The following code seems to throw a NullPointerException at the QuestionRepository class, but I don't managed to fix it. I don't know if I have done anything wrong with the context dependency injection?
Entity
#Entity
#NamedQueries({
#NamedQuery(name=Question.ALL, query="SELECT q FROM Question q")
})
public class Question implements Serializable {
private static final long serialVersionUID = 2402027045394206281L;
public static final String ALL = "Question.all";
Repository
#Named
public class QuestionRepository {
#PersistenceContext(unitName="SertifikatPU")
private EntityManager entityManager;
public List<Question> all() {
TypedQuery<Question> query = entityManager.createNamedQuery(Question.ALL, Question.class);
return query.getResultList();
}
}
EJB
#Local(QuestionLocal.class)

Project structure:
Try to merge the projects in one. Maybe there is a bug in the frameworks when more than one project is used.
Your problem is located at your class QuestionRepository.
If I've read it right, this is a simple class, not a server managed class. What does it mean? It means that due that this cause, this piece of code
#PersistenceContext(unitName="SertifikatPU")
private EntityManager entityManager;
does nothing because the class is instanced by you, nor by the server, so the persistence context is unknown from the point of view of the class. The consequence is that at this other piece of code
public List<Question> all() {
TypedQuery<Question> query = entityManager.createNamedQuery(Question.ALL, Question.class);
return query.getResultList();
}
entityManager will be null so it will cause the null pointer exception.
The solution? Declare QuestionRepository as an EJB too, as example . This way the Persistence Context injection will be automatically done by the server and the entity manager will be initialized at the moment you try to execute the query

I was kind of roped into using maven, Hibernate, spring and JPA repositories in a small project. I cheerfully assumed that information found here
http://docs.spring.io/spring-data/jpa/docs/1.4.2.RELEASE/reference/html/jpa.repositories.html
will be enough to create at least a simple application. Unluckily that's not the case. I've managed to read data from a MySQL database, but as for now have been unable to insert any data.
Here is a simple 'User' model class.
#Entity
#Table(name = "ctuser")
public class User implements Serializable {
private static final long serialVersionUID = 1L;
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
private long uid;
#Column(name = "Gmail", nullable = false)
private String gmail;
public String getGmail() {
return gmail;
}
public void setGmail(String gmail) {
this.gmail = gmail;
}
#Override
public String toString() {
return getGmail();
}
}
I've created an appropriate repository interface...
package put.io.come_together.service.persistance.repository;
import org.springframework.data.jpa.repository.JpaRepository;
import put.io.come_together.model.User;
public interface UserRepository extends JpaRepository<User, Long> {
User findUserByUid(long uid);
User save (User obj);
}
...an interface for the service...
public interface UserService {
User getUser(long uid);
User addUser(User obj);
List<User> getAll();
}
...and implementation of the interface.
#Service
public class UserServiceImpl implements UserService {
private final UserRepository userRepository;
#Autowired
public UserServiceImpl(UserRepository userRepository) {
this.userRepository = userRepository;
}
#Override
public User getUser(long uid) {return userRepository.findUserByUid(uid);
}
#Transactional
#Override
public User addUser(User obj) {return this.userRepository.saveAndFlush(obj);}
#Override
public List<User> getAll() {
return userRepository.findAll();
}
Finally I'm trying to present as the data as well as insert something into database.
#Controller
public class HomePageController {
#Autowired
private UserService userService;
private static final String USER_MAP_KEY = "groups";
private static final String USER_LIST_TEMPLATE_NAME = "groupList";
#RequestMapping("/")
String hello(Map<String, Object> model) {
User osoba = new User();
osoba.setGmail("ADAMWEST");
userService.addUser(osoba);
List<User> userGroupsList = userService.getAll();
model.put(USER_MAP_KEY, userGroupsList);
return USER_LIST_TEMPLATE_NAME;
}
}
If I leave out the userService.addUser(osoba); line, everything works fine. I can see the data read from the database neatly laid out. But when I try to actually use the .addUser() method my localhost puts out a white label error page.
White label Error Page
This application has no explicit mapping for /error, so you are seeing this as a fallback.

There was an unexpected error (type=Internal Server Error, status=500).
could not execute statement; nested exception is org.hibernate.exception.GenericJDBCException: could not execute statement
Would you kindly tell me what is it that I'm doing wrong? I've been trying to solve the problem for some time now, and thoroughly lost hope.
Here is the stack trace of the exception. The error concerns field 'UID' not having a default value, but I marked it as an #Id field. I also dropped the entire database and set it up again, seeing as it helped someone with a similar problem.

