Question

I am using JPA with hibernate and trying to connect to the a datasource to retrive information but when i run the application i get no error as such but no results are displayed when i run the following code.The question arose from a previous post located here when I was setting up the environment to do some testing of JPA with hibernate on Glassfish.

The log file shows this

INFO: Not binding factory to JNDI, no JNDI name configured

The EJB bean is

@Stateless
public class VMatterDetailsFacade implements VMatterDetailsFacadeLocal {
    public static final Logger log = Logger.getLogger("ejb.VMatterDetailsFacade");

    @PersistenceUnit(unitName = "DBAppPU")
    private EntityManagerFactory emf;    

    private List<VMatterDetails> matterDetailsList;

    protected EntityManager getEntityManager() {
        return emf.createEntityManager();
    }


    @Override
    public VMatterDetails find(String str) {
        throw new UnsupportedOperationException("Not supported yet.");
    }

    @Override
    public List<VMatterDetails> findAll() {
        log.info("Find All Executing");
        matterDetailsList = emf.createEntityManager().createNamedQuery("VMatterDetails.findAll").getResultList();
//        matterDetails.addAll(em2.createNamedQuery("VMatterDetails.findAll").getResultList());
        log.info("Find All Return");
        return matterDetailsList;
    }
    @Override
    public int count() {
        throw new UnsupportedOperationException("Not supported yet.");
    }

and my persistence xml is

<?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.0" xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd">

The log you pasted doesn’t show any ERROR (nor FATAL nor WARNING) message and the particular message you’re showing is just telling you that you didn’t bind the SessionFactory to JNDI. There is nothing wrong with that, many application don’t use a JNDI-bound SessionFactory and this is not really relevant when using JPA anyway. So just ignore this INFOrmational message.

Actually, according to the log file, everything looks fine: your entities have been detected, the named queries processed, the schema has been updated (so the connection to the DB is OK), etc.

That being said, I would first activate SQL logging to see what is happening exactly (this won’t solve the problem but still). You can set either set the following property in your persistence.xml:

<!-- Echo all executed SQL to stdout -->
<property name="hibernate.show_sql" value="true"/>

Or (and I prefer this option because I want fine control over logging anyway), by setting the logging level to debug for the following category:

org.hibernate.SQL

And run the generated SQL against the database.

Second thing, I suggest using an injected container-managed EntityManager instead of using an application managed EntityManager (that’s the preferred way to go in a managed environment):

@Stateless
public class VMatterDetailsFacade implements VMatterDetailsFacadeLocal {
    public static final Logger log = Logger.getLogger("ejb.VMatterDetailsFacade");

    @PersistenceContext(unitName = "DBAppPU")
    private EntityManager em;

    @Override
    public VMatterDetails find(String str) {
        throw new UnsupportedOperationException("Not supported yet.");
    }

    @Override
    public List findAll() {
        log.info("Find All Executing");
        List matterDetailsList = em.createNamedQuery("VMatterDetails.findAll")
            .getResultList();
        log.info("Find All Return");
        return matterDetailsList;
    }
    @Override
    public int count() {
        throw new UnsupportedOperationException("Not supported yet.");
    }
    ...
}

But again, this is just a side note, this won’t solve your problem.

Start with checking the generated SQL and update your question with the result. If the query returns data, please tell us how you checked that the bean method doesn’t work.
