How to transform from Source(Document) to CXF Message?

[XiLai Dai]

Hi, there,

Now, we've implemented a Provide like this: 

@javax.xml.ws.ServiceMode(value = javax.xml.ws.Service.Mode.PAYLOAD)
@javax.xml.ws.WebServiceProvider()
public class ProviderBase implements 
javax.xml.ws.Provider<javax.xml.transform.Source> {

    //@javax.jws.WebMethod(exclude=true)
        public final Source invoke(Source request) {
        //how to transform request or return Source to Message, so we can add 
some custom properties class to it: 
        CustomInfo customInfo = new CustomInfo();
        message.put (CustomInfo.class, customInfo);
    }
}

So, in the invoke() method, how to transform request or return Source to 
Message?  so we can add some custom properties class to it, and then our 
Interceptor class can get them.

Thanks!
