Hi, after a few difficulties in setting the configuration for PersistenceBroker API (read access) and ODMG (write access) with Tomcat's datasource I still feel unconfortable in access a DB from struts actions with OJB. Is there a best practice available with all exceptions etc.?
There is an excellent O'Reilly book on Struts programming by Chuck Cavaness. It contains a whole chapter on using STruts and OJB.
Chuck also provides Powerpoints slides on STruts and OJB and even a tutorial site.
All available from our "further readings" section:
http://db.apache.org/ojb/links.html

Why are special DB tables necessary for ODMG??
because ODMG spec requires support for persistent collections.
So to store for instance an ODMG DList, we need tables to hold those datastructures.
