I tried to use uuix.hex when I generate id. I am using spring, oracle 9i, hibernate.
I have error when i tried to save new student record into database.
Here is error:
"Object of class [org.alllearn.model.Student] with identifier []: not found "

In oracle, I use trigger that generate id using SYS_GUID()

How can I do it?
