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)

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.
