Subject Re: Cayenne Generated Classes in Web Service API
Date Thu, 07 Jun 2007 16:24:33 GMT
Thanks for the reply.

I'm no Web Service guru, but my understanding is that the object is
transformed into an XML payload when sent from the client to the server.
Once the server receives the XML post, it unmarshals the XML into object
representations. That's why I figured I could get this to work very
easily/quickly.

I am going to keep looking into this and will post any helpful information I
find.
