For more details on how to migrate:

• Are you using the ObjectServiceFactory, AnnotationServiceFactory, or JAXWSServiceFactory? Go->
• Are you using services.xml? Go->
• Are you using the XFireServlet the Spring ServiceBean? Go->
• Are you using the Spring XFireExporterServiceBean? Go->
• Are you using the XFireServletSpring XFireExporter? Go->

Should I Migrate Yet?

...

There a couple small areas where we haven't replicated all of the XFire functionality yet. Namely the JiBX and XMLBeans databindings. These will be ported for CXF 2.1. databinding. The only other reason not to migrate to CXF that we see is a requirement for Java 1.4. Although, we would encourage users to take a look at using CXF on Java 1.4 via Retrotranslator.

Service Factories

XFire included serveral service factories for building services. CXF also includes service factories, but the concept has been improved somewhat to make them easier to use. CXF now includes the concept of ServerFactoryBeans which produce Servers, ClientFactoryBeans which produce Clients, and ClientProxyFactoryBeans which produce Client proxies.

Example ObjectServiceFactory Migration

ObjectServiceFactory osf = new ObjectServiceFactory();
Service service = osf.create(MyServiceInterface.class);
service.setInvoker(new BeanInvoker(new MyServiceImpl());

ServerFactoryBean sf = new ServerFactoryBean();
sf.getServiceFactory().setDataBinding(new AegisDatabinding();
sf.setServiceBean(new MyServiceImpl());
sf.setServiceClass(MyServiceInterface.class);
sf.setAddress("http://localhost:8080/myservice");
sf.create();

Example AnnotationServiceFactory Migration

AnnotationServiceFactory osf = new AnnotationServiceFactory();
Service service = osf.create(MyServiceInterface.class);
service.setInvoker(new BeanInvoker(new MyServiceImpl());

JaxWsServerFactoryBean sf = new JaxWsServerFactoryBean ();
sf.getServiceFactory().setDataBinding(new AegisDatabinding());
sf.setServiceClass(MyServiceImpl.class);
sf.setAddress("http://localhost:8080/myservice");
sf.create();

Example JAXWSServiceFactory Migration

JAXWSServiceFactory sf = new JAXWSServiceFactory();
Service service = sf.create(MyServiceImpl.class);
service.setInvoker(new BeanInvoker(new MyServiceImpl());

JaxWsServerFactoryBean sf = new JaxWsServerFactoryBean();
sf.setServiceClass(MyServiceImpl.class);
sf.setAddress("http://localhost:8080/myservice");
sf.create();

HTTP and Servlet Setup

CXF supports a much wider range of options for deploying your service over HTTP. XFire created a static mapping between the HTTP URL and the service name - i.e. a service named "HelloService" was accessible at http://localhost/services/HelloService. CXF on the other hand allows you to control the URL which your service is published on. This address is provided to CXF either through the setAddress() call on the ServerFactoryBeans or via your XML configuration.

Another improvement over XFire is that CXF will now transparently detect whether the CXFServlet is being used. If it is, your service will be available on that location. If it is not, CXF will automatically start an embedded Jetty instance (provided the cxf-rt-transports-http-jetty module is on your classpath). No more calls to XFireHttpServer are needed!

To set up the CXF servlet, please read the how-to on the Servlet Transport page.

To use the embedded Jetty instance, no extra work is needed. Simply follow the above ServiceFactory examples.

services.xml

XFire included support for deploying your services via a services.xml file. In CXF this file is named cxf.xml and will be loaded by the CXFServlet

<beans xmlns="http://xfire.codehaus.org/config/1.0">

<service xmlns:t="urn:my:namespace">
	<name>testservice</name>
	<serviceClass>org.example.TestService
	</serviceClass>
	<implementationClass>org.codehaus.xfire.spring.TestServiceImpl</implementationClass>

        </properties>

    </jaxws:implementor>
    <jaxws:properties>
      <entry key="foo" value="bar"/>
    </jaxws:properties>
    <jaxws:inInterceptors>
      <bean class="org.example.ExampleInterceptor"/>
    </jaxws:inInterceptors>
  </jaxws:endpoint>

</beans>

There are a few important things to note here on the differences:

• Many of these attributes are optional, such as the service name
• You don't need to specify a serviceClass if you are using JAX-WS as your service should be annotated with the @WebService.endpointInterface attribute.
• The equivalent of XFire Handlers is Interceptors inside CXF. They feature a much improved API!

The above sample is for JAX-WS/JSR181 services. For those developing services without annotations, here's an example for the Simple Frontend"
