Question

Instead of this

@XmlSeeAlso({User.class,Role.class,Function.class})

I would like something like this:

@XmlSeeAlso(Access.getWebServiceClasses())

Is it possible?

I want this since my webservice just contains interfaces and if I change the implementation I would just like to change in my factory so it returns the right classes instead of having to change in the webservice itself.

This isn’t possible, since annotation elements must be simple types (strings, primitives or classes (see annotations).

It is possible however (in CXF) to override org.apache.cxf.jaxws.support.JaxWsServiceFactoryBean.getExtraClass() method which, by default checks @XmlSeeAlso of the interface. My implementation returns additional ObjectFactory classes.

Chances are that you’re using <jaxws:endpoint /> in CXF’s Spring XML configuration. To be able to override this method, you have create few classes:

1. org.apache.cxf.jaxws.spring.EndpointDefinitionParser must use class derived from org.apache.cxf.jaxws.spring.EndpointDefinitionParser.SpringEndpointImpl (when using JAXWS 2.1) or from org.apache.cxf.jaxws22.spring.JAXWS22SpringEndpointImpl (JAXWS 2.2)
2. This class must call super.setServiceFactory() passing org.apache.cxf.jaxws.support.JaxWsServerFactoryBean with overriden getExtraClass()

3. You have to provide your own org.apache.cxf.jaxws.spring.NamespaceHandler (you can create derived class) for your own namespace (e.g. http://cxf.apache.org/jaxws/dynamic) which will register your own parser for jaxws:endpoint element:

   registerBeanDefinitionParser(“endpoint”, new EndpointDefinitionParser());

(sorry, I can’t provide full example – I’m writing from memory and CXF’s source code)
