[jboss-user] [JBoss jBPM] - LazyInitializationExceptions while using JbpmTemplate (JBPM

[bluesnails]

I have my JbpmTemplate configured correctly in my spring application context and I can inject it into my Spring controllers and other beans, but I am having troubles with LazyInitializationExceptions when using the JbpmTemplate.findProcessInstance(long id) method. 
The test code is like that:
===================
public class TestProcessServiceImpl extends TestCase {

private ApplicationContext applicationContext; 
private JbpmTemplate jbpmTemplate; 

protected void setUp() throws Exception { 
super.setUp(); 
applicationContext = new ClassPathXmlApplicationContext("platform_workflow_ manager_local.xml"); 
out.println("Creating ApplicationContex-------"+applicationContext ); 
jbpmTemplate = (JbpmTemplate)applicationContext.getBean("jbpmTemp late"); 
}

public void testTemplate(){ 
ProcessInstance p =jbpmTemplate.findProcessInstance(1L); 
out.println("======="+p.getId()); 
} 
} 

it throws exceptions:
ERROR [org.hibernate.LazyInitializationException] - <could not initialize proxy - the owning Session was closed> 
org.hibernate.LazyInitializationException: could not initialize proxy - the owning Session was closed 
at org.hibernate.proxy.AbstractLazyInitializer.initia lize(AbstractLazyInitializer.java:60)

at org.jbpm.graph.exe.ProcessInstance$$EnhancerByCGLI B$$5d7ec21a.toString() 
============
And the config files likes:

<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">

<beans default-autowire="no" default-lazy-init="false"

========
Any suggestions why i might be experiencing these errors?

thanks in advance
