I just found an interesting quote from a paper on JDO:
http://www.jdocentral.com/pdf/eigner_jdo.pdf
"With the availability of JDO, it makes you wonder when and if you would ever need an EJB container at all within your application architecture if you use it only as a front-end to your database. All the model-oriented business logic can be
coded in the classes persisted by JDO, sparing us from using patterns such as 'data object' or 'value object'. After using JDO we contend that most web-based applications could be developed more easily with a web container and a set of JDO enhanced classes to encapsulate the model of the application. "
This sounds very attractive to me from a learning POV for a standard DB application: * use flow for the controller; interactiing with forms and * enhanced JDO for the model/data access * views by generator of your choice...

Thanks - I assume that if one is NOT working in a J2EE application, that the principles and approaches will be the same ie. is there more info that discusses how to move from an "ordinary" set of Java objects to a full-blown J2EE approach?
It's quite difficult to say what constitutes a "full-blown" J2EE app versus an "ordinary" Java app, to use your terms. J2EE is made up of many technologies, not all of which must be used together at any one
time.
Cocoon typically runs inside a Servlet container, whose behavior is mandated by the J2EE spec, so when you're running "cocoon servlet",
yes, you have a J2EE application. Even if you don't use EJB, JTA, JMS, etc.
But if you want to know what a "typical" J2EE app looks like, I think the patterns book that was mentioned in this thread (a possibly also this one [1]) might give you a bigger picture.
