programatically adding JAXWS request wrappers

[Jan Martiška <jm...@redhat.com>]

Hi,
once again I stumbled upon an issue when trying to implement WS-Eventing for CXF. I would like to know if there is any easy way how to make a JAXWS client use a request wrapper. I have this scenario - there is an interface from which I create a JAXWS client (using JaxWsProxyFactoryBean):

@WebService
@SOAPBinding(parameterStyle = SOAPBinding.ParameterStyle.BARE)
public interface CatastrophicEventSink {
    void earthquake(EarthquakeEvent ev);
}

and I need to "magically" change it into this:

@WebService
@SOAPBinding(parameterStyle = SOAPBinding.ParameterStyle.WRAPPED)
public interface CatastrophicEventSink {
    @RequestWrapper(localName = "NotifyEvent", targetNamespace = "http://some-namespace.com")
    void earthquake(EarthquakeEvent ev);
}

.. without having to write the other interface, that should be made somehow automatically.
We can suppose that the server on the other side will understand it and know that a request wrapper is used.
I tried some experiments and only found that wrappers are generated some insane way using ASM library and I wasn't able to understand how exactly it works.
Is there any (not very ugly) way to accomplish this?

Thanks!!
Jan

Are you working from a WSDL?  Then you can use a binding file as 
explained here: 
http://cxf.apache.org/docs/wsdl-to-java.html#WSDLtoJava-wrapperstyle. 
Note that the meaning of BARE and WRAPPED can be counterintuitive (as 
mentioned at that link), BARE may actually be what you want.

Not really, no.  Mostly because you end up with either a "mixed" method (request is wrapped, response unwrapped) which isn't supported, or a new method that doesn't match the original WSDL.   (unless this is also an @OneWay)
