Subject Re: Cayenne and JAX-WS / JAXB

I never used JAXB, although I evaluated it briefly in the past. With  
everyone gradually moving to Java 6, it probably warrants a closer  
looks from us in Cayenne. More to the point, I think the annotations  
approach should work, but that will require some experimentation. So  
try it, and let us know if you run into any troubles.
