Creating a non transaction datasource

Question

All,
I am using Quartz to fire Hibernate Jobs. Quartz Scheduler runs as a servlet in tomcat, the Hibernate job is a standalone app.
The Scheduler calls the app like so:
Quartz>Shell>Hibernate.
When I start the Hibernate jobs, they instantly go into a blocked state, basically db dealocks. When view the connections with
mysql admin, I can see the connections are sleep!
I heard thru the grapevine that a non-transactional datasource would solve this problem.
How do I do this? Is it done in tomcat, or do I need to change my hibernate db connection?
Any ideas?

You're deadlocking with another process - quite possibly with one of your earlier tasks that stalled for some reason.
Turning off transactions is a dumb way to fix this - it avoids you finding out what the real problem is, thus curing the symptom but probably not the disease. Find out what's deadlocking and why, then fix that problem properly.
