Transition from EOF to Cayenne
We are looking to consolidate our code bases between our Cayenne based web
services and our WebObjects/EOF based applications. Has anyone written any
transition classes or notes of things that they did to help the code
porting? We have 2 separate models but we need to deal with NSArrays,
NSData, DisplayGroups, etc. We use Eclipse so making mass changes isn¹t too
scary. Any thoughts or guidelines would be very helpful. We are not ready to
replace our WebObjects components yet that is another project.

Not sure when we are going to start this effort in earnest. I think probably
sometime in Q1 next year. I will at least keep some notes and send them
along.

I recall others were doing something like that. Unfortunately nothing
has been contributed to the community that can be reused. Would be
nice if we can do it this time. Dov, if you come up with some kind of
portability layer, do you think it would be possible to contribute it
to Apache, or at least document the experience on Wiki?

If the EOModel has custom types, it won't import into Cayenne Modeler.

It was mostly just a find-and-replace session when I did it four?
years ago. I converted everything, though -- I didn't convert only
the EOF part.
For the EOF part, it was an easy transition. Load the model into the
Cayenne model and save it out again. For java, change the class and
method names names and delete the .lock() statements :-)
The biggest pain was switching between NSDictionary and Map: the
arguments are reversed for the put() method.

If you search the Cayenne mailing lists (use any search field on the
ObjectStyle web site, such as on
http://incubator.apache.org/cayenne/index.html) and search for
NSArray, you'll probably find some information on the subject (I know
others have used Cayenne with WebObjects).
