happening " java.lang.ExceptionInInitializerError " Caused by " Unable to build EntityManagerFactory " in JPA project

I want create a web application and use JPA for model layer in MVC for the first time . But I'm having trouble.
The program shows me this error :

my IDE = IntellyJ Idea
I use Oracle 11g .
I tried to solve the problem by solving similar questions, but I could not .
for example I checked the following topics that were more similar to my problem :
[Error creating bean with name 'entityManagerFactory' defined in class path resource : Invocation of init method failed
[Getting Exception in thread "main" java.lang.ExceptionInInitializerError Exception
Additional explanation: No tables have been created in the database so far.

Looks like problem is with #JoinColumn(name = "FK_PERSON",referencedColumnName = "UID")
referencedColumnName attribute points to the related column in asociated/referenced entity, i.e. column name of the primary key. By default it is primary key of associated entity. You are not required to fill the referencedColumnName if the referenced entity has single column as PK, because there is no doubt what column it references (i.e. primary key column of associated entity).
change that line to #JoinColumn(name = "FK_PERSON") it should work.
For more info about referencedColumnName refer to "What is referencedColumnName used for in JPA?"

DAO methods all return NullPointerException

I'm developing a little web app for an exam purpose, but I'm encountering several problems with the Dao methods, they all return a NullPointerException.
This is the Façade:
#Stateless(name = "administratorFacade")
public class AdministratorFacade {
#PersistenceContext(unitName = "clinic-unit")
private EntityManager em;
public Administrator getAdministrator(String username){
AdministratorDaoJPA administratorDao = new AdministratorDaoJPA();
Administrator administrator = administratorDao.findByUsername(username);
return administrator;
} //An example of method that uses DAO
This is the DAO:
public class AdministratorDaoJPA implements AdministratorDao {
#PersistenceContext(unitName = "clinic-unit", type = PersistenceContextType.EXTENDED)
private EntityManager em;
#Override
public Administrator findByUsername(String username){
Query query = em.createQuery("SELECT a FROM Administrator a WHERE a.username=?");
return (Administrator)query.setParameter(1,username).getSingleResult();
}
And there is Administrator.java:
#Entity
#NamedQuery(name="allAdministrators", query="SELECT a FROM Administrator a")
public class Administrator {
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
private Long id;
#Column(unique = true, nullable = false)
private String username;
#Column(nullable = false)
private String name;
#Column(nullable = false)
private String surname;
#Column(nullable = false)
private String pwd;
public Administrator(){}
public Administrator(String username, String name, String surname, String pwd) {
this.username=username;
this.name = name;
this.surname=surname;
this.pwd = pwd;
}
public String getUsername() {
return this.username;
}
public void setUsername(String username) {
this.username = username ;
}
public String getName() {
return this.name;
}
public void setName(String name) {
this.name = name;
}
public String getPwd() {
return this.pwd;
}
public void setPwd(String pwd) {
this.pwd = pwd;
}
public String getSurname() {
return surname;
}
public void setSurname(String surName) {
this.surname = surName;
}
#Override
public boolean equals(Object o) {
Administrator adm = (Administrator) o;
return adm.getUsername().equals(this.getUsername());
}
#Override
public int hashCode() {
return this.getUsername().hashCode();
}
#Override
public String toString() {
final StringBuilder sb = new StringBuilder();
sb.append("Adinistrator");
sb.append("{id='").append(id);
sb.append(", name='").append(name);
sb.append(", surname='").append(surname);
sb.append(", username='").append(username);
sb.append("}\n");
return sb.toString();
}
}

I'm using JPA with Tomee and JSF 2.2.
I hope you will help me to go through this :)

You're using
new AdministratorDaoJPA()
to get your DAO. So the container can't inject anything into that object, and the entityManager field thus has its default value: null.
For injection to happen, you must let the container create and inject the objects.
You also don't need the entity manager in your facade, so there is no point in injecting it there. What you need to inject is the DAO:
#Inject
private AdministratorDaoJPA administratorDao;

