>
                <details>Accounting Department</details>
                <email>johncitizen@acompany.com</email>
                <familyName>Citizen</familyName>
                <givenName>John</givenName>
                <incidentId>12345</incidentId>
                <summary>Incident</summary>
            </arg0>
        </ns1:reportIncident>
    </soap:Body>
</soap:Envelope>

<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
    <soap:Body>
        <ns1:statusIncident xmlns:ns1="http://incident.cxf.example.camel.apache.org/">
            <arg0>
                <incidentId>12345</incidentId>
            </arg0>
        </ns1:statusIncident>
    </soap:Body>
</soap:Envelope>

19.21.7. Camel Servlet Without Spring Example

Procedure 19.2. Task
