I did find a work around to this. It seems that any method that referenced the EntityManager had to be in a transaction, and the whole method had to complete before the commits occured. To work around it I removed all references to the EntityManager from my session bean with the timer and set my long running (looping) method so that it doesn't support transactions. I then created another bean that performs the actual database writes. I then called those methods that write to the database from within the long running (looping) method. It seems like a lot of overhead to require this to be done in different beans, but it did work. DaHunter View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4072715#...
