DbPersistenceServiceFactory should not close SessionFactory if it did not open it --------------------------------------------------------------------------------- Key: JBPM-2605 URL: https://jira.jboss.org/browse/JBPM-2605 Project: jBPM Issue Type: Bug Security Level: Public(Everyone can see) Components: Runtime Engine Affects Versions: jBPM 3.2.7 Environment: JBoss 4.2.3, Seam 2.1 Reporter: Stefano Travelli Assignee: Alejandro Guizar Priority: Critical Fix For: jBPM 3.2.10 Original Estimate: 0 minutes Remaining Estimate: 0 minutes I configure JBpm with Seam 2.1 so that the JBpm SessionFactory is the same of the underlying SessionFactory used by the EntityManagerFactory in JPA. In order to do so I include JBpm hibernate.cfg.xml in the persistence-unit. Then I declare the JNDI name in jbpm.cfg.xml: <persistence-unit name="getin"> <provider>org.hibernate.ejb.HibernatePersistence</provider> <jta-data-source>java:/getinDS</jta-data-source> <propertyies> <!--- ... ---> <property name="hibernate.session_factory_name" value="java:/getinSessionFactory"/> <property name="hibernate.ejb.cfgfile" value="jbpm.hibernate.cfg.xml"/> </properties> </persistence-unit> <jbpm-configuration> <jbpm-context> <service name="persistence"> <factory> <bean class="org.jbpm.persistence.db.DbPersistenceServiceFactory"> <field name="isTransactionEnabled"> <false/> </field> <field name="sessionFactoryJndiName"> <string value="java:/getinSessionFactory"/> </field> </bean> </factory> </service> <service name="tx" factory="org.jbpm.tx.TxServiceFactory"/> <service name="message" factory="org.jbpm.msg.db.DbMessageServiceFactory"/> <service name="scheduler" factory="org.jbpm.scheduler.db.DbSchedulerServiceFactory"/> <service name="logging" factory="org.jbpm.logging.db.DbLoggingServiceFactory"/> <service name="authentication" factory="org.jbpm.security.authentication.DefaultAuthenticationServiceFactory"/> </jbpm-context> </jbpm-configuration> It works fine except that during test execution in the Seam enviroment JBpm context is opened and closed several times while the persistence unit stays. However, as a JBpm context closes, DbPersistenceServiceFactory also closes the SessionFactory invalidating the EntityManagerFactory. When DbPersistenceServiceFactory doesn't create the SessionFactory taking it from JNDI, it shouldn't close it as this should be a responsibility of the component who registered it in JNDI in first place. The patch is simple: public void close() { if (sessionFactory != null && sessionFactoryJndiName == null) { log.debug("closing hibernate session factory"); sessionFactory.close(); } }
