Howdy,

For the help really appreciate that.
Wanted to ask one more thing is nested transaction possible in Hibernate.
That is can I write code something like this.
public void addCat()throws Exception{
Session session=null;
Transaction tx=null;
Cat cat=new Cat("Scarlet");
cat.addKitten(new Kit
No. Transaction.rollback() does NOT restore the state of the session to
the state prior to Transaction.begin(). You should close the Session after
rolling back a transaction.

Les,
I think you bring up some very good points. While I'll just toss it out as
a nomination, Maven has done a lot of work dealing with these multiple
related project issues. The reactor allows you to build a series of
projects, and sorts out any interdependencies they have. It deals with a

Please stop this discussion. The Hibernate core build process is fine.

In my opinion:
* splitting the tools out of the Hibernate core was the one of the best
things we ever did - it keeps the download small enough and external
dependencies under control (Hibernate was starting to look very bloated)
* Maven looked great until I actually tried to use it and realized

Someone has claimed that this parameter doesn't work if autocommit is
disabled (Hibernate always disables autocommit). I don't know if this is
true or not.

FWIW: At our site we use this parameter in a Tomcat DBCP-resource with
autocommit false if i recall correctly. We have not seen any losses of
database connections.

i'll try looking into it again - but if they have
seperate source
directories without a common root, i'll be sad ;)
Currently every plugin is self contained and has own
source tree. But nothing prevents you to specify
source directory somewhere else ( say, under hibernate

Les,
Sounds interesting, but Java lib directories are getting ever more complex.
Between the Jakarta set of tools and other little pieces that go into making
a large framework tick - you can easily end up with version mismatches.
$APP_HOMEs need consistent usage for them to work.

Ok,
So it seems to me that to use C3P0, you must set the following four
paramaters.
hibernate.c3p0.max_size =maximum connection pool size
hibernate.c3p0.min_size = minimum connection pool size
hibernate.c3p0.timeout = maximum idle time
hibernate.c3p0.max_statements =size of statement cache

Why do we want the dependent JARs out of CVS?

I like your ideas, but plesae do not mix hibernate and hibernateext again.
If you want to improve something - then improve hibernateext build system.
I already has the proposed structure (except avalon plugin which is

Les, you come from a heavy C/C++/make background eh? Env variables are
pretty common in make-land but almost unheard of in java-land.
To restate what Gavin just said as a hard requirement:

Actually, I have a _deep_ foundation in Java with little C++ background.
In fact, I have 3 times more "java
ehlo.
My take on env vars has less to do with make and more of my school of
thought keeping dependency binaries out of CVS. I view CVS as a
_source_ control medium, not a build repository. Env vars are the
logical choice for making clean builds when engaging in that school of
thought.

Restating this more intelligibly.

Proxy equals() defaults to a comparison of identity unless the entity

In the current implementation, it can only break if we have the same
