I get this exception for the createEntityManagerFactory row:

I'm running into a weird issue that hasn't been reported by others from what I could tell, there may be a bug when using createNativeQuery. I have tried so many things to understand why to no avail.
Current Environment:
EclipseLink 2.7.3 JPA provider
PostgreSQL 10.6.1 Database
Eclipse Photon IDE
JRE 1.8.0_121
When executing:
Long total = (Long) em.createNativeQuery("Project.count").getSingleResult();
It's throwing the following:
javax.persistence.PersistenceException: Exception [EclipseLink-4002] (Eclipse Persistence Services - 2.7.3.v20180807-4be1041): org.eclipse.persistence.exceptions.DatabaseException

<query>Select count(*) as total from public.project</query>
</named-native-query>

From what I could tell, the named native query is not getting resolved back to the actual SQL contents.
Executing this works (and it resolves the named-native-query name "Project.count"):
Long total = (Long) em.createNamedQuery("Project.count").getSingleResult();
This also works:
Long total = (Long) em.createNativeQuery("Select count(*) from project").getSingleResult();
I didn't want to resort to JPQL for other reasons unimportant to this thread and I also need to implement SQL Resultset Mappings.
Any insight on this would be greatly appreciated. I truly ran out of ideas.
createNamedQuery: Used to define queries wthe ith name in mapping file or annotation
createNativeQuery: Used to execute native/pure SQL queries
Since you use createNativeQuery method with a named query you are getting above error
I'm using EclipseLink and Java Persistence API to connect to local database, however when I'm creating EntityManager object, I'm getting following error:

Error stack trace point at line where I create EntityManager:

}
I've added eclipselink and java persistence API through Maven Dependencies and JDBC driver to project classpath. This is my persistence.xml file (located in META-INF directory in folder with project packages):
<?xml version="1.0" encoding="UTF-8" ?>
<persistence xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

</properties>
</persistence-unit>
</persistence>
What is the cause of problem and how it can be solved? I know that JDBC driver itself probably is working correctly because when I intentionally put wrong password into persistence.xml file I'm getting error about failed authorization. Database is set up and working because I can create queries and insert data into database from shell and from eclipse toad extension.
Thank you in advance for help.
Edit: Problem lies in user name and/or password in persistence.xml. When I changed it to user and password of different length, connection works without problems. However still I have no idea why that was happening.
I can confirm the odd behaviour with EclipseLink version 2.6.4, as I reproduced your setup . Here's the full stack trace:

It seems, this relates to a bug in org.eclipse.persistence.internal.security.JCEEncryptor. While debugging, I found that there are certain password lengths which cause the observed behaviour, e.g. for 123456.
Solution
Now the good part of my answer: This bug was fixed with version 2.6.5-RC1. Moreover, it also works as expected with the latest 2.6.5-RC2 release candidate (available since June 2017). In case you have a Maven project, change the version string of the EclipseLink dependency like so:
<dependency>
<groupId>org.eclipse.persistence</groupId>
<artifactId>eclipselink</artifactId>
<version>2.6.5-RC2</version>
</dependency>
If this is a standalone project, find the latest 2.6.5-RC2 jar file on Maven Central. Just remove the old jar file and put the new one in the application's class path.
Btw, when I changed the PW to 123456789 in the database as well as in persistence.xml it worked even with the bugged version 2.6.4. Odd, isn't it?
Hope it helps.
I have the next problem:
I am doing a project using JPA and Restfull whit netbeasn and postgres, I have the following persistence
<?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.1" xmlns="http://xmlns.jcp.org/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/persistence http://xmlns.jcp.org/xml/ns/persistence/persistence_2_1.xsd">

<jta-data-source>data_cotratacion</jta-data-source>
<exclude-unlisted-classes>false</exclude-unlisted-classes>
<properties/>
</persistence-unit>
And also the following code using the EntityManager:
#GET
public String crearPersona(
#QueryParam("id") String id,
#QueryParam("name") String name,
#QueryParam("gender") String gender,
#QueryParam("date") String date){
Persona p = new Persona();
p.setId(id);
p.setName(name);
p.setGender(gender);
p.setDate(stringToDate(date));
try {
EntityManagerFactory emf = Persistence.createEntityManagerFactory("PruebaPersitenciaPU");
EntityManager em = emf.createEntityManager();
em.getTransaction().begin();
em.persist(p);
em.getTransaction().commit();
return "Usuario Creado "+id;
} catch (Exception e) {
return "Usuario no creado error: "+e;
}
}
but try this sends me this error:
Usuario no creado error: javax.persistence.PersistenceException: Exception [EclipseLink-7060] (Eclipse Persistence Services - 2.5.2.v20140319-9ad6abd): org.eclipse.persistence.exceptions.ValidationException Exception Description: Cannot acquire data source [data_cotratacion].

Sounds like there is no JDBC datasource configured with the name data_cotratacion. You need to configure this JDBC resource on your application server.
Or you need to create your persistence unit by using the wizard in netbeans go in the menu to File > New File Then select Persistence in the left box and Persistence Unit in the right box.
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.

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?

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