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.
