ServiceMix CXF SE

ServiceMix CXF SE component is a JBI Service Engine exposing (annotated) POJO as services on the JBI Bus.

It uses Apache CXF internally to perform service invocations and xml marshaling.

Features:

• jsr181 JSR-181 annotations
• jaxb2JAXB2/aegisAegis/xmlbeans XMLBeans databinding
• wsdl WSDL auto generation
• java Java proxy support
• MTOM / attachments support

Installation

...

• drop the installer zip in an hotdeploy directory monitored by ServiceMix
• using ant tasks

Maven Archetype

You can use the servicemix-cxf-se-service-unit archetype to create a CXF SE Service Unit (including a simple sample POJO):

mvn archetype:create \
  -DarchetypeGroupId=org.apache.servicemix.tooling \
  -DarchetypeArtifactId=servicemix-cxf-se-service-unit \
  -DarchetypeVersion=2010.01 \
  -DgroupId=your.group.id \
  -DartifactId=your.artifact.id \
  -Dversion=your-version

Deployment

You can deploy Service Units containing a file named xbean.xml for activating consumer and provider endpoints.

This xml file should respect the given syntax, though this is a spring based xml configuration file
See a full example here.  Note that you have to define the cxf-se namespace with

...

<beans xmlns:cxfse="http://servicemix.apache.org/cxfse/1.0">
    ...
</beans>

Once you've customized the service unit, simply install the SU:

mvn install

<dependency>
  <groupId>your.group.id</groupId>
  <artifactId>your.artifact.id</artifactId>
  <version>your-version</version>
</dependency>

Endpoint Configuration

The CXF SE endpoint provides a property named pojo. You can expose any POJO which contains the @WebService annotation.

A simple example follows

Any numbers of endpoints can be specified in the xbean.xml file.

As the main purpose is to expose a POJO, you will have to include the needed class files / jars in the service unit and reference them using the following tags in your xbean.xml configuration file:

<classpath>
  <location>.</location>
</classpath>

This will add the content of the location tags (relative to the unzipped service unit) to the classpath. The previous configuration will just add the class files contained in the service unit, as if it is a plain jar.

If you want to embed jars, just use something like

<classpath>
  <location>lib/foo.jar</location>
</classpath>

Endpoint

A few examples:

<cxfse:endpoint>
   <cxfse:pojo>
     <bean class="org.apache.cxf.calculator.CalculatorImpl">
     </bean>
   </cxfse:pojo>
</cxfse:endpoint>

You can use a proxy (see Proxies section of this page):

<cxfse:endpoint>
  <cxfse:pojo>
     <bean class="org.apache.servicemix.cxfse.GreeterImplForClientProxy">
       <property name="calculator">
          <cxfse:proxy service="calculator:CalculatorService" context="#context" type="org.apache.cxf.calculator.CalculatorPortType" />
       </property>
     </bean>
 </cxfse:pojo>
</cxfse:endpoint>

...

You can find a whole context injection test case here

Lightweight mode

The servicemix-cxf-se component can also be configured in a spring/xbean configuration file, for use in an embedded ServiceMix. Here is an example of such a configuration:

<sm:activationSpec>
  <sm:component>
      <cxfse:component>
      	<cxfse:endpoints>
           <cxfse:endpoint>
              <cxfse:pojo>
                 <bean class="org.apache.cxf.calculator.CalculatorImpl"/>
              </cxfse:pojo>
           </cxfse:endpoint>
      	</cxfse:endpoints>
      </cxfse:component>
  </sm:component>
</sm:activationSpec>

Proxies

You can create java proxies for JBI endpoints, provided that they expose a WSDL.

...

From a cxfse CXF SE Service Unit, it could be used as following:

...

MTOM is supported for the following classes:

• DataSource
• DataHandlerunmigrated-wiki-markup
• byte\[\]

If you have a bean with the following method:

...

<cxfse:endpoint>
  <cxfse:pojo>inFaultInterceptors>
    <bean class="org.apache.cxf.calculatorinterceptor.CalculatorImplLoggingInInterceptor"/>
    </bean>
  </cxfse:pojo>inFaultInterceptors>
  <cxfse:inInterceptors>
    <bean class="org.apache.cxf.interceptor.LoggingInInterceptor"/>
  </cxfse:inInterceptors>
  <cxfse:outInterceptors>outFaultInterceptors>
    <bean class="org.apache.cxf.interceptor.LoggingOutInterceptor"/>
  </cxfse:outInterceptors>outFaultInterceptors>
  <cxfse:inFaultInterceptors>outInterceptors>
    <bean class="org.apache.cxf.interceptor.LoggingInInterceptorLoggingOutInterceptor"/>
  </cxfse:inFaultInterceptors>outInterceptors>
  <cxfse:outFaultInterceptors>pojo>
    <bean class="org.apache.cxf.interceptorcalculator.LoggingOutInterceptor"/>CalculatorImpl">
    </bean>
  </cxfse:outFaultInterceptors>pojo>
</cxfse:endpoint>
