Hi all,
After i configured all files to connect jboss to Mysql Database (i followed this link :
http://docs.jboss.org/jbpm/v5.3/userguide/ch.installer.html#d0e597
http://docs.jboss.org/jbpm/v5.3/userguide/ch.installer.html#d0e597)
After i finished configuring files i'm trying now to run a sampl "Select"
Query.
but i found that there are no ihbernate.cfg.xml file on my folder installation. (normally
it's supposed to be created by install.demo)
Here is my Code lines to run the Query.
Configuration configuration = new Configuration();
SessionFactory sessionFactory = configuration.configure().buildSessionFactory();
Session session = sessionFactory.openSession();
Transaction transaction = session.beginTransaction();
org.hibernate.Query q = session.createQuery("from users");
transaction.commit();

Where are you runing this query? In your app? I think that as jBPM uses JPA you don't
use an hibernate.cfg.xml file, but a persistence.xml.

Thank you so much Demian for your reply.
i can see that jBPM use the JPA but after i run my code it's giving me :
org.hibernate.HibernateException: /hibernate.cfg.xml not found
at org.hibernate.util.ConfigHelper.getResourceAsStream(ConfigHelper.java:170)
....
Can you give me a link where i can found how to use jBPM with Jboss/Hibernate ?

Well, I still don't understand what you are trying to achieve? What do you want to
query?
To create a Query using JPA, you must create an EntityManager from one of the persistence
units you have in persistence.xml.
EntityManagerFactory emf =
Persistence.createEntityManagerFactory("org.jbpm.persistence.jpa");
and then create an entity manager that will let you create a query.
But again, it would be good to know what you are trying to do in order to help you.
Thanks
Demian

Demain,
I have Jbpm5 with jBoss 7 well configured, right now i'm trying to excute a query that
will Insert "a simple row" in my database table "users".
*Here is my code with JPA :*
EntityManagerFactory emf =
Persistence.createEntityManagerFactory("org.jbpm.persistence.jpa");
EntityManager em = emf.createEntityManager();
Query query = em.createQuery("SELECT c FROM users c");
List results = query.getResultList();
System.out.println(results);
When i run this i get this error :
java.lang.IllegalArgumentException: org.hibernate.hql.ast.QuerySyntaxException: users is
not mapped [SELECT c FROM users c]
at
org.hibernate.ejb.AbstractEntityManagerImpl.throwPersistenceException(AbstractEntityManagerImpl.java:601)
at
org.hibernate.ejb.AbstractEntityManagerImpl.createQuery(AbstractEntityManagerImpl.java:96)
at com.sample.ProcessTest.testProcess(ProcessTest.java:46)
at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)
at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source)
at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source)
at java.lang.reflect.Method.invoke(Unknown Source)
...
I'm confused now i'm Using JPA but i get
*org.hibernate.hql.ast.QuerySyntaxException: users is not mapped* Error.
Hope that thinsg get clear for you now.
And i really appreciate your help. Thank you in advance.

Well, there it says that Users is not mapped.
If you want to query the users from task database (
https://github.com/droolsjbpm/jbpm/blob/master/jbpm-human-task/jbpm-human...
https://github.com/droolsjbpm/jbpm/blob/master/jbpm-human-task/jbpm-human...)
you can make "From User"
and when creating the EntityManagerFactory, the persistence unit name is
"org.jbpm.task"
Jbpm uses two persistence units (you can check it in file persistence.xml, it should look
like this
https://github.com/calcacuervo/JBPM5-Samples/blob/master/human-tasks/src/...
https://github.com/calcacuervo/JBPM5-Samples/blob/master/human-tasks/src/...)
One is for human tasks persistence, and the other for jbpm runtime entities.
Hope this helps,
Demian
