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)

the work item handler

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.
