Problems retrieving EnityManagerFactory in an stateless EJB Bean

.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ height:90px;width:728px;box-sizing:border-box;
}

I'm having difficulties to persist UserEntitys on my JavaDB from an ejb Project. I tried a couple of solutions from various google searches but non seem to help me.

I'm using GlassFish 4 and the JavaDB which comes with it.

This is my Statlessbean which needs the EntityManager
It should be injected by the container through @PersistenceContext as far as I understand.

@Stateless

public class UserManagementBean implements UserManagementLocal, UserManagementRemote {

    @PersistenceContext(unitName = "ChatDB")

    private EntityManager entityManager;



    @EJB

    private ChatManagementLocal chatManagement;

    @EJB

    private StatisticManagementLocal statisticManagement;



    //...



    @Override

    public void login(String username, String password) throws Exception {

        //...

    }



    @Override

    public void logout(String username) {

        //...

    }



    @Override

    public void registerUser(String username, String password) throws Exception {

        TypedQuery<UserEntity> query = entityManager.createNamedQuery("UserEntity.singleUser", UserEntity.class);

        query.setParameter("username", username);



        UserEntity foundUser;



        try {

            foundUser = query.getSingleResult();

        } catch (NoResultException e) {

            foundUser = new UserEntity();

            foundUser.setLoggedIn(false);

            foundUser.setUsername(username);

            foundUser.setPassword(generateHash(password));



            entityManager.persist(foundUser);

            chatManagement.sendRegisterMessage(username);

        }



        throw new Exception("Der Benutzername ist bereits vergeben.");

    }



    public String generateHash(String password { ... }

}

If it cannot instantiate a JPA provider then either the persistence.xml is not found, or the persistence-unit is not found, or the JPA provider jars are not found. That's all there is

@BillyFrost Where would I check for the exact reason why it failed to retrieve?

– D. McDermott
Nov 22 '18 at 9:03

dont assume "it" will tell you the exact reason. You'll have to inspect your deployment and checks each of those things, and compare with what the docs for that JavaEE server says for use of JPA

So I created this project structure via the Eclipse Project Wizard, is this in general the right place for the .xml files?

Check the spelling of your persistence.xml file. It is incorrect in at least one place above, where it is spelt with ...ance.

I'm having difficulties to persist UserEntitys on my JavaDB from an ejb Project. I tried a couple of solutions from various google searches but non seem to help me.

I'm using GlassFish 4 and the JavaDB which comes with it.

This is my Statlessbean which needs the EntityManager
It should be injected by the container through @PersistenceContext as far as I understand.

@Stateless

public class UserManagementBean implements UserManagementLocal, UserManagementRemote {

    @PersistenceContext(unitName = "ChatDB")

    private EntityManager entityManager;



    @EJB

    private ChatManagementLocal chatManagement;

    @EJB

    private StatisticManagementLocal statisticManagement;



    //...



    @Override

    public void login(String username, String password) throws Exception {

        //...

    }



    @Override

    public void logout(String username) {

        //...

    }



    @Override

    public void registerUser(String username, String password) throws Exception {

        TypedQuery<UserEntity> query = entityManager.createNamedQuery("UserEntity.singleUser", UserEntity.class);

        query.setParameter("username", username);



        UserEntity foundUser;



        try {

            foundUser = query.getSingleResult();

        } catch (NoResultException e) {

            foundUser = new UserEntity();

            foundUser.setLoggedIn(false);

            foundUser.setUsername(username);

            foundUser.setPassword(generateHash(password));



            entityManager.persist(foundUser);

            chatManagement.sendRegisterMessage(username);

        }



        throw new Exception("Der Benutzername ist bereits vergeben.");

    }



    public String generateHash(String password { ... }

}

If it cannot instantiate a JPA provider then either the persistence.xml is not found, or the persistence-unit is not found, or the JPA provider jars are not found. That's all there is

@BillyFrost Where would I check for the exact reason why it failed to retrieve?

Nov 22 '18 at 9:03

dont assume "it" will tell you the exact reason. You'll have to inspect your deployment and checks each of those things, and compare with what the docs for that JavaEE server says for use of JPA

So I created this project structure via the Eclipse Project Wizard, is this in general the right place for the .xml files?

Check the spelling of your persistence.xml file. It is incorrect in at least one place above, where it is spelt with ...ance.

You appear to have mis-spelt "persistence.xml".
