Hi jits_1998, As an example, my principal custom object has, amongst its fields, a long that is an id of a jbpm process instance. This custom object is saved in DB by Hibernate through a regular session while the jbpm process instance is saved using a jbpmcontext. The hib. session is obtained from the same configuration as jbpm, for having the (few) tables in the same schema is not an issue. | public static Session createPersistantSession() { | DbPersistenceServiceFactory dbPersistenceServiceFactory = (DbPersistenceServiceFactory) instanceConfigurationJbpm.getServiceFactory("persistence"); | return dbPersistenceServiceFactory.getSessionFactory().openSession() ; | } | Right now, the issue in the post above is not anymore but I am facing a new one about contexts closed more than once I'm using version 3.2 | 11:11:03,653 [Thread-3] ERROR DbPersistenceService : problem rolling back after failed commit | org.hibernate.TransactionException: Transaction not successfully started | at org.hibernate.transaction.JDBCTransaction.rollback(JDBCTransaction.java:149) | at org.jbpm.persistence.db.DbPersistenceService.close(DbPersistenceService.java:166) | at org.jbpm.svc.Services.close(Services.java:211) | at org.jbpm.JbpmContext.close(JbpmContext.java:139) | at com.aspheria.cerbere.Workflow.run(Workflow.java:515) | at java.lang.Thread.run(Thread.java:534) | 11:11:03,653 [Thread-3] ERROR Services : problem closing service 'persistence' | org.jbpm.persistence.JbpmPersistenceException: couldn't commit hibernate session | at org.jbpm.persistence.db.DbPersistenceService.close(DbPersistenceService.java:172) | at org.jbpm.svc.Services.close(Services.java:211) | at org.jbpm.JbpmContext.close(JbpmContext.java:139) | at com.xxxx.cerbere.Workflow.run(Workflow.java:515) | at java.lang.Thread.run(Thread.java:534) | Caused by: org.hibernate.TransactionException: Transaction not successfully started | at org.hibernate.transaction.JDBCTransaction.commit(JDBCTransaction.java:100) | at org.jbpm.persistence.db.DbPersistenceService.close(DbPersistenceService.java:162) | ... 4 more | | ... 4 more | org.jbpm.JbpmException: closed JbpmContext more then once... check your try-finally's around JbpmContexts blocks | at org.jbpm.JbpmConfiguration.popJbpmContext(JbpmConfiguration.java:521) | at org.jbpm.JbpmConfiguration.jbpmContextClosed(JbpmConfiguration.java:537) | at org.jbpm.JbpmContext.close(JbpmContext.java:144) | at com.xxxx.cerbere.Workflow.run(Workflow.java:515) | at java.lang.Thread.run(Thread.java:534) | Thanks for your help JBaton View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3970957#...
