Are you going to cf.Objective (if not, you should!) I will be showing
some new features of ColdSpring that deal with building remote
interfaces for existing services through a proxy factory. It's kind
of like automatic remote services. You can also check the article I
wrote on my blog about using ColdSpring to build remote services here:

with.html
ps. sorry about the spaming, but I am trying to help!

Hello,
I need to expose as web services some of the functionality of an
existing service layer.
Are there any open source frameworks for web services out there
other than Tartan? Or is anyone currently working on such a
product? Or at the very least, does anyone have patterns or
examples that could be useful?
If I had to do it myself, I would be thinking about the following
architecture:
* A collection CFCs that act as method stubs. These live under the
web root and have remote methods. They simply define the arguments
and return value, but call the controller to do the real work.
* A collection of CFCs living under the web root that act as
transfer objects with properties defined by the cfpropterty tag.
These should then be self describing so that clients can know how
to consume our complex objects.
* A controller. I was thinking that this could have one main method
- runService(string:serviceName, struct:arguments):any, or
something - that could be called by the remote methods. This will
allow me to have plugin points for exception handling, request
logging, security, etc.
* Service facade - components that know about the web service
transfer objects and how to get data from the model (calls the
existing model service layer). These would be called by the
controller's runService method.
* ColdSpring to act as a factory for my transfer objects and
service facade components.
