I am running into problems with slow performance. Is there a way to load only objects needed for each request?

I have created 160 hbm.xml files for each table and during each time I execute session it initializes all objects even though I only use a few of the tables. Is there a way to load only the tables I will use and not all of them? That should speed up the load up time.

Did you try setting the "class" attributes lazy parameter to true or false.

I was just reading on that now. Should it be done like this for all classes?
<class name="rapidReview.core.hibernate.PrJournalRoleInfo" table="PR_JOURNAL_ROLE_INFO" schema="AACR20_DBA" lazy="false">

Yup! Think that should help. If it is still is slow, then I would see if you can cache it and load all info once and be done with loading.
