Hi Joe, If you are using Oracle (which would be my guess, based on your email domain), then you can simply create an Oracle Synonym for the Sequence that the WebObjects app uses.
Basically it's an alias so when you ask for the Synonym, you'll get the thing it points at. That should allow you to mess with the DB behind EOF's back. You traitorous heathen. :-) Just be mindful that depending on how you are fetching data in the WebObjects app, you may or may not immediately see the new information in the WO app that you've inserted with Cayenne.
