hibernate invalid configuration exception

Question

I am new to Hibernate. My Hibernate configuration file is as follows:

<?xml version='1.0' encoding='utf-8'?>
<hibernate-configuration
    xmlns="http://www.hibernate.org/xsd/hibernate-configuration"
    xsi:schemaLocation="http://www.hibernate.org/xsd/hibernate-configuration        hibernate-configuration-4.0.xsd"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">

    <session-factory>
        <!-- Database connection settings -->
        <property name="connection.driver_class">org.gjt.mm.mysql.Driver</property>
        <property name="connection.url">jdbc:mysql://localhost:3306/hibernate</property>
        <property name="connection.username">root</property>
        <property name="connection.password">QADEER</property>

        <!-- JDBC connection pool (use the built-in) -->
        <property name="connection.pool_size">1</property>

        <!-- SQL dialect -->
        <property name="dialect">org.hibernate.dialect.MySQLDialect</property>

        <!-- Enable Hibernate's automatic session context management -->
        <property name="current_session_context_class">thread</property>

        <!-- Disable the second-level cache  -->
        <property  name="cache.provider_class">org.hibernate.cache.internal.NoCacheProvider</property>

        <!-- Echo all executed SQL to stdout -->
        <property name="show_sql">true</property>

        <!-- Drop and re-create the database schema on startup -->
        <property name="hbm2ddl.auto">create</property>
        <mapping class="org.test.Person"/>
    </session-factory>
</hibernate-configuration>

I have the following Person.java class:

package org.test;

import javax.persistence.Entity;
import javax.persistence.Id;

@Entity
public class Person 
{
    @Id
    private int id;
    private String name;

    public int getId() {
        return id;
    }

    public String getName() {
        return name;
    }

    public void setId(int id) {
        this.id = id;
    }

    public void setName(String name) {
        this.name = name;
    }
}

Main class:

package org.test;

import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;

public class Main 
{
    public static void main(String args[])
    {
        Person obj=new Person();
        obj.setId(1);
        obj.setName("qadeer");

        @SuppressWarnings("deprecation")
        SessionFactory buildSessionFactory = new Configuration().configure().buildSessionFactory();
        Session session = buildSessionFactory.openSession();
        session.beginTransaction();
        session.save(obj);
        session.getTransaction().commit();
    }
}

when i run the code it give me following excwption.....

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">
