Hi all, I didn't find the bundle with Jboss Portal 2.6.5 + JBoss AS 4.2.2 (Clustered) in download section. So I decided to downloaded JBoss AS 4.2.2 and JBoss Portal 2.6.5 separately, and then follow the "Chapter 2. Installation" from reference guide. At the first time we start it up everything is fine. At any other start up we got the following exception. 15:05:01,000 WARN [arjLoggerI18N] [com.arjuna.ats.arjuna.coordinator.TwoPhaseCoordinator_2] TwoPhaseCoordinator.be foreCompletion - failed for com.arjuna.ats.internal.jta.resources.arjunacore.SynchronizationImple@e441ee java.lang.RuntimeException: at org.jboss.cache.interceptors.TxInterceptor$LocalSynchronizationHandler.beforeCompletion(TxInterceptor.ja va:1182) at org.jboss.cache.interceptors.OrderedSynchronizationHandler.beforeCompletion(OrderedSynchronizationHandle r.java:75) at com.arjuna.ats.internal.jta.resources.arjunacore.SynchronizationImple.beforeCompletion(SynchronizationIm ple.java:114) at com.arjuna.ats.arjuna.coordinator.TwoPhaseCoordinator.beforeCompletion(TwoPhaseCoordinator.java:247) at com.arjuna.ats.arjuna.coordinator.TwoPhaseCoordinator.end(TwoPhaseCoordinator.java:86) at com.arjuna.ats.arjuna.AtomicAction.commit(AtomicAction.java:177) ...