UnmarshalException while consuming a web service

I have a web service based on a number of entity classes. one of them is shows below
#Entity
#Table(name = "users")
#XmlRootElement
#NamedQueries({
#NamedQuery(name = "Users.findAll", query = "SELECT u FROM Users u"),
#NamedQuery(name = "Users.findByUserName", query = "SELECT u FROM Users u WHERE u.userName = :userName"),
#NamedQuery(name = "Users.findByUserPassword", query = "SELECT u FROM Users u WHERE u.userPassword = :userPassword")})
public class Users implements Serializable {
private static final long serialVersionUID = 1L;
#Id
#Basic(optional = false)
#Column(name = "user_name")
private String userName;
#Basic(optional = false)
#Column(name = "user_password")
private String userPassword;
#JoinColumn(name = "user_category_id", referencedColumnName = "category_id")
#ManyToOne(optional = false)
private UserCategory userCategoryId;
#OneToMany(cascade = CascadeType.ALL, mappedBy = "userName")
private List<UserRecord> userRecordList;
public Users() {
}
public Users(String userName) {
this.userName = userName;
}
public Users(String userName, String userPassword) {
this.userName = userName;
this.userPassword = userPassword;
}
public String getUserName() {
return userName;
}
public void setUserName(String userName) {
this.userName = userName;
}
public String getUserPassword() {
return userPassword;
}
public void setUserPassword(String userPassword) {
this.userPassword = userPassword;
}
public UserCategory getUserCategoryId() {
return userCategoryId;
}
public void setUserCategoryId(UserCategory userCategoryId) {
this.userCategoryId = userCategoryId;
}
#XmlTransient
public List<UserRecord> getUserRecordList() {
return userRecordList;
}
public void setUserRecordList(List<UserRecord> userRecordList) {
this.userRecordList = userRecordList;
}
#Override
public int hashCode() {
int hash = 0;
hash += (userName != null ? userName.hashCode() : 0);
return hash;
}
#Override
public boolean equals(Object object) {
// TODO: Warning - this method won't work in the case the id fields are not set
if (!(object instanceof Users)) {
return false;
}
Users other = (Users) object;
if ((this.userName == null && other.userName != null) || (this.userName != null && !this.userName.equals(other.userName))) {
return false;
}
return true;
}
#Override
public String toString() {
return userName;
}
}
I was able to successfully deploy the web service and then i added a new Restful web client using netbeans, which created the following class
public class Client {
private WebTarget webTarget;
private javax.ws.rs.client.Client client;
private static final String BASE_URI = "http://localhost:31691/ProductionEntitiesService/api";
public Client() {
client = javax.ws.rs.client.ClientBuilder.newClient();
webTarget = client.target(BASE_URI).path("entities.users");
}
...
public <T> T find_XML(Class<T> responseType, String id) throws ClientErrorException {
WebTarget resource = webTarget;
resource = resource.path(java.text.MessageFormat.format("{0}", new Object[]{id}));
return resource.request(javax.ws.rs.core.MediaType.APPLICATION_XML).get(responseType);
}
public <T> T findAll_XML(Class<T> responseType) throws ClientErrorException {
WebTarget resource = webTarget;
return resource.request(javax.ws.rs.core.MediaType.APPLICATION_XML).get(responseType);
}
public void close() {
client.close();
}
}
This line of code then returned an xml result of the query
result = c.findAll_XML(String.class);
which had this format
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<userss>
<users>
<userCategoryId>
<categoryId>2</categoryId>
<userCategory>admin</userCategory>
</userCategoryId>
<userName>admin</userName>
<userPassword>d033e22ae348aeb5660fc2140aec35850c4da997</userPassword>
</users>
</userss>
However, this line of code
List<Users> l = (List<Users>)c.findAll_XML(Users.class);
produces an exception, which seems to be caused by the "userss" tag that surrounds the xml result, I'm not sure how that came about.
Can anyone help me resolve this?

JPA can't access PostgreSQL due to cast problems

I'm writing a Java ee7 Webapp with PostgreSQL 9.1.1, Glassfish 4, EclipseLink 2.
My problem is, that I can't access some tables of the database.
I have two (actually 3) entity-classes, which I autogenerated with netbeans from my DB.
#Entity
#Table(name = "webappuser")
#XmlRootElement
#NamedQueries({
#NamedQuery(name = "Webappuser.findAll", query = "SELECT w FROM Webappuser w"),

Your name query("Cardbox.findByUser") should be like below. Currently you are using another object in where condition instead of a field.
SELECT c FROM cardbox c WHERE c.user.username = :user
Here c.user represents the Entity Webappuser which has the field username.

WARNING: Local Exception Stack:
Exception [EclipseLink-4002] (Eclipse Persistence Services - 2.3.2.v20111125-r10461): org.eclipse.persistence.exceptions.DatabaseException

Try replacing
#Column(name = "condition")
with
#Column(name = "`condition`")
or, if that doesn't work,
#Column(name = "\"condition\"")
MySQL is complaining because CONDITION is a reserved word and you must quote it if you wish to use it for a column name. Enclosing the column name in backticks or double quotes tells JPA to escape the column name when it passes the query to the database.
This answer goes into more detail about whether to use backticks or double quotes.

I can reconfirm that if one uses a column name which happens to be a reserved word in MySQL, then one gets the exception above ("javax.ejb.EJBException...JPA eclipse link Exception: com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException"). I spent half a day trying to figure it out because I was using 'PRIMARY' (column of type Boolean; just mentioning it but it is irrelevant to/does not affect this exception ) as a column title; which is also a Reserved Word in MySQL. The error message is rather long and only after careful consideration of what "syntax error" may mean I 'got it'.