You said Hibernate that the ID was autogenerated using the strategy AUTO. This strategy, with MySQL, consists in letting the database generate the ID using an auto-increment column. So if you haven't defined uid as auto-increment, that won't work.
In my Java EE 6 / JPA 2 project I have a Map property advantages in the Employee entity:
#ElementCollection
private Map<String, Float> advantages;
The key represents the advantage name and the value represents the cost associated with the advantage name. This is mapped to a table with three columns Employee_Id, Advantages and Advantages_Key. I'd like to persist a Map entry where the Employee_Id is the Id of the selected Employee in the datatable. How can I achieve this?
UpDate: I tried this method in the Employee Business class where I injected the interface EmployeeManagerLocal:
public Map<String, Float> addAdvantage(String advantageName, Float cost, String
employeeId) {
Employee emp = employeeManagerLocal.findById(employeeId);
Map<String, Float> advantages = new HashMap<>();
advantages.put(advantageName, cost);
emp.setAdvantages(advantages);
return advantages;
}
Then, I call this method in the Emlpoyee Managed Bean:
public String addAdvantage(){
employeeBusinessLocal.addAdvantage(advantageName, cost, selectedEmployee.getId());
return "index";
}
But this exception is shown:

I'm using Glassfish 3.1.2.2
Use
#CollectionTable(name="table_name", joinColumns=#JoinColumn(name="Employee_id"))
#MapKeyColumn(name="Advantages_Key")//the name of the advantage (String)
#Column(name="Advantages")//the cost (Float)
#ElementCollection
private Map<String, Float> advantages;
I have an AbstractDAO class:
public abstract class AbstractDAO<T> {
private Class<T> entityClass;
protected abstract EntityManager getEntityManager();
...
public T update(T entity) {
return getEntityManager().merge(entity);
}
...
}
this class has the methods to persist, update, find, findAll, etc. I have DAO's that extends from this one, this SolicitudDAO is one of them:
#Stateless
#LocalBean
public class SolicitudDAO extends AbstractDAO<Solicitud>{
#PersistenceContext
EntityManager em;
public SolicitudDAO() {
super(Solicitud.class);
}
#Override
protected EntityManager getEntityManager() {
return this.em;
}
}
And and entity like:
#Entity
#Table(name = "SOLICITUD")
public class Solicitud implements Serializable {
private Long folioSisap;
private static final long serialVersionUID = 1L;
#SequenceGenerator(name = "SOLICITUD_ID_SEQ", sequenceName = "SOLICITUD_ID_SEQ", allocationSize = 1, initialValue = 1)
#Id #GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "SOLICITUD_ID_SEQ")
#Column(name = "SOLICITUD_ID")
private Long solicitudId;
}
From my view, I load my list through a findAll, then I can choose one element, and this is passed to a new Solicitud selectedSolicitud in my back bean. The problem is when I try to merge some changes this:
#EJB
SolicitudDAO solicitudDAO;
...
public Solicitud actualizaSolicitud(Solicitud solicitud) {
solicitud.setFolioSisap(solicitud.getFolioSisap()+1);
return solicitudDAO.update(solicitud);
}
...
If I run this, in my log shows this stacktrace:
...

I'm Using JPA 2 implements Hibernate. BD Oracle 11g.
"FROM keyword not found where expected"? C'mon, I'm not using JPQL, is just the "merge" JPA implementation.
Thanks for your time.
I'm having a problem here, when i've started work with JSF and JPA. I can't make a jsf "request" using a commandButton to a method in my EJB. Let me show the code:

I won't paste the persistence code, to keep the post clean, the problem is not in this tier.
Thanks in advance!
EDIT:
Sorry! I didn't paste the ManagedBean, here it is:
package model;
import javax.ejb.EJB;
import javax.faces.bean.ManagedBean;
import javax.faces.bean.RequestScoped;
import negocio.MapaDeMesas;
import persistence.Mesa;
#ManagedBean
#RequestScoped
public class IndexBean {
#EJB
private MapaDeMesas mp;
private Mesa mesa;
public IndexBean() {
mesa = new Mesa();
}
public void insereMesa(){
mp.insereMesa(mesa);
}
public void setMesa(Mesa mesa) {
this.mesa = mesa;
}
public Mesa getMesa() {
return mesa;
}
}
But now i got another problem the new stacktrace is this one, i can't find the problem with my "getTransaction()" ideas?

