Hi all,

I am integrating Jbpm5 with existing application developed using seam2.2.2. With a separate database for jbpm. I created a persisted ksession and it is working correctly. 
Persistence.xml

 <persistence-unit name=+"org.jbpm.persistence.jpa"+ transaction-type=+"JTA"+>
 <provider>org.hibernate.ejb.HibernatePersistence</provider>
 <jta-data-source>java:jdbc/testDS1</jta-data-source>
 <mapping-file>META-INF/JBPMorm.xml</mapping-file>  
  <class>org.jbpm.persistence.processinstance.ProcessInstanceInfo</class>
 <class>org.drools.persistence.info.SessionInfo</class>
 <class>org.drools.persistence.info.WorkItemInfo</class>
 <class>org.jbpm.process.audit.ProcessInstanceLog</class>
 <class>org.jbpm.process.audit.NodeInstanceLog</class>
 <class>org.jbpm.process.audit.VariableInstanceLog</class>
 <properties>
 <property name=+"hibernate.dialect"+ value=+"org.hibernate.dialect.PostgreSQLDialect"+/>  
 <property name=+"hibernate.max_fetch_depth"+ value=+"3"+/>
 <!-- <property name="hibernate.hbm2ddl.auto" value="create"/>    -->
 <property name=+"hibernate.show_sql"+ value=+"false"+ />
 <property name=+"hibernate.format_sql"+ value=+"false"+ /> 
 
 <property name=+"hibernate.transaction.manager_lookup_class"+ value=+"org.hibernate.transaction.JBossTransactionManagerLookup"+ />
 </properties>  
 </persistence-unit>

I needed to access the  processinstance variables to delegate a humane task to another user if the actual user did not complete the task after one hour. I am using a timer to trigger  custom service task registered with a custom workItemHandler. 

My issue : the transaction is canceled after time the timeout (300s) 

WARN [com.arjuna.ats.arjuna.logging.arjLoggerI18N] (Thread-9) [com.arjuna.ats.arjuna.coordinator.TransactionReaper_18] - TransactionReaper::check timeout for TX 7f000101:e18b:4ed4a5a4:10b in state  RUN

my workItemhandler 



*public* *class* SamplelWorkItemHandler *implements* WorkItemHandler {

 *public* *void* executeWorkItem(WorkItem workItem, WorkItemManager workItemManager) {
     
  ProcessInstance processInstance = (ProcessInstance) ProcessManager.+getProcessInstance+(workItem.getProcessInstanceId());
 
 workItemManager.completeWorkItem(workItem.getId(), *null* );
    }

 *public* *void* abortWorkItem(WorkItem workItem, WorkItemManager workItemManager) {

    }
}


 any suggestion ??,

Many thanks.
