I have a DB that does not provide Sequences in the same way as Oracle.
Just guessing from your code but it looks like your using Cache. Don't
Cache and EOF do the same thing? IOW, you're building an
object-relational model on top of an object-relational modelling system.
I am using Cache, but only through JDBC as a plug-n-play (almost) replacement
for Oracle or OpenBase or MySQL, etc., depending upon external requirements.
And, yes, in a sense Cache does some of the same things as EOF, but it does
not support WebObjects directly. It may be possible to replace EOF with Cache
Objects, but only by some tricky abstraction of EOEditingContext (et. al.) and
adding the NSKeyValueCoding.DefaultImplementation interface (for WO
compliance) to the Java projection of Cache Objects.
An interesting challenge, but not one I have time, or justification for.
