CXF Example OSGi

Available as of Camel 2.8

Spring-DM vs. OSGi Blueprint

Icon

This example uses Spring DM for OSGi. There is another CXF Example OSGi Blueprint that uses Blueprint.

A simple example which receives web service calls (via a CXF consumer, using bean binding)
and writes these requests to 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-osgi directory of the Camel distribution.
There is a README.txt file with instructions how to run it.

You will need to compile the example first:

Remarks:

  • During the compilation phase, a unit test will be performed which simulates the
    client calling the web service exposed by our camel/cxf route.
  • In Eclipse, I have used the following option when starting the junit test case. This option tells
    CXF that it must use log4j : -Dorg.apache.cxf.Logger=org.apache.cxf.common.logging.Log4jLogger

To run the example on Apache ServiceMix 4.x or Apache Karaf 2.2.x

1) launch the server

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

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

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

4) Verify that your service is available using the following url in the browser.
We assume assuming the OOTB Karaf defaults you use the default PAX Web configuration which use the 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).

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-osgi/webservices/incident?wsdl
Open the request 1 (under camel-example-cxf-osgi --> ReportIncidentBinding --> ReportIncident) and copy/paste a SOAP
message generated by the unit test, for example:

--> and the message formatted that you copy in SOAPUI and send the message

 

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. 

 

The response message looks like this

 

 

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