With Hibernate 4.x you should use the same DTD as 3.x:
<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
<session-factory>
as you can see by this bug report, where the deprecation warning was removed.
Also the tutorials for 4.2 version use this, as you can see here.
The exception clearly says Caused by: org.xml.sax.SAXParseException; lineNumber: 2; columnNumber: 25; Document is invalid: no grammar found. at
which means that there is no baseline (define structure of the xml) to check your xml tags against.
You need to add the hibernate DOCTYPE, which is
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd" >
Also check is your xml well formed, look for any unclosed tags, etc...
This is related to hibernate.cfg.xml. For hibernate 4.3.0 Final also should use dtd as shown below to resolve this error.
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd" >
It is working after adding below
<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">

I am new to Hibernate, As per my knowledge, when hbm2ddl.auto is set to 'update', it should create a table if its doesn't exist, it should create a new column automatically if the new 'property' tag for column is added in mapping file. Right?
But whenever i am trying to run my class, it is throwing "Table or view doesn't exist" instead of creating it. I am using hibernate v5.10
Here's my POC example i am trying to run. Thanks in advance.

For anyone still searching for an answer, If you want to experience all the functionalities of "update" property like auto table creation, auto adding of columns (both case : if already not available), then go for the 5.0.1.Final version, it is the most stable version supporting them.
I think you need "create", "update" will only update existing tables, see docs:
https://docs.jboss.org/hibernate/orm/5.0/manual/en-US/html/ch03.html
I´m trying to create a MySQL database table by using hibernate but I get this error message:

Thank you for your help
I faced the same issue. It turns out that system is not able to access the hibernate-configuration-3.0.dtd from the url provided.
<DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">
So, I referenced it from the local system.
<!DOCTYPE hibernate-configuration SYSTEM
"classpath://org/hibernate/hibernate-configuration-3.0.dtd">
Worked well for me. Hope it helps!
cleared the space at the begining of hibernate.cfg.xml file. lt worked
<?xml version="1.0" encoding="UTF-8"?>
You need to close the tag <hibernate-configuration.
<hibernate-configuration>
There is not the ! character in the DOCTYPE:
<DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">
Should be
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">
The issue for me was the lack of HTTPS.
<!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN" "http://www.hibernate.org/dtd/hibernate-config">
I changed to:
<!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN" "https://www.hibernate.org/dtd/hibernate-config">
That fixed the issue.
I'm trying to implement a basic Hibernate example but I can't get it to work.
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.Transaction;
import org.hibernate.cfg.Configuration;
public class SimpleTest {
public static void main(String[] args) {
SessionFactory sessionFactory = new Configuration().
configure().buildSessionFactory();
Session session = sessionFactory.getCurrentSession();
Transaction tx = session.beginTransaction();
Lecturer lecturer1 = new Lecturer();
lecturer1.setFirstName("Fatma");
lecturer1.setLastName("Meawad");
session.save(lecturer1);
tx.commit();
System.out.println
("The lecturer " + lecturer1.getFirstName()+ " "
+ lecturer1.getLastName()+" is successfully added to your database");
}
}
Everytime I try to run it I get:

What can be the error any help??
Try changing the DOCTYPE to this:
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">
<!DOCTYPE hibernate-configuration SYSTEM
"classpath://org/hibernate/hibernate-configuration-3.0.dtd">
This means that hibernate will load the DTD from classpath - it is usually included in hibernate jar in org/hibernate directory.
However, we use hibernate 3.5.6 - I don't hnow if this approach still works in the newer version - give it a try. The benefit of this is that you are completely independent on internet connection, proxies and so on.
Hibernate Configuration File Location
The first solution was to provide the DTD file location in the system using classpath. So the DocType that worked offline would be;
<!DOCTYPE hibernate-configuration SYSTEM
"classpath://org/hibernate/hibernate-configuration-3.0.dtd">
Use SourceForge DTD URL with SYSTEM
Another solution I found working is when I change the DTD URL to SourceForge and changed the declaration from PUBLIC to SYSTEM.
So below will also work if your system is offline.
<!DOCTYPE hibernate-configuration SYSTEM
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

this is the basic steps that need to be followed while developing hibernate application ( am telling you from the basic level)
Steps To Create Hibernate Prog
Create Project
Create package inside the project (This is what I think You have missed (it is mandatory) - Ex: package in.myproject.test)
Create POJO Classes, configuration and hbm files
And at last, write your Java application
Remember
Creating package is must
cfg.configure("hibernate.cfg.xml"); -- we supply configure method, the configuration file name when we give our own name to the configuration file ( Ex - "myConfiguration.cfg.xml" (or) "myConfig.xml" etc).
Even if you supply the default configuration file name i.e "hibernate.cfg.xml", still it is fine (but not recomended)
simply there was error in this
<mapping resource="/login.hbm.xml"></mapping>
i just converted it to this
<mapping resource="login.hbm.xml"></mapping>
and it worked,besides this there were minor errors in field name property of login.hbm.xml which i sorted out by simply changing the names as they were on mysql table name.
