Hello there, i'm using hibernate, from the company sample, every one busy so they cant answer me, also newly it's 14 day vacation... though i'm still working, i cant see any one to take help from...

the problem i have , is to join multiple data, i'm not much familiar to Hibernate, and using old data model from last system...
the problem i facing, is if i do catch data, and start joining 2 table inside my java classes, the speed will decrease to much that it take several minutes just for one single process...

i wanna join my data model and if is possible, recieve only list of objects...

Also i prefer to use:
class ... extents HibernateDaoSupport
...
HibernateTemplate hibernateTemplate = getHibernateTemplate();

because all my old model are based on that, but the look i had over internet network, there are many ways to do this, but i'm more familar with this one, and i already done providing my bean files, i dont wanna define beans for repeatedly models again...

also i dont wanna move to new Hibernate type of definition, becasue i already done half of the projects...

i also saw some days ago, that user used session to get list of objects, but if using hibernate template its not possible, any other answer will help me...

Thank you
for your attention, precious time and your patient.
