[JBoss jBPM] - Re: Variables == Bottleneck ?
by gchanteb
Hi all, here is the solution for my problem, based on the other post:
I can now delete properly all ended processes, it works. This should exists by default.
package ****;
|
| import java.util.Date;
| import java.util.List;
|
| import org.hibernate.Query;
| import org.hibernate.Session;
| import org.jboss.ejb3.annotation.Management;
| import org.jboss.ejb3.annotation.Service;
| import org.jbpm.JbpmConfiguration;
| import org.jbpm.JbpmContext;
| import org.jbpm.graph.exe.ProcessInstance;
|
| @Service
| @Management(JbpmManagementMBean.class)
| public class JbpmManagement implements JbpmManagementMBean
| {
| JbpmConfiguration jBPMConfiguration = null;
|
| @SuppressWarnings("unchecked")
| @Override
| public void removeAllEndedProcesses()
| {
| if(jBPMConfiguration==null)
| {
| jBPMConfiguration = JbpmConfiguration.getInstance();
| }
| JbpmContext context = jBPMConfiguration.createJbpmContext();
|
| try
| {
| Session hibernateSession = context.getSession();
|
| Query processQuery = hibernateSession.createQuery(
| "from org.jbpm.graph.exe.ProcessInstance pi " +
| "where pi.end is not null");
|
| List<ProcessInstance> instances = processQuery.list();
|
| if(instances!=null&&instances.size()>0)
| {
| for(ProcessInstance instance : instances)
| {
| context.getGraphSession().deleteProcessInstance(instance);
| }
| }
| }
| finally
| {
| context.close();
| }
| }
|
| @SuppressWarnings("unchecked")
| @Override
| public void removeAllEndedProcessesBefore(Date date)
| {
| if(jBPMConfiguration==null)
| {
| jBPMConfiguration = JbpmConfiguration.getInstance();
| }
| JbpmContext context = jBPMConfiguration.createJbpmContext();
|
| try
| {
| Session hibernateSession = context.getSession();
|
| Query processQuery = hibernateSession.createQuery(
| "from org.jbpm.graph.exe.ProcessInstance pi " +
| "where pi.end is not null" +
| "and pi.start < :removalDate");
|
| processQuery.setParameter("removalDate", date);
|
| List<ProcessInstance> instances = processQuery.list();
|
| if(instances!=null&&instances.size()>0)
| {
| for(ProcessInstance instance : instances)
| {
| context.getGraphSession().deleteProcessInstance(instance);
| }
| }
| }
| finally
| {
| context.close();
| }
| }
| }
package ****;
|
| import java.util.Date;
|
| public interface JbpmManagementMBean
| {
| public abstract void removeAllEndedProcesses();
| public abstract void removeAllEndedProcessesBefore(Date date);
| }
Make a jar and put it in your deploy folder.
