I am beginning with hibernate and JPA and I have been following several tutorials on JPA with eclipse link on Netbeans.

However, while still working on Netbeans I downloaded the hibernate-release-5.2.7.Final.zip manually from Hibernate web page and as stated here: http://docs.jboss.org/hibernate/orm/5.2 ... _artifacts.

I added the lib/required directory and the lib/jpa-metamodel-generator/ to my java application and mysql-connector jar. After that, I created my persistence.xml as in gist.

Then I created a sample Entity Prueba and I added a JPA ControllerClass from Entity through NetBeans wizard next, to that I created a quick Dao for testing Hibernate.

After creating my main class everything works fine the object is added to MySQL but the app doesn't close on finish I show the log and everything on gist https://gist.github.com/Paulwerito/111b ... c0452b8b2e

That's because you didn't close the EntityManagerFactory.

Add the following line

Code:

pbdao.destroy();

at the end of your test code:

Code:

public static void main(String[] args) {
        Prueba pb = new Prueba();
        PruebaDao pbdao = new PruebaDao();
        
        pb.setNombre("elexit");
        
        pbdao.addPrueba(pb);

        pbdao.destroy();               
}

where the destroy method in PruebaDao looks like this:

Code:

public void destroy() {
        this.em.close();
}

I was encountering a similar error but got it solved with your reference. Thanks a lot for the solution @vlad :)
