Okay, so it seems that injection doesn't work in anything other than session beans (that means not in Web Services or MBeans) according to this thread: http://www.jboss.com/index.html?module=bb&op=viewtopic&t=107353 So at least I know I should stop looking for why injection doesn't work in 4.2.2GA. But if I try to use the same mechanism I used in the Web Service in my schedulable, I get errors because I can't get a UserTransaction. I *must* have a transaction to use the EntityManager. So how do I get a transaction? Or do I need to stop using the EntityManager with my schedulable? If so, how do I get to my EJBs and Entity Beans?
