How much back-wards compability should there be for hibernate-1.1 dtd in
hbm2java ?
(Here thinking on the recent 'role to name' name change)...
Just wanting to hear the general opinion ?
(Im +1 on having hbm2java only support hibernate-2.0.dtd)

Hi all,
I have a problem with hibernate and postgresql that I suspect might be
related to Matt Raible's Oracle problems. Every time hibernate does
it's stuff to update the database, postgres spawns another "idle in
transaction" process. Eventually it gives up and the driver throws: -
Backend star
Im approx +0 on this one :)
Gavin, why was this done in the first place ? Seem to remember somewhere
that the docs states:
Free from my mind: "Hibernate does not hide what's happening. e.g.
SQLExceptions is propagated all the way up to the user." .

And so it begins - I eliminated about 100 lines of code by passing in a List
of longs, vs. a List of objects with their id's set. Thank you from the

We havn't actually had much discussion of middlegen on

recent burst of activity is mainly in response to the

That "unexpected EOF" usually occurs if somehow the connection
between client and database processes is broken (eg. the

of hi/lo generation? (And remember that you can't use

I'm having troubles getting my objects to persist. In my pgsql.err, i get

Sorry, thats nowhere near enough information. You should

That would have been your problem. You *must* make sure that
ALL DAOs are using the same Session instance. (And
SessionFactory _should_ certainly be a singleton.)

I am using the following method to get back a list of objects based on ids.
What I would prefer is to get back a list of objects sorted by object.name.
I know there's an easier way to do this with hibernate, but I can't seem to
find it.
