When my http session times out (it is 60 min long) and I log in again in my application I get this exception for every EJB Stateful: anonymous wrote : Could not activate; failed to recover session (session has been probably removed by session-timeout) I've already tried to adjust some configuration parameters in standard-jboss.xml like max-bean-age (inactivity time before to passivate) and max-bean-life (inactivity time before to remove) but without success. I repeat that the problem occurs just for stateful ejb, not stateless. Please help me, otherwise my customer will return to use Weblogic ;-) Thanks in advance, Costantino Cerbo View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4059608#...
