Best of luck ;-) As far as the anonymous wrote : | Can anybody tell me in what kind of security and transaction context the work thread will run? | The answer is that it will be unspecified being that the WorkManager API is meant to be consumed solely from a ResourceAdapter which would have it's own transaction/security context. In other words, it is unknown and there are no guarantees because this is a non standard use of the API. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4008852#...
