/**
* This class helps take a {@link org.apache.cxf.service.Service} and
* expose as a server side endpoint.
* If there is no Service, it can create one for you using a
* {@link ReflectionServiceFactoryBean}.
*
* For most scenarios you'll want to just have the ServerFactoryBean handle everything
* for you. In such a case, usage might look like this:
*
*
* ServerFactoryBean sf = new ServerFactoryBean();
* sf.setServiceClass(MyService.class);
* sf.setAddress("http://localhost:8080/MyService");
* sf.create();
*
*
* You can also get more advanced and customize the service factory used:
*
* ReflectionServiceFactory serviceFactory = new ReflectionServiceFactory();
* serviceFactory.setServiceClass(MyService.class);
* ..
* \/\/ Customize service factory here...
* serviceFactory.setWrapped(false);
* ...
* ServerFactoryBean sf = new ServerFactoryBean();
* sf.setServiceFactory(serviceFactory);
* sf.setAddress("http://localhost:8080/MyService");
* sf.create();
*
