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

And the config files likes:

Any suggestions why i might be experiencing these errors?
thanks in advance
