I'm using JBoss 4.2.3 GA, with jBPM 3.2.6 GA.At first, it worked OK. When I tried to configure the jBPM persistence, I got some errors and exceptions from the DbPersistenceService, related to a Hibernate transaction. Here is a part of the log 2009-05-08 14:38:21,187 DEBUG [org.hibernate.hql.ast.ErrorCounter] throwQueryException() : no errors | 2009-05-08 14:38:21,187 DEBUG [org.hibernate.hql.ast.QueryTranslatorImpl] HQL: | | select pd | from org.jbpm.graph.def.ProcessDefinition as pd | order by pd.name, pd.version desc | | | 2009-05-08 14:38:21,187 DEBUG [org.hibernate.hql.ast.QueryTranslatorImpl] SQL: select processdef0_.ID_ as ID1_4_, processdef0_.NAME_ as NAME3_4_, processdef0_.DESCRIPTION_ as DESCRIPT4_4_, processdef0_.VERSION_ as VERSION5_4_, processdef0_.ISTERMINATIONIMPLICIT_ as ISTERMIN6_4_, processdef0_.STARTSTATE_ as STARTSTATE7_4_ from JBPM_PROCESSDEFINITION processdef0_ order by processdef0_.NAME_, processdef0_.VERSION_ desc | 2009-05-08 14:38:21,187 DEBUG [org.hibernate.hql.ast.ErrorCounter] throwQueryException() : no errors | 2009-05-08 14:38:21,187 DEBUG [org.hibernate.impl.SessionFactoryImpl] Checking 0 named SQL queries | 2009-05-08 14:38:21,187 DEBUG [org.jbpm.persistence.db.DbPersistenceService] creating hibernate session | 2009-05-08 14:38:21,265 DEBUG [org.hibernate.impl.SessionImpl] opened session at timestamp: 5086459908861952 | 2009-05-08 14:38:21,265 DEBUG [org.jbpm.persistence.db.DbPersistenceService] beginning hibernate transaction | 2009-05-08 14:38:21,265 DEBUG [org.hibernate.transaction.JTATransaction] Looking for UserTransaction under: UserTransaction | 2009-05-08 14:38:21,265 DEBUG [org.hibernate.transaction.JTATransaction] Obtained UserTransaction | 2009-05-08 14:38:21,265 DEBUG [org.hibernate.transaction.JTATransaction] begin | 2009-05-08 14:38:21,265 DEBUG [org.hibernate.transaction.JTATransaction] Began a new JTA transaction | 2009-05-08 14:38:21,281 DEBUG [org.hibernate.jdbc.JDBCContext] successfully registered Synchronization | 2009-05-08 14:38:21,281 DEBUG [org.jbpm.persistence.db.DbPersistenceService] begun org.hibernate.transaction.JTATransaction@a15856 | 2009-05-08 14:38:21,281 DEBUG [org.jbpm.JbpmContext] closing jbpmContext org.jbpm.JbpmContext@155aa19 | 2009-05-08 14:38:21,281 DEBUG [org.jbpm.svc.Services] closing service 'persistence': org.jbpm.persistence.db.DbPersistenceService@aea288 | 2009-05-08 14:38:21,281 DEBUG [org.jbpm.persistence.db.DbPersistenceService] committing org.hibernate.transaction.JTATransaction@a15856 | 2009-05-08 14:38:21,281 DEBUG [org.hibernate.transaction.JTATransaction] commit | 2009-05-08 14:38:21,281 DEBUG [org.hibernate.transaction.JTATransaction] Committed JTA UserTransaction | 2009-05-08 14:38:21,281 DEBUG [org.jbpm.persistence.db.DbPersistenceService] closing hibernate session | 2009-05-08 14:38:21,296 DEBUG [org.jbpm.svc.Services] closing service 'persistence': org.jbpm.persistence.db.DbPersistenceService@aea288 | 2009-05-08 14:38:21,296 DEBUG [org.jbpm.persistence.db.DbPersistenceService] committing org.hibernate.transaction.JTATransaction@a15856 | 2009-05-08 14:38:21,296 ERROR [org.jbpm.persistence.db.DbPersistenceService] transaction commit failed | org.hibernate.TransactionException: Transaction not successfully started | at org.hibernate.transaction.JTATransaction.commit(JTATransaction.java:126) | at org.jbpm.persistence.db.DbPersistenceService.commit(DbPersistenceService.java:227) | at org.jbpm.persistence.db.DbPersistenceService.endTransaction(DbPersistenceService.java:132) | at org.jbpm.persistence.db.DbPersistenceService.close(DbPersistenceService.java:198) | at org.jbpm.svc.Services.close(Services.java:243) | at org.jbpm.JbpmContext.close(JbpmContext.java:133) | at org.jbpm.web.BootstrapListener.contextInitialized(BootstrapListener.java:64) | at org.apache.catalina.core.StandardContext.listenerStart(StandardContext.java:3856) | at org.apache.catalina.core.StandardContext.start(StandardContext.java:4361) | at org.apache.catalina.core.ContainerBase.addChildInternal(ContainerBase.java:790) | at org.apache.catalina.core.ContainerBase.addChild(ContainerBase.java:770) | at org.apache.catalina.core.StandardHost.addChild(StandardHost.java:553) | at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) | at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) | at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) | at java.lang.reflect.Method.invoke(Method.java:585) | at org.apache.tomcat.util.modeler.BaseModelMBean.invoke(BaseModelMBean.java:296) | at org.jboss.mx.server.RawDynamicInvoker.invoke(RawDynamicInvoker.java:164) | at org.jboss.mx.server.MBeanServerImpl.invoke(MBeanServerImpl.java:659) | at org.apache.catalina.core.StandardContext.init(StandardContext.java:5312) | at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) | at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) | at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) | at java.lang.reflect.Method.invoke(Method.java:585) it continues for a lot of lines below....