Sorry the loooong post!
The first error can be solved by changing the method signature in the facelet.
Change
<h:commandButton id="insertTable" value="OK"
action="#{indexBean.insereMesa(mesa)}">
to
<h:commandButton id="insertTable" value="OK"
action="#{indexBean.insereMesa()}">
The reason of the second error is that methods of an EJB are automatically wrapped in a transaction, so you don't need to call getTransaction(), begin() and commit().
Change
public void insereMesa(Mesa m){
EntityTransaction et = em.getTransaction();
et.begin();
em.persist(m);
et.commit();
}
to
public void insereMesa(Mesa m){
em.persist(m);
}
The same applies to your other EJB method.
Edit: ok you've just updated your post with the bean. Regarding your Transaction error - you can't do bean managed transactions if you're using container managed transactions. You'll have to update your persistence.xml file to not use JTA, or just remove your transaction management code and let the container handle it for you.
You'll need to wrap your EJB inside a JSF (or CDI) managed bean - it seems like you're halfway there by using #{indexBean} but I assume you haven't defined it?
If you update your facelets page (remove the method argument).
<h:commandButton id="insertTable" value="OK" action="#{indexBean.insereMesa()}">
And define a request-scoped managed bean (this one's a JSF one, not CDI) which injects your EJB and defines a method which can be called from your facelets page...
package negocio;
import javax.ejb.EJB;
import javax.faces.bean.ManagedBean;
import javax.faces.bean.RequestScoped;
import persistence.Mesa;
#ManagedBean
#RequestScoped
public class IndexBean {
#EJB
private MapaDeMesas mapaDeMesas;
private Mesa mesa;
public Mesa getMesa() {
return mesa;
}
public void setMesa(Mesa mesa) {
this.mesa = mesa;
}
/**
* Called by the command button.
* #return outcome
*/
public String insereMesa(){
mapaDeMesas.insereMesa(mesa);
return null; // navigates to same page (change if required)
}
}
Hope this helps.
I am facing problem with JPA. I have a problem where I need to insert new user and setup its relationship with user at the same time.
==> Database Design is as following:
SystemUsers:
UserName(pk)
Password
SystemClassifiedGroups:
SystemClassifiedGroupName
UserName
==> I have written following logic in EJB
#Override
public void addUser(SYSTEM_CLASSIFIED_USER_GROUPS systemClassifiedUserGroup,
String userName,
String password,
String emailID,
String secretQuestion,
String secretAnswer,
String firstName,
String lastName,
String profilePictureURL,
Date birthDate,
String address1,
String address2,
String cityName,
String zipCode,
short stateID,
short countryID,
String officePhoneNumber) {
FeedBack objFeedBack = null;
String methodName = CLASS_NAME + ".addUser";
try {
SystemUsers objSystemUser=new SystemUsers(userName, password, emailID, firstName, lastName, address1, cityName);
SystemClassifiedUserGroups tempGrp=new SystemClassifiedUserGroups(systemClassifiedUserGroup.name());
States objState = new States(stateID);
Countries objCountry = new Countries(countryID);
objSystemUser.setSecretQuestion(secretQuestion);
objSystemUser.setSecretAnswer(secretAnswer);
objSystemUser.setProfilePictureURL(profilePictureURL);
objSystemUser.setBirthDate(birthDate);
objSystemUser.setAddress2(address2);
objSystemUser.setStateID(objState);
objSystemUser.setCountryID(objCountry);
objSystemUser.setOfficePhoneNumber(officePhoneNumber);
objSystemUser.setZipCode(zipCode);
ArrayList<SystemUsers> lstUser = new ArrayList<SystemUsers>();
lstUser.add(objSystemUser);
tempGrp.setUserName(objSystemUser);
tempGrp.setSystemClassifiedGroupName(systemClassifiedUserGroup.name());
em.persist(tempGrp);
em.persist(objSystemUser);
} catch (Exception ex) {
ex.printStackTrace();
}
}
==> And call the method by following :
asr.addUser(SYSTEM_CLASSIFIED_USER_GROUPS.ADMIN,
"raj",
"pass",
"abc#yahoo.com",
"Color",
"purple",
"Raj",
"Champaneriya",
"abj.jpg",
new Date(),
"jolly1",
"jolly2",
"surat",
"395007",
(short) 1,
(short) 1,
"3201708");
==> But I got following Exception in glassfish console
SEVERE: java.lang.IllegalArgumentException: Object: BusinessFacade.Entities.SystemUsers[ userName=raj ] is not a known entity type.

Thanks in advance
Show me the exact line in the code where the error occurs. I assume it is at the point you call em.persist(tmpGrp). You must save the user first, otherwise the EntityManager will not be able to find any instance of the user, or you need to specify the way the user is managed in the group by adding the following in the group class:
#OneToOne(cascade = {CascadeType.PERSIST, CascadeType.MERGE})
SystemUsers userName;
