i don't know enough about any of this stuff to comment. it may be that
my database package
is just that... a database persistence package. ejb3 sounds larger than
"database".

If you are writing a small ejb3 app that is not separated by layers ( I
don’t want to fume the flamewar) you would create and initialize the
entitymanagerfactory in your application object and create entity managers
using that. This is the way to access entitymanager if you are not using the
rest of the container.
In a bigger app you would inject your session beans into wicket application
using jndi and gain access through them.

I don't think you are disagreeing because I agree with both of you.
There's something in the Java water that just leads to overly
abstracted software... I fall for it from time to time even
though I'm
getting better at seeing it.
Back on topic a bit, Jonathan, I looked at your database
package and I
like what you have there. I was wondering how you see EJB3 and
Hibernate fitting together in your wicket-contrib-data
package. Are you
working with pre-3.0 Hibernate? My understanding is that the ejb3
version would have an EntityManager injected into the code by the
container instead of the session object. Are you planning on
creating a
new
wicket.contrib.database.ejb3 package or would this still be
considered
Hibernate?
i'm using hib3 but not entity manager. i don't know yet how
that would work.
I guess in a nutshell, what I'm asking is, "If I want to make an
annotated Hibernate 3/Ejb3 version of your database package,
should I
write a new package in the same structure as the one you wrote or is
yours going to encompass that?"
good q. don't have time to learn ejb3 right now. maybe you
will have opinions on that soon...
feel free to contribute!

I just realized this is another thread that should probably
be on the
dev mailing list.

nothing's perfect. i'm not talking about perfect. that's
religion.
i'm just talking about
things where people bothered to work problems until the solution was
not
only workable
but just reasonably good and simple. there are so very few
things like
this given the billions and billions and billions of dollars
that have
been pumped into
software.

I agree on the interface issue, but I also think you put it

when you say it is just the fads that say this. Software
engineering
is still an immature industry, so we have to look for right
principles
and best practices to get us to the next step. The Abstract
Class vs
Interface is pretty controversial (though again, I'm all on your
side), but having 'interface based design', can save you
from designs
that aren't as good. I guess just as AOP can save you from
less than
perfect designs. And lets be honest, a perfect design is
really hard
to get, and Wicket surely is not perfect yet either. And OO
as put in
Java is not nescesarily the end of the road either.

this rant isn't in response to you or anyone on this

venting....
one of the many reasons i'm so sick of software lately is
that nobody
ever takes the
time to think things through. that's why we've got all
these stupid
industry fads and buzzwords and people naming classes
"EntityBaseImplDelegate".
there is a time and a place for abstraction and flexibility.
everything should not
be malleable. everything should not be named abstractly.
EVERYTHING
SHOULD
NOT BE AN INTERFACE! is anyone out there listening to
me!? and the
latest buzzword should not be in every project. trying to blindly
apply design patterns, interfaces and fancy abstractions is not
always a sign of mature design. in fact, it's often quite the
opposite! i'm reminded of this quote:
