Hi all!

I'm a newbie to JBoss and have a question nobody
asked. I'm calling a setter method of my entity
bean. Instead of only updating the corresponding
table's column JBoss deletes/inserts a whole row in
one transaction. Is it default JBoss behavior?
Can I set some options in config files to change this
behavior? If not what does 'tuned-updates' option in jaws.xml exactly mean?
I use JBoss-2.4.4 and Hypersonic SQL database.
Thank you in advance.
