Hibernate doesn't create table

I am using Hibernate and PostgresSQL and am trying to create a table by .xml with no success.
I don't see an error when I start Main.class. Maybe I should use another version of Hibernate?
I'm using Gradle and added in dependencies for the latest versions of hibernate-core, hibernate-entitymanager, and hibernate-validator.
I have been watching video published in 2016: maybe there's a problem in it.

Use below setting :

hibernate is giving me - "main" org.hibernate.MappingNotFoundException: resource: hibernate_hbm.xml.UserDetails.hbm.xml not found

I am working with hibernate. I create a table called UserDetails (POJO class) with id and name. I am however finding it difficult to execute the program because it is giving me this error -
Exception in thread "main" org.hibernate.MappingNotFoundException: resource:

As that file is on class path try the mapping resource value in hibernate.cfg.xml as below :
"classpath:UserDetails.hbm.xml"
<mapping resource="classpath:UserDetails.hbm.xml" />
Do share the folder structure that you followed as that'll help with the exact path to be used

hibernate MappingException:Unknown entity don't know why?

i have a problem and i need your help.i use eclipse 4.5.1. hibernate5.1
and here is the code
Exception in thread "main" org.hibernate.MappingException: Unknown entity: net.runze.hb1.entity.News
public class NewsManager {
public static void main(String[] args) throws Exception {
Configuration conf = new Configuration()
.configure();
ServiceRegistry serviceRegistry = new StandardServiceRegistryBuilder()
.applySettings(conf.getProperties()).build();
SessionFactory sf = conf.buildSessionFactory(serviceRegistry);
Session sess = sf.openSession();
Transaction ta = sess.beginTransaction();
News n = new News();
n.setTitle("Aliens");
n.setContent("hahahaha!");
sess.save(n); // here is where it threw exception
ta.commit();
sess.close();
sf.close();
}
}
and i use annotation to the entity class:
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.Table;
#Entity
#Table(name="news_inf")
public class News {
#Id
#GeneratedValue(strategy=GenerationType.IDENTITY)
private Integer id;
private String title;
private String content;
// getters and setters...
}
here is my hibernate.cfg.xml:

</hibernate-configuration>
they says this problem will happen when my #Entity import the wrong package,or the hibernate.cfg.xml forgot the "mapping". both them i made it right but it still don't work.

It is simply :)
Configuration conf = new Configuration()
.configure();
ServiceRegistry serviceRegistry = new StandardServiceRegistryBuilder()
.applySettings(conf.getProperties()).build();
SessionFactory sf = conf.buildSessionFactory(serviceRegistry);
Change to
SessionFactory sf = new Configuration().configure().buildSessionFactory();
Hibernate 5 :- org.hibernate.MappingException: Unknown entity

you have to specify where your configuration file is:
onfiguration conf = new Configuration().configure("[your package]/hibernate.cfg.xml");

Exception: The processing instruction target matching "[xX][mM][lL]" is not allowed

When I tried my first hibernate program and I got this error.
My program simply insert empID,first_name,second_name(table names) and using MySQL database.
Tried lot of solutions sill getting this error.

The problem with this lines
<property name="firstName" column="first_name" type="string">
<property name="lastName" column="second_name" type="string">
Should be
<property name="firstName" column="first_name" type="string" />
<property name="lastName" column="second_name" type="string" />
It would be more simply to find a solution if you show all stacktrace.
You can find examples of working with a configuration and a session here.
Upated
I check this mapping and it works fine. Looks like you have incorrect symbols (may be spaces) in the xml header. May be this will be helpfull Error: The processing instruction target matching “[xX][mM][lL]” is not allowed.

I googled out everything possible but i think i am overlooking some basic stuff.Any indication in right direction is appreciated! :)
One thing i considered is that if i have defined in class file NamedQueries, i do not need to mention it in xml file.Please correct me if i am wrong!

There are several issues here:
Your named queries should use entities not tables. If you want native queries you should use NamedNativeQuery instead.
You don't need to supply the entity name when fetching the query.
Change this:
Query query = session.getNamedQuery("hibernate_tut_emp.Employee.FindCountOfNames");
to:
Query query = session.getNamedQuery("FindCountOfNames");
