The persistence doesn't recognize the entity class

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.

jpa mysql table does not exists autoGenerate doesn't work

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 tables must be created 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.

I haven't work with eclipselink, but checking a few example and can see that all have mentioned below 4 properties each time:
<property name="eclipselink.ddl-generation" value="drop-and-create-tables"/>
<property name="eclipselink.create-ddl-jdbc-file-name" value="createDDL_ddlGeneration.jdbc"/>
<property name="eclipselink.drop-ddl-jdbc-file-name" value="dropDDL_ddlGeneration.jdbc"/>
<property name="eclipselink.ddl-generation.output-mode" value="both"/>
might be the cause ?

the problem was at the database level and not with jpa I solved it by connecting to another database thx

I'd say that's your problem. You're explicitly specifying no driver. Omit it or use org.postgresql.Driver.

What should I do to fix the error?

I have same error with IntelliJ IDEA and Hybernate,
Caused by: org.postgresql.util.PSQLException: ERROR: cross-database references are not implemented: "mydb.public.media_types"
Same as yours,
Caused by: org.postgresql.util.PSQLException: ERROR: cross-database references are not implemented: "doodlenotes.public.projects"
I have found solution, for my trouble, and I suppose for your's too, my solution is just to remove attribute named, catalog from my hbm.xml file.
before:
`<class name="pkg.MediaTypesEntity" table="media_types" schema="public"` catalog="MyDB">
after:
<!-- catalog="MyDB" --removed -->
<class name="pkg.MediaTypesEntity" table="media_types" schema="public">
<!-- catalog="MyDB" --removed -->
<id name="id">
<column name="id" sql-type="serial" not-null="true"/>
</id>
<property name="txt">
<column name="txt" sql-type="text" length="2147483647"/>
</property>
</class>
I suppose reason is that database name was configured globally at hibernate.cfg.xml .
<hibernate-configuration>
<session-factory>
<property name="connection.url">jdbc:postgresql://localhost:5432/MyDB</property>
<property name="connection.driver_class">org.postgresql.Driver</property>
<mapping resource="pkg/MediaTypesEntity.hbm.xml"/>
<mapping class="pkg.MediaTypesEntity"/>
</session-factory>
</hibernate-configuration>
And, real reason, MyDB name can not be easily removed from JDBC connection string. Only several different hibernate-DBName.cfg.xml allowed.
