The persistence doesn't recognize the entity class

The persistence doesn't recognize the entity class - java

I am developing a java program about some lotteries of my country, it has a database with the lottos and other numbers. There is no problem with the entity classes, but when I run the problem my persistence unit does not recognize one entity class. I am a beginner in java, thanks in advance.
Here is the Numbers entity class:
#Entity
#Table(name = "NUMBERS")
#XmlRootElement
#NamedQueries({
#NamedQuery(name = "Numbers.findAll", query = "SELECT n FROM Numbers n")
, #NamedQuery(name = "Numbers.findById", query = "SELECT n FROM Numbers n WHERE n.id = :id")
, #NamedQuery(name = "Numbers.findByNum", query = "SELECT n FROM Numbers n WHERE n.num = :num AND n.lotto = :lotto")
, #NamedQuery(name = "Numbers.findByAssociated", query = "SELECT n FROM Numbers n WHERE n.num = :num AND n.associated = :associated AND n.lotto = :lotto")
, #NamedQuery(name = "Numbers.findByLotto", query = "SELECT n FROM Numbers n WHERE n.lotto = :lotto")})
public class Numbers implements Serializable {
private static final long serialVersionUID = 1L;
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
#Basic(optional = false)
#Column(name = "ID")
private Integer id;
#Basic(optional = false)
#Column(name = "NUM")
private int num;
#Basic(optional = false)
#Column(name = "ASSOCIATED")
private int associated;
#Basic(optional = false)
#Column(name = "LOTTO")
private String lotto;
And the code that I use to insert Numbers in the database:
public static boolean insertAlert(EntityManager em, Numbers an) {
boolean success = false;
Alert alert = Check.createAlert(Check.CONFIRMATION, "Añadir números asociados", "¿Deseas añadir estos números?");
Optional<ButtonType> result = alert.showAndWait();
if (result.get() == ButtonType.OK) {
em.getTransaction().begin();
em.persist(an);
if (em.isJoinedToTransaction()) {
em.getTransaction().commit();
System.out.println("NUMBERS SUCCESSFULLY ADDED!");
alert = Check.createAlert(Check.INFORMATION, "OK", "Números añadidos!");
alert.showAndWait();
success = true;
}
em.clear();
}
return success;
}
The persistence.xml:

The persistence unit recognizes all my entity classes but not this one, I don't know how to resolve this...

I had the same problem and none of the answers here fixed it.
My solution was to updated my EclipseLink version from 2.5.1 to the latest version 2.7.7 as described in this other post.

Persist only takes on entity not a list of.
So you have to iterate over the array and persist each Numbers object separately.
for (Numbers n : ans) {
em.persist(ans);
}

Common reasons for this error:
An older persistence.xml file is on the class path that doesn't
have your lotter.Numbers entry.
The class loader used to obtain the EntityManager isn't the same one
that loaded the 'an' Answer instance you are passing to the
em.persist call.
The first issue is far more common, and can be found more easily by enabling EclipseLink logging and then checking the log when it deploys the persistence unit to see what classes and mappings are loaded. Variations of it are just deploying the wrong jar, having an older jar on the class path first etc.
EclipseLink uses the class to lookup the metadata in a hash map, so if different class loaders are used, it won't find anything for it. This is a less common issue that depends on how you are loading your EntityManagerFactory and the container classloader structure. You would have problems with more then just one of your JPA entities, but it would depend on where they are coming from too.

Cannot create index with automated generated entity from DB org.hibernate.AnnotationException: Unable to create index

I'm trying to deploy an EAR application (includes ejb and war modules). The problem is it cannot create indexes of a foreign key in associative entity (WorkerHasRole). Every entity with relationships was created automatically in IntelliJ. I am running it on Wildfly 25.0.0. I can't figure it out even with help of the internet...

Hibernate not persisting entity to MySql - Wildfly 10

I'm using MySQL db to persist my entities in this project. I don't get any error messages from hibernate, but when I check in the database it's empty and no tables are created.
persistence.xml (edit: datasource added and transaction-type changed to JTA)

public class Book implements Serializable {

I persist entity in EJB like this:
#Named

public class BookEJB {
#PersistenceContext(unitName = "punit")
EntityManager em;
public Book createNewBook(Book book) {
em.persist(book);
System.out.println("Book \"" + book.getTitle() + "\" persisted!");
return book;
}
}
Update
I fixed persistence.xml, defined datasource in standalone.xml and put jdbc driver jar in server's directory following this tutorial.
But I get this exception:
23:12:11,374 INFO [org.jboss.as.jpa] (MSC service thread 1-3) WFLYJPA0002: Read persistence.xml for punit
23:12:11,625 ERROR [org.jboss.as.controller.management-operation] (Controller Boot Thread) WFLYCTL0013: Operation ("add") failed - address: ([

