Injecting the hibernate session

[chrisrjcox]

Hi,

I have the following code within a Message Driven Bean, I can get it to create a JbpmContext however I'm getting stuck with regards to Injecting the hibernate session...

Eclipse is stating that I "cannot make a static reference to the none static ethod getCurrentSession() from the type SessionFactory"

I'm following this from Chaper 7 page 5 on the jbpm guide. (7.1.4)

package com.distributed.jbpm.mdb;

import javax.ejb.MessageDriven;
import javax.ejb.ActivationConfigProperty;

import javax.jms.JMSException;
import javax.jms.Message;
import javax.jms.MessageListener;
import javax.jms.TextMessage;

import org.jbpm.JbpmConfiguration;
import org.jbpm.JbpmContext;
import org.jbpm.graph.exe.ProcessInstance;
import org.hibernate.*;



@MessageDriven(activationConfig =
 {
 @ActivationConfigProperty(propertyName="acknowledgeMode", propertyValue = "Auto-acknowledge"),
 @ActivationConfigProperty(propertyName="destinationType", propertyValue="javax.jms.Queue"),
 @ActivationConfigProperty(propertyName="destination", propertyValue="/queue/jbpmQueueTwo")
 })

public class PartTwoMDB implements MessageListener
{
 static JbpmConfiguration jbpmConfiguration = JbpmConfiguration.getInstance();

 public void onMessage(Message inMessage)
 {
 TextMessage textMessage = null;
 try
 {
 if(inMessage instanceof TextMessage)
 {
 textMessage = (TextMessage) inMessage;
 System.out.println("PartTwoMDB: Message received: "+ textMessage.getText());

 JbpmContext jbpmContext = jbpmConfiguration.createJbpmContext();
 System.out.println("PartTwoMDB: jbpmContextCreated");
 try
 {
 jbpmContext.setSession(SessionFactory.getCurrentSession());
 String processDefinitionName = "processTwo";
 System.out.println("PartTwoMDB: processDefinitionName * " + processDefinitionName + " * String created.");
 ProcessInstance processInstance = jbpmContext.newProcessInstance(processDefinitionName);
 System.out.println("PartTwoMDB: Instance" + processInstance.toString() + " Loaded.");
 processInstance.signal();
 System.out.println("PartTwoMDB: Instance signal sent.");
 }
 finally
 {
 jbpmContext.close();
 }

 }
 else
 {
 System.out.println("PartTwoMDB: Message of wrong type: " + inMessage.getClass().getName());
 }
 }
 catch (JMSException e)
 {
 e.printStackTrace();
 }
 catch (Throwable t)
 {
 t.printStackTrace();
 }

 }
}

Could you explain jbpm involvement in this? You do not describe where the error occurs, show no stacktrace, I see nothing in here about injecting a hibernate session, though the subject suggests things in that direction.......

Sorry, I was reading your other post in between while posting this.... I do see the injection going on... maybe there is a typo in 7.1.4 and should it be a little different. Look at hibernate how to retrieve the current session
