To all, I am using Win XP and JBoss 4.0.4 GA; I am following the instructions on chp 04 of the "Getting started with JBoss 4 release 5"; however when I tried to deploy the JBossDukeBank.ear to JBoss, I got numerous deployment errors / warnings. 14:19:08,993 WARN [StatefulSessionContainer] Could not restore ejb timers RuntimeMBeanException: null Cause: java.lang.NullPointerException ... I'm not sure what's wrong, but looks sth might not be configured correctly beforehand, but the guide didn't say much on pre-configurations.... Any ideas?
