There is system property in cglib "cglib.debugLocation" , if you will set it
cglib will dump classes to this directory, but you will need to modify
hibernate or cglib factories to use "Class.forName".

I figured out my problem I have been using
hibernate.use_reflection_optimizer all this time, only to find out that the
actual property to be set should be
hibernate.cglib.use_reflection_optimizer. Didn't realize it until I printed
out all the properties. Now my buildSessionFactory() time is

Laurent,
With regards to the LEFT JOIN clauses, I've always used mapped Set objects
(many-to-one,one-to-many) and then interated the resulting Java Set object
to return only the objects that I need. I'm sure there's a more efficient
way to do this though, and I'd love to hear what you find out
How would I turn on debug for cglib? looking at the api, it seems like the
method for setDebug can't be accessed outside the package. Is there
something in addition I would have to do to get the class files to be dumped
to the directory? Right now, setting the cglib.debugLocation property

meaning... you can't set this attribute in the Configuration.setProperty()?

Hi,
I would like to have
the query Hibernate of this query sql :
select document.pbl_id from pbl_version_doc
documentleft join reponse on reponse.VPr_ID = document.VPr_IDleft join
reponse_pbl_sit on (reponse_pbl_sit.rps_id = reponse.rps_id and
reponse_pbl_sit.vst_id <> '472a03cb4971e3
so how are you guys bypassing the whole cglib stuff? is it just with that
tiny hibernate.use_reflection_optimizer property? According to my profiler,
more than 60% of Hibernate's startup time is spent creating all the meta
classes for cglib.

hibernate.use_reflection_optimizer is one of those evil "system-level"
properties in Hibernate ... it MUST be specified in hibernate.properties
or with java -D.
(I hate this.)

35 classes. Oh, also disabling the logging provides a good improvement:
LogManager manager = LogManager.getLogManager();
manager.reset();
