问题


I recently changed my JPA design for that :

persistence.xml

<?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">
    <persistence-unit name="flightfaq" transaction-type="JTA">
        <provider>org.hibernate.ejb.HibernatePersistence</provider>
        <properties>
            <property name="hibernate.archive.autodetection" value="class, hbm" />
            <property name="hibernate.connection.username" value="root" />
            <property name="hibernate.connection.password" value="password" />
            <property name="hibernate.connection.url" value="jdbc:mysql://localhost:3306/flightfaq" />
            <property name="hibernate.connection.driver_class" value="com.mysql.jdbc.Driver" />
            <property name="hibernate.hbm2ddl.auto" value="update" />
            <property name="hibernate.c3p0.min_size" value="5" />
            <property name="hibernate.c3p0.max_size" value="20" />
            <property name="hibernate.c3p0.timeout" value="300" />
            <property name="hibernate.c3p0.max_statements" value="50" />
            <property name="hibernate.c3p0.idle_test_period" value="3000" />
            <property name="hibernate.show_sql" value="true" />
            <property name="hibernate.format_sql" value="true" />
            <property name="hibernate.dialect" value="org.hibernate.dialect.MySQLInnoDBDialect"/>
            <property name="use_sql_comments" value="true" />
            <property name="jadira.usertype.autoRegisterUserTypes"
                value="true" />
        </properties>
    </persistence-unit>
</persistence>

Dao's

@Singleton
@LocalBean
@Startup
public class AircraftTypeDaoImpl implements AircraftTypeDao {

    @PersistenceContext
    private EntityManager em;

    /** JPQL query to find a {@link AircraftType} given its OACI name */
    private static final String JPQL_FIND_BY_TYPE = "SELECT a FROM AircraftType a WHERE a.typeOACI=:typeOACI";

    /** JPQL query to find all {@link AircraftType} */
    private static final String JPQL_FIND_ALL = "SELECT a FROM AircraftType a";

    public AircraftType find(String typeOACI) throws DAOException {
        AircraftType aircraftType = null;
        Query findQuery = em.createQuery(JPQL_FIND_BY_TYPE).setParameter(
                "typeOACI", typeOACI);
        aircraftType = (AircraftType) findQuery.getSingleResult();
        return aircraftType;
    }

    @SuppressWarnings("unchecked")
    public List<AircraftType> findAll() throws DAOException {
        return em.createQuery("SELECT a FROM AircraftType a").getResultList();
    }

}

managed bean simplified

@ManagedBean
@ViewScoped
public class MissionHandler implements Serializable {

    private static final long serialVersionUID = 2462652101518266609L;

    private Mission mission;

    private List<FlightFeasibilityException> exceptions;

    @EJB
    private AircraftTypeDaoImpl aircraftTypeDao;

    public MissionHandler() {
    }

    @PostConstruct
    public void init() {
        /** Create an empty mission */
        mission = new Mission();
        /** Create an empty list of exceptions */
        exceptions = new ArrayList<FlightFeasibilityException>();
        /** get aircraft types from the database */
        aircraftTypes = aircraftTypeDao.findAll();
        System.out.println("dump types");
        for (AircraftType type : aircraftTypes) {
            System.out.println(type.getTypeOACI());
        }
        System.out.println("init done");
    }

}

Contrary to my other post, the web server loads perfectly. (I´m closing the other one, I don't know what happend) But in the @PostConstruct method of my managed bean (which is called direclty when loading the first xhtml page of the app) the aircraftTypes list is empty ! I know the JPQL query is OK because it´s fairly simple and it works before this design change. My guess is that the created entitymanager is not querying on my "flightfaq" database. I really don't understand, since I have one persistence-unit only.

Below is the log displayed by TomEE on launch You will see the hibernate log when querying aircraft Types, but nothing just after, when printing the list's content

回答1:


Have you tried providing the explicit name for persistence unit? I was told once that it is always best to provide the name even if you only have one by David Blevins, one of the devs of TomEE ;-)

Though I actually doubt that it will solve your problem.

By the way, if you change the creating of the queries to adding the class of the result type, you can leave out the cast

em.createQuery("SELECT a FROM AircraftType a", AircraftType.class).getResultList();

These methods always return TypedQuery<AircraftType>

Then you can the avoid warning message.




回答2:


I found the problem. It was related to my TomEE Web server configuration. I needed to describe my dataSource in tomee.xml file (which I did) AND copy these definitions in the openejb.xml file that is deployed in the hard disk directory where TomEE deploys the webapps and other stuffs. I thought this copy was done automatically (from tomee.xml to openejb.xml)

Everything is well detailed in this thread

Note that the behaviour is now as expected using :

  • @ ManagedBean / @ ViewScoped
  • @ Singleton / @ Startup / @ LocalBean
