Java - Hibernate connection database

Question

I'am learning to use java since few weeks et i want to use Hibernate in simple Java console application. I download the last version of Hibernate ORM (4.3.8)

I add this Jars in my ClassPath :

• com.mysql.jdbc_5.1.5.jar
• sqlite-jdbc-3.8.7.jar
• Hibernate Library\antlr-2.7.7.jar
• Hibernate Library\dom4j-1.6.1.jar
• Hibernate Library\hibernate-commons-annotations-4.0.5.Final.jar
• Hibernate Library\hibernate-core-4.3.8.Final.jar
• Hibernate Library\hibernate-jpa-2.1-api-1.0.0.Final.jar
• Hibernate Library\jandex-1.1.0.Final.jar
• Hibernate Library\javassist-3.18.1-GA.jar
• Hibernate Library\jboss-logging-3.1.3.GA.jar
• Hibernate Library\jboss-logging-annotations-1.2.0.Beta1.jar
• Hibernate Library\jboss-transaction-api_1.2_spec-1.0.0.Final.jar

My Class :

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

@Entity
@Table(name = "STUDENT_INFORMATIONS")
public class Student_Info {

    @Id
    private int rollNo;

    private String name;


    public int getRollNo() {
        return rollNo;
    }
    public void setRollNo(int rollNo) {
        this.rollNo = rollNo;
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }

}

My Main Code :

    Student_Info student = new Student_Info();
    student.setName("Fabien");
    student.setRollNo(1);


    SessionFactory sessionFactory;
    ServiceRegistry serviceRegistry;

    Configuration configuration = new Configuration();
    configuration.configure();

    serviceRegistry = new StandardServiceRegistryBuilder().applySettings(
            configuration.getProperties()).build();
    sessionFactory = configuration.buildSessionFactory(serviceRegistry);

    Session session = sessionFactory.openSession();
    session.beginTransaction();

    session.save(student);

    session.getTransaction().commit();
    session.close();
    sessionFactory.close();

SQLite

First i create an hibernate.cfg.xml configuration for SQLite with dialect property to "util.SQLiteDialect"

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN" 
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

<hibernate-configuration>
        <session-factory>
                <property name="show_sql">true</property>
                <property name="format_sql">true</property>
                <property name="dialect">util.SQLiteDialect</property>
                <property name="connection.driver_class">org.sqlite.JDBC</property>
                <property name="connection.url">jdbc:sqlite:SQLiteJDBC.sqlite</property>
                <property name="connection.username"></property>
                <property name="connection.password"></property>

                <!--  create / update  -->
                <property name="hibernate.hbm2ddl.auto">create</property>

                <!--  Liste des classes à Mapper en base de données -->
                <!--  <mapping resource="User.hbm.xml"/> -->
                <mapping class="com.hibernate.Student_Info"/>
        </session-factory>
</hibernate-configuration>

When i run my main program i have this error :

MySql

After i tried with a mysql Database

<?xml version="1.0" encoding="utf-8"?>

1 - Do you know if is it possible to use hibernate on SQLite ?

2 - If yes, do you know why it doesn't works ?

3 - For MySql, what is the problem ?

thank you very much !!

Answer 1

Thanks to Todd for my Syntaxe Error (MySql).

For SQLite, the dialect is not present in hibernate 4.3. So i found and adapt a classe for use SQLite with Hibernate 4.3.8 :

/*

 * a legal notice, here is a blessing:

Answer 2

I think you might have just spelled "hibernate" wrong...

Caused by: com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: Unknown database 'hierbnate'

Try changing this:

<property name="hibernate.connection.url">jdbc:mysql://localhost:3306/hierbnate</property>

To this:

<property name="hibernate.connection.url">jdbc:mysql://localhost:3306/hibernate</property>

(Unless your db is really called hierbnate, and then I'll just delete this answer).
