SOLVED
This question is about java hibernate.
When i run the Main class i get this error
Initial SessionFactory creation failed: org.hibernate.MappingException:
invalid configuration
Exception in thread "main" java.lang.NullPointerException
at principal.ClienteDAO.guardaCliente(ClienteDAO.java:38)
at principal.Main.main(Main.java:31)
C:\Users\Nico\AppData\Local\NetBeans\Cache\8.2\executor-snippets\run.xml:53: Java returned: 1
BUILD FAILED (total time: 2 seconds)
Have no idea why im getting that exception
my hibernate.cfg.xml is
<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://hibernate.org/dtd/hibernate-mapping-3.0.dtd">

</hibernate-configuration>
EDIT 2:
So, i dont know why, but i change the hibernate.cfg.xml and now it works, here it is
<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration PUBLIC

solved? we'll see
I think you might need to close your hibernate-configuration tag in your xml.

Hibernate won't retrieve data even though the data exists in the table. Running the query directly from SQL Server Management Studio shows the expected results. Any idea what am I missing?
Java:
List<User> userCollection= session.createSQLQuery("select column1, column2 from myTable").addEntity(User.class).list();

I read that i should change the "Doctype" and i did from other answers i have found, yet this error occurs:
Unable to perform unmarshalling at line number 8 and column 63 in RESOURCE hibernate.cfg.xml. Message: cvc-elt.1: Cannot find the declaration of element 'hibernate-configuration'.
Your dtd url is false ... seems like hibernate-configuration-5.0.dtd doesn't exist ... use this :
http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd
change the whole header :
<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD//EN"
"http://www.hibernate.org/dtd/hibernate-configuration-5.0.dtd">

TO
<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration

<hibernate-configuration>
Try to add this header block. It works for me and also check parse error in your XML file.
<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration PUBLIC

I'm an Hibernate beginner user, I created a very simple application to test it !
But I get this error in the console :

}
AND finally 2 classes for my objects ( Produit and Categorie ) and their Configuration files !
What do you think may be the source of this error ?
Thank you :)
The dialect for MySql with MyISAM(if that is what you have) should be:
org.hibernate.dialect.MySQLMyISAMDialect
I am new to Hibernate .... i tried this code but i got Could not parse configuration: NewFile.cfg.xml (name of .cfg.xml file)

The end tag for <hibernate-configuration> is missing:

Your opening tag not match the ending tag.
I'm trying to set up Hibernate, and since 4.0.0 just came out I naturally decided to go with that. It seems that no matter what way I try to create a SessionFactory, it always leads to the same error:
Initial SessionFactory creation failed.java.util.ServiceConfigurationError: org.hibernate.integrator.spi.Integrator: Provider org.hibernate.envers.event.EnversIntegrator could not be instantiated: java.lang.ClassCastException: Cannot cast org.hibernate.envers.event.EnversIntegrator to org.hibernate.integrator.spi.Integrator
It seems like there is something wrong with my Hibernate configuration but I can't figure out what. Here's my hibernate.cfg.xml:
<?xml version='1.0' encoding='utf-8'?>

Does anyone spot anything out of the ordinary, or do you have other ideas?
I found no way to get Hibernate 4.0.0 CR4 working. Switching to 3.6.7 resolved the problem and works just fine. I conclude that there must be some bug in the release, and will file a bug report.
