<mapping resource="pl/test/jbpm/entity/Persisted.hbm.xml" />
=== Process ==================================
Process from example: Comments
=== API ===================================
ExecutionService executionService = procEngine.getExecutionService();
Map<String, Object> variables = new HashMap<String, Object>();
Persisted p = new Persisted();
p.setName("Variable");
p.setValue("Value");
SessionFactory sf = procEngine.get(SessionFactory.class);
Session sess = sf.openSession();
sess.beginTransaction();
sess.save(p);
sess.flush();
sess.getTransaction().commit();
variables.put("content", "java");
ProcessInstance processInstance = executionService.startProcessInstanceByKey("TaskVariables", variables);
executionService.setVariable(processInstance.getId(), "persistence", p);
=== Stacktrace ==============================
Exception in thread "main" org.hibernate.HibernateException: instance not of expected entity type: org.jbpm.pvm.internal.type.variable.UnpersistableVariable is not a: org.jbpm.pvm.internal.type.Variable

=== Debug logs ==============================
[ScopeInstanceImpl] create variable 'persistence-id' in 'execution[TaskVariables.342]' with value 'pl.test.jbpm.entity.Persisted@970c0e'
=== Problem description =========================
Persistent is a hibernate entity class (configured using XML). The problem is when i'm trying to set hibernate entity as process variable i got exception as above :(
I have no problem to store simple variable as String or Long or even as Serializable class, but for my application i have to store variable as whole entity (in table in DB).
Can You help me with my problem? Did i missed some configuration? Maybe anyone can point complete example of store process variable in DB table ?
Thanks

[Security] - Re: ejb not validating user role at session bean methods + J

I configured my log4j with the details, but did not receive any log of concern..
---------------------------------------------------------------------------------
My login-config.xml snippet is given below
<application-policy name = "SecurityPolicy">
<login-module code = "org.jboss.security.ClientLoginModule" flag = "required">
<module-option name="unauthenticatedIdentity">defaultuser</module-option>
<!-- Any existing security context will be restored on logout -->
<module-option name="restore-login-identity">true</module-option>
</login-module>
<login-module code="com.temp.component.security.LoginCheck" flag = "required">
<module-option name="unauthenticatedIdentity">defaultuser</module-option>
<!-- Any existing security context will be restored on logout -->
<module-option name="restore-login-identity">true</module-option>
</login-module>
</application-policy>
---------------------------------------------------------------------------------
content of the jboss.xml within my ear
<security-domain>java:/jaas/SecurityPolicy</security-domain>
---------------------------------------------------------------------------------
content of the jboss-web.xml in the war file within my ear
<jboss-web>
<security-domain flushOnSessionInvalidation="true">java:/jaas/SecurityPolicy</security-domain>
</jboss-web>
---------------------------------------------------------------------------------
I have defined the role as @RolesAllowed("WRONG_ROLE__FOR_FAILURE") for my ejb session bean method. There is no such role, but still i can access the method..
