Is there a way to persist a Collection of Objects in Hibernate say,

[code]session.update(Collection Object as arg.)[/code]

Also, is there a way to set a single property in a Collection of Objects by using PropertyAccessor and Setter and other APIs in the package net.sf.hibernate.property and then call the above single line of code and
boom it persists the updated collection.

Pl. let me know.
Thanks a lot for a clue .I tried several things by tweaking but seems Hibenrate doesn't have support , but I may be missing something , so here I am for help in forum.
