Thanks for the advice. This parameter is set in C:\db-ojb-1.0.rc1\target\test\ojb\repository_database.xml, right? Do I need to change anything else to modify this behavior?
I'm still trying to feel my way around this system. Basically, I have about a week to make a recommendation on using it, in a large project. Ease of use is an important consideration, especially to the powers-that-be who are managing this project.
I understand the managements concerns. I'm working in a management heavy company...
I know from projects that I have been coaching that OJB has definitely a learning curve. This is a fact that may not be visible at first sight.
But OJB (and any other full blown O/R mapping tool) deals with so many complex problems that it will take some time to get familiar with all bells and whistles.
An O/R tool frees the developers from manually coding several abstract application layers. Martin Fowlers latest book "Patterns of Enterprise Application Architecture" (must have reading!) dedicates several chapters on all issues of Mapping Object-oriented applications to relational databases. Many of the patterns he presents are implemented in OJB.
To benefit most from OJB it is crucial to be familar with the design principles, patterns and strategies behind it.
Developers that are used to full fledged commercial O/R tools like TopLink do not find it hard to switch to OJB. (The main difference is the price tag :->)
But developers that are not familiar with O/R tools will need some training or extra time for learning.
I don't want to discourage you, but I think that it is important to frankly tell the management that your team will need additional training if they are not used to other O/R tools already.
And this is *not* and OJB specific problem! Good readings: - Fowlers "Patterns of Enterprise Application Architecture" - books mentioned on this page: http://db.apache.org/ojb/links.html
cheers, Thomas

Seems a problem with the used sequence manager (SequenceManagerHighLowImpl). Try to run the test cases with SequenceManagerInMemoryImpl Do you get the same results?