"org.wildfly.data-source.MySqlDS is missing [jboss.jdbc-driver.mysql]",
"jboss.driver-demander.java:jboss/datasources/MySqlDS is missing [jboss.jdbc-driver.mysql]"
]}
PROBLEM SOLVED
In persistence.xml replaced <jta-data-source>jdbc/MySqlDS</jta-data-source> with <jta-data-source>java:jboss/datasources/MySqlDS</jta-data-source> which was the correct value of jndi-name attribute of my datasource definition inside standalone.xml file.
Also I've incorrectly put module.xml and jdbc connector jar inside modules\system\layers\base\com\mysql\driver\main but instead it needs to go to
modules\system\layers\base\com\mysql\main.
Seems i've been following some other tutorial alongside with the one in my post. ^^

Lets see extracts from the JPA 2.1 specification:
8.2.1.2 transaction-type
The transaction-type attribute is used to specify whether the entity managers provided by the entity manager factory for the persistence unit must be JTA entity managers or resource-local entity managers. The value of this element is JTA or RESOURCE_LOCAL. A transaction-type of JTA assumes that a JTA data source will be provided—either as specified by the jta-data-source element or provided by the container. In general, in Java EE environments, a transaction-type of RESOURCE_LOCAL assumes that a non-JTA datasource will be provided. In a Java EE environment, if this element is not specified, the default is JTA. In a Java SE environment, if this element is not specified, the default is RESOURCE_LOCAL.
You haven't specified the transaction-type attribute in the persistence-unit element. So, according to the spec (see the highlighted part above) you have the default which is JTA.
8.2.1.5 jta-data-source, non-jta-data-source
In Java EE environments, the jta-data-source and non-jta-data-source elements are used to specify the JNDI name of the JTA and/or non-JTA data source to be used by the persistence provider. If neither is specified, the deployer must specify a JTA data source at deployment or the default JTA data source must be provided by the container, and a JTA EntityManagerFactory will be created to
correspond to it.
You haven't also specified jta-data-source element in your persistence.xml as well, and I assume you haven't specified a JTA datasource during deployment. That means the default datasource will be provided by the container (see the highlighted text in the spec).
And this datasource is not pointing to your MySQL database. The default in Wildfly, unless you reconfigured it, is H2 database. So your program might be creating and populating tables in the default database. So you need to configure a datasource in Wildfly first and specify it in the persistence.xml.
That might be the reason for:
I also ran query on entity manager after persist and it returns me a list of all persisted books, but none of them are in the database.

It seems like you insert in one db, but check another db. Could you show datasource config?
P.S. It should be comment, but not enough rating(

jpa mysql table does not exists

I am trying to insert a Employee entity into the database. I am using JPA and the database is mysql.
When I try to insert the entity, it gives me test.employee does not exist. I assume that I dont have to create
the table. Entity will automatically create the table with the annotated name.
Please find the exception and code below.

You will need extra configuration if you want an auto generated varchar.
The generation of DDL is translating to:
CREATE TABLE employee (EMP_ID VARCHAR(255) AUTO_INCREMENT NOT NULL, FIRST_NAME VARCHAR(255), LAST_NAME VARCHAR(255), PRIMARY KEY (EMP_ID))
and the log is saying:
Internal Exception: com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: Incorrect column specifier for column 'EMP_ID'
Error Code: 1063
MySql is rejecting EMP_ID becuase it cant have AUTO_INCREMENT with varchar, and you need to specify the auto generation for it. Probably Derby has this feature, and it works different for MySql.
You might wanna look in this answer.
Or just change the type of EMP_ID to an integer number if you dont mind the type or for a quick test.

Could be you mysql data is corrupted.
Go to Mysql home directory and delete all .frm extension. and restart Msysql server.
Solved.

Intellij 13 EclipseLink Class [] not found Error

i ve a huge problem with intellij 13.0.1. I set up a JPA Project for the first time in intellij 13 and need some help to get some rid of an strange error.
Caused by: Exception [EclipseLink-4003] (Eclipse Persistence Services - 2.5.1.v20130918-f2b9fc5): org.eclipse.persistence.exceptions.DatabaseException
Exception Description: Configuration error. Class [] not found.
I added a persistence Unit and add the datasource, if i test the connection it is successfull. I also added eclipselink in version 2.5.1 and postgres.jdbc.driver in 9.3-1100. I also installed Postgres # latest build. I get the error if i want to create an Entitymanager. Any idea what i could do to get rid of this error?
