Hi I'm writing an application that processes a huge amount of data. I want to kick this off in the middle of the night with a timer service inside of the app server so that the slsb can chew on the problem set for a few hours and shove data into the database when needed. Now, the issue is the transaction times out. It's a bad idea to extend the transaction timeout to hours, so I figured I would bracket the database work by opening and closing the transaction (since I know where the delimiters are). Ok, so Seam isn't letting me do things like: | while(moreDataToProcess) { | someProcessing(); | | entityManager.getTransaction().begin(); | ... | entityManager.persist(obj); | entityManager.getTransaction().commit(); | | otherProcessing(); | } | giving an error of: ERROR [org.jboss.ejb.txtimer.TimerImpl] Error invoking ejbTimeout: javax.ejb.EJBException: java.lang.IllegalStateException: Illegal to call this method from injected, managed EntityManage There must be a way to tell Seam to quick trying to control the transaction inside of a particular slsb (or for the whole app server) - but for the life of me I can't find documentation or posts on how to do that. Any pointers to docs or posts, or comments on how to approach this? Thanks, Greg View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4030369#...
