I was wondering, how usable is the Hibernate2 codebase right now?
Obviously I'm not looking to rush it into production, but I have a
project that would be a suitable guinea pig if Hib2 compiles and
(mostly) works...
Thanks,
Jeff

Yes, I'm glad you raised this Ara, there are a couple of different
things I've been speculating about here:
(1) An isDirty() interceptor callback, to allow an application to
implement its own dirty checking algorithm
(2) A new property attribute; update="never|auto", to declare
"readonly"
What about a isModified()? For tracking modification. Is it possible to
add a modification-tracking="true" to a and let Hibernate
decide whether an object is modified (a setter method actually changed a
property, etc) and then only update that modified object and that
specific field only?
Ara.
Yes, I am very open to this; not only for instantiation, but
also for *proxy* instantiation. My motivation for this is
integration with AOP frameworks.
How I propose to do this is to add some more methods to
Interceptor in Hibernate2. (It is currently possible by
extending EntityPersister, but tha

So is it possible to get a parent w/ children and only make a call to
update(parent)? From your e-mail below, I gathered that I could change
my storeObject() method to use update() rather than saveOrUpdate() and
everything would work peachy-keen. Nope, I still get the same error -

Just a quick query: as I understand it, each Object that uses Hibernate
for persistence needs to have a concrete class with an empty
constructor. How hard would it be to modify Hibernate to call a method
on a factory class instead of "new"? And how hard would it be to be

If anyone can point me to an example of what is expected for this

Its perfectly possible to let the object decide with this new
functionality;
just define an interface with an isPersistent() method thats implemented
by the persistent classes. Let the interceptor call that method, if the
passed object implements the interface, otherwise return null and

Since I seem to be spending *so* much time with problems relating
to saveOrUpdate() functionality, I decided to provide some new
functionality.
The Hibernate2 interceptor interface now has a
Boolean isUnsaved(Object)
method, so that the application can use something completely
different to unsav
I suppose I'm overstating this case a little. I guess it might be
slightly helpful when deploying to a staging server with "live"
data. But I still don't see it really working in practice.

Yes, which is problematic if you plan to use a common Hibernate
architecture
where the actual data model objects are exposed to the User Interface,
even in a three-tiered application. True transparent persistence lets you
do this in a philosophically pleasing way.

But hey! thats only half the story! Also: Don't hit the database

A persistence layer "backed up" by the all and mighty Martin Fowler :)

Almost forgot a "hidden" fact :)
It does not seem Jaxor supports "transparent" persistence - e.g. the beans
need to be somewhat specieal and provide methods for the persistencelayer to

example can be found at:

Hi, guys
I am currently designing a Java project. I'd like to

Don't use toplevel collections because we have removed them from 2.0.
(Your use case is correct, however.)

Of course!
Its a FAQ item that assigned ids including composite ids can't distinguish
between a
saved or unsaved object (you have a choice between "always update" or
"always insert").
So if you want to add a new child (with unsaved-value="none"), simply save
() it
manually first:
