[jbpm-issues] [JBoss JIRA] Commented: (JBPM-1307) jBPM tries to use Hibernate transaction even if configured with isTransactionEnabled = false

jBPM tries to use Hibernate transaction even if configured with isTransactionEnabled = false -------------------------------------------------------------------------------------------- Key: JBPM-1307 URL: https://jira.jboss.org/jira/browse/JBPM-1307 Project: JBoss jBPM Issue Type: Bug Security Level: Public(Everyone can see) Components: Core Engine Affects Versions: jBPM 3.2.2 Reporter: Mauro Molinari Assignee: Alejandro Guizar The method org.jbpm.scheduler.db.DbSchedulerService.deleteTimersByProcessInstance(ProcessInstance) is accessing the Hibernate transaction even if jBPM is configured not to use transactions: <service name="persistence"> <factory> <bean class="org.jbpm.persistence.db.DbPersistenceServiceFactory"> <field name="isTransactionEnabled"> <false /> </field> <field name="isCurrentSessionEnabled"> <true /> </field> </bean> </factory> </service> This causes a serious problem when you're using jBPM inside a JTA environment and you want to control JTA transactions by yourself. For instance, we're using Spring to manage transactions a JBoss Transactions as the JTA implementation. We are not using JNDI in any way, but when we try to call processInstance.end(), a call to org.jbpm.scheduler.db.DbSchedulerService.deleteTimersByProcessInstance(ProcessInstance) is performed and Hibernate tries to create a new JTATransaction by querying an empty JNDI InitialContext. The only workaround we could find is the one outlined here: http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4117325#... that is, subclassing JobSession in order to use Spring TransactionSynchronizationManager.
