CXF Example OSGi Blueprint

Available as of Camel 2.8

A simple example which receives web service calls (via a CXF consumer, using bean binding)
and writes these requests into the file system. It's not a very useful use case, but the goal
of this example is to show you how you can use the CXF consumer component in an OSGI
environment with the OSGI HTTP service. If your target container is Apache Karaf or Apache
ServiceMix, you can use PAX Web to setup and start an OSGI HTTP service. All Camel
bundles using a Camel CXF consumer can use this HTTP service without needing to start
individual Jetty instances. Another advantage is that all provided services can now share
the same port.

This example is located in the examples/camel-example-cxf-blueprint directory of the Camel distribution.
There is a README.txt file with instructions how to run it.

You will need to compile this example first:

  mvn install

To run the example on Apache ServiceMix 4.x or Apache Karaf 2.x

1) launch the server

  karaf.bat
  

Note for Karaf 2.2.x:
a) edit the etc/jre.properties file to add the following packages to be exported

      jre-1.6=, \
      com.sun.org.apache.xerces.internal.dom, \
      com.sun.org.apache.xerces.internal.jaxp, \

b) from the same file comment out the following exports already provided by the bundles
that will be imported next: javax.xml.bind*, javax.jws*, javax.xml.soap*, javax.xml.ws*,
javax.activation, javax.annotation, javax.xml.stream*.

2) Add features required

 
   features:addUrl mvn:org.apache.camel.karaf/apache-camel/2.9.0/xml/features
   features:install war
   features:install cxf
   features:install camel-jaxb
   features:install camel-blueprint
   features:install camel-cxf
  

Note: Apache Camel 2.9.0 is being used above, but you should of course change the
version number to the exact version of Camel being used.

3) Deploy the example bundle

  osgi:install -s mvn:org.apache.camel/camel-example-cxf-blueprint
  

4) Verify that your service is available using the following url in the browser.
We assume you're using Karaf's default PAX Web configuration which uses
port 8181 for http. If you would like to use another port or https, change the configuration in
${KARAF_HOME}/etc/org.ops4j.pax.web.cfg. The immediate extension after the hostname and port ("cxf" in
the below URL) is configured via the org.apache.cxf.osgi.cfg file (Please see
http://team.ops4j.org/wiki//display/paxweb/Pax+Web for more information on PAX Web).

  http://localhost:8181/cxf/camel-example-cxf-blueprint/webservices/incident?wsdl
  

5) Start SOAPUI or use curl to send the request
Create a new project called camel-example-cxf-osgi
Point to the following url: http://localhost:8181/cxf/camel-example-cxf-blueprint/webservices/incident?wsdl
Open the request 1 (under camel-example-cxf-blueprint --> ReportIncidentBinding --> ReportIncident) and copy/paste a SOAP
message generated by the unit test, for example:

ex :
--> and the message formatted that you copy in SOAPUI

   
   <xml version="1.0" encoding="UTF-8"?>
   <soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
      <soap:Header />
      <soap:Body>
         <ns2:inputReportIncident xmlns:ns2="http://reportincident.example.camel.apache.org">
            <incidentId>111</incidentId>
            <incidentDate>2011-03-05</incidentDate>
            <givenName>Christian</givenName>
            <familyName>Mueller</familyName>
            <summary>Bla</summary>
            <details>Bla bla</details>
            <email>cmueller@apache.org</email>
            <phone>0049 69 1234567</phone>
         </ns2:inputReportIncident>
      </soap:Body>
   </soap:Envelope>
  

If you use curl, you need to save the upper message in a file (data.xml) first and use the blow command to send the message. 

curl -X POST -T data.xml -H "Content-Type: text/xml" http://localhost:8181/cxf/camel-example-cxf-osgi/webservices/incident

The response message looks like this

<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
  <soap:Body>
   <ns2:outputReportIncident xmlns:ns2="http://reportincident.example.camel.apache.org">
     <code>Accepted</code>
   </ns2:outputReportIncident>
  </soap:Body>
</soap:Envelope>

6) Check the file system
Check the folder "target/inbox/" in the Karaf base directory to see that a message has arrived.
