As I see it, in WO, I can either choose between a Java Client

Additional you can use WebServices to communicate with a Cocoa
application. Be prepared to have a lot of traffic between the app
and the server when you have long lists or big objects. Also you will
run into a good bunch of optimistic looking failures when a couple of
users work on the same data.
Perhaps AJAX may a not soo bad idea to get the interactivity to the
user and the direct connection to the server.
It all depends on your problem and the typical usage patterns. I have
learned in the past that users are happy with a simple web interface
if it works as expected.
Or, to put it in other words: I've read that WO is the technology
behind the iTunes Music Store. The iTunes application itself is
pure Cocoa, I guess. But what is actually connecting the two?
XML. Not sure whether it's a WebService (SOAP).
Keep in mind: asynchronous work on shared data by a couple of users
on large dataset and a Cocoa app displaying/editing the data will:
- give you HEAVY network traffic,
- drive you into a lot of locking handling,
- makes the whole dev process much more complex,
- make you mad because you have to handle a lot of WebObjects AND a
lot of Cocoa problems.
