I often hear users complaining about the OJB.properties jungle! I really 
like your idea of providing "kits" that contain meaningful default 
settings for different scenarios.

Yes that would be great.

+1. All recent comparisons of OJB and Hibernate I have seen do not 
longer focus on functionality or performance but on documentation!
This is a clear sign that we have to improve in this area!

We already have a sample war target in build.xml that contains a very 
simple servlet app. Maybe this could be a start.

There is also the beer4all application in the contribution package which 
is very easy to setup !

The only problem I see is that HSQLDB jdbc url is not resolved properly 
within the webapp directory structure. Thus the url must be changed by 
hand to contain an absolute path. (see setup instruction of the beer4all 
app) I did not find a solution to get around this problem...
