Re: [JIRA] Created: (CAY-580) Cayenne-ropwsdl: initial submission of code.
Kevin,
Do you have any plans to evaluate this code and move it to Cayenne
main repository? This is pretty interesting stuff - I'd love to try
it, but didn't want to get too deep inside until it settles in the
main repo.
Michael - btw, another type of queries that should be fairly easy to
implement and give you access to many Cayenne capabilities is
NamedQuery (a pointer to a SQLTemplate, SelectQuery and
ProcedureQuery stored in a DataMap on the server).

More on cayenne-rop-wsdl

Michael,
I see some of your design-related notes in the code (e.g.
AxisConnection has a note about EntityResolver). Please do not be
afraid to post them here. We want to include this code in Cayenne at
some point, so let's discuss this in public.
Lots of this stuff is research... What I was hoping to achieve here is
1. expose what we have already in Hessian to the world in a standard
form (WSDL), just to see how people might use it.
2. develop a serialization technique that doesn't require redefining
WSDL for each new set of objects (CayenneDataObject may be an ideal
candidate for the "generic object" used in the transport layer). Once
this is in place, current Hessian transport can take advantage of
that as well, removing the ugly requirement to keep client classes on
the server.
3. develop a base for implementation of clients in other languages.
So yes, I agree with your comment that it is wrong for the server to
tell the client what classes to use; however the rest of the
EntityResolver is fine, this is just abstract entity metadata, mostly
platform-independent (ok, the property types are also in Java, guess
we can leave them as is for now, and later remap them as some
"neutral" XMLSchema types or something).
This is just my thoughts, certainly not a roadmap for you. But it
would be nice if you could share your direction as well :-)

Yeah, it's definitely on the radar. Unfortunately, I got wrapped up in the
process of buying a new home and the holiday here didn't help matters too
much.
By the end of this coming weekend, I will have evaluated both Bruno's and
Michael's code contributions. Fortunately, I've been able to still help
them via email, if not via JIRA.
Michael's work is going to take a little more effort on my behalf, since I'm
not all that familiar with the ROP stuff at this point. But, that's fine.
It's gives me an excuse to finally look at it :-) Having said that, if you
have any technical comments to make, it would be welcomed.
