Greetings everyone! I am recieving a "No active session context" when the timer I have set has timed out. I am running JBoss 4.2 I am using Seam 2.0 Beta (perhaps relevant). The following is the code of interest. If I remove the function (findInvitation) that accesses the database then everything runs ok. I have tried various transaction attribute notation (include using no annotations), but still get the error. Any help is greatly appreciated. Thanks. | @TransactionAttribute(TransactionAttributeType.REQUIRES_NEW) | @Timeout | public void timeout (Timer timer) throws Exception { | Long invitationId = (Long)timer.getInfo(); | //using a dao object to access database. | Invitation invitation = findInvitation (invitationId); | } | The following is the relevant debug output: 2007-07-01 22:07:13,741 DEBUG [org.jboss.ejb.txtimer.TimerImpl] run: [id=1,target=[target=jboss.j2ee:service=EJB3,ear=phoenix.ear,jar=phoenix-security.jar,name=invitationService],remaining=-3,periode=0,active] 2007-07-01 22:07:13,741 DEBUG [org.jboss.ejb.txtimer.TimerImpl] setTimerState: in_timeout 2007-07-01 22:07:13,745 INFO [STDOUT] Pre Checking 21 for cancellation 2007-07-01 22:07:13,747 DEBUG [org.hibernate.impl.SessionImpl] opened session at timestamp: 4847013207027712 2007-07-01 22:07:13,748 DEBUG [org.hibernate.ejb.AbstractEntityManagerImpl] Looking for a JTA transaction to join 2007-07-01 22:07:13,748 DEBUG [org.hibernate.jdbc.JDBCContext] successfully registered Synchronization 2007-07-01 22:07:13,752 DEBUG [org.hibernate.ejb.AbstractEntityManagerImpl] Looking for a JTA transaction to join 2007-07-01 22:07:13,752 DEBUG [org.hibernate.ejb.AbstractEntityManagerImpl] Transaction already joined 2007-07-01 22:07:13,752 DEBUG [org.hibernate.loader.Loader] loading entity: [com.phoenix.security.domain.registration.Invitation#21] 2007-07-01 22:07:13,753 DEBUG [org.hibernate.jdbc.AbstractBatcher] about to open PreparedStatement (open PreparedStatements: 0, globally: 0) 2007-07-01 22:07:13,753 DEBUG [org.hibernate.jdbc.ConnectionManager] opening JDBC connection 2007-07-01 22:07:13,755 DEBUG [org.hibernate.SQL] select invitation0_.id as id0_0_, invitation0_.user_logon as user10_0_0_, invitation0_.template as template0_0_, invitation0_.title as title0_0_, invitation0_.expiration as expiration0_0_, invitation0_.status as status0_0_, invitation0_.email as email0_0_, invitation0_.activation_key as activation7_0_0_, invitation0_.created as created0_0_, invitation0_.last_modified as last9_0_0_ from PHOENIX_INVITATION invitation0_ where invitation0_.id=? 2007-07-01 22:07:13,756 INFO [STDOUT] Hibernate: select invitation0_.id as id0_0_, invitation0_.user_logon as user10_0_0_, invitation0_.template as template0_0_, invitation0_.title as title0_0_, invitation0_.expiration as expiration0_0_, invitation0_.status as status0_0_, invitation0_.email as email0_0_, invitation0_.activation_key as activation7_0_0_, invitation0_.created as created0_0_, invitation0_.last_modified as last9_0_0_ from PHOENIX_INVITATION invitation0_ where invitation0_.id=? 2007-07-01 22:07:13,761 DEBUG [org.hibernate.jdbc.AbstractBatcher] about to open ResultSet (open ResultSets: 0, globally: 0) 2007-07-01 22:07:13,762 DEBUG [org.hibernate.loader.Loader] result row: EntityKey[com.phoenix.security.domain.registration.Invitation#21] 2007-07-01 22:07:13,777 DEBUG [org.hibernate.jdbc.AbstractBatcher] about to close ResultSet (open ResultSets: 1, globally: 1) 2007-07-01 22:07:13,777 DEBUG [org.hibernate.jdbc.AbstractBatcher] about to close PreparedStatement (open PreparedStatements: 1, globally: 1) 2007-07-01 22:07:13,778 DEBUG [org.hibernate.jdbc.ConnectionManager] aggressively releasing JDBC connection 2007-07-01 22:07:13,778 DEBUG [org.hibernate.jdbc.ConnectionManager] releasing JDBC connection [ (open PreparedStatements: 0, globally: 0) (open ResultSets: 0, globally: 0)] 2007-07-01 22:07:13,778 DEBUG [org.hibernate.engine.TwoPhaseLoad] resolving associations for [com.phoenix.security.domain.registration.Invitation#21] 2007-07-01 22:07:13,781 DEBUG [org.jboss.mx.loading.RepositoryClassLoader] setRepository, repository=org.jboss.mx.loading.HeirarchicalLoaderRepository3@6e9e64, cl=org.jboss.mx.loading.HeirarchicalLoaderRepository3$CacheClassLoader@14f1544{ url=null ,addedOrder=0} 2007-07-01 22:07:13,801 DEBUG [org.jboss.ejb3.entity.ManagedEntityManagerFactory] ************** closing entity managersession ************** 2007-07-01 22:07:13,802 ERROR [org.jboss.ejb.txtimer.TimerImpl] Error invoking ejbTimeout: javax.ejb.EJBTransactionRolledbackException: No active session context 2007-07-01 22:07:13,803 DEBUG [org.jboss.ejb.txtimer.TimerImpl] Timer was not registered with Tx, resetting state: [id=1,target=[target=jboss.j2ee:service=EJB3,ear=phoenix.ear,jar=phoenix-security.jar,name=invitationService],remaining=-66,periode=0,in_timeout] 2007-07-01 22:07:13,803 DEBUG [org.jboss.ejb.txtimer.TimerImpl] setTimerState: expired 2007-07-01 22:07:13,803 DEBUG [org.jboss.ejb.txtimer.TimerImpl] killTimer: [id=1,target=[target=jboss.j2ee:service=EJB3,ear=phoenix.ear,jar=phoenix-security.jar,name=invitationService],remaining=-66,periode=0,expired] View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4060582#...
