Whenever I execute the Main.java file below I get this following error
"org.hibernate.exception.SQLGrammarException: could not fetch initial value for increment generator"
Main.java:
Code:
public class Main {
public void createResonsibilities(){
SessionFactory sessionfactory = NewHibernateUtil.getSessionFactory();
Transaction transaction = null;
try {
Session session = sessionfactory.openSession();
transaction = session.beginTransaction();
responsibilities responsibilityOne=new responsibilities("Java");
responsibilities responsibilityTwo=new responsibilities("SQL");
responsibilities responsibilityThree=new responsibilities("Oracle");
session.save(responsibilityOne);
session.save(responsibilityTwo);
session.save(responsibilityThree);
transaction.commit();
} catch (HibernateException e) {
transaction.rollback();
e.printStackTrace();
}
}
public static void main(String[] args) {
Main main=new Main();
main.createResonsibilities();
}
My hibernate.cfg.xml has the property <property name="hibernate.hbm2ddl.auto">update</property>
So even though the table does not exist in the database it should get created I assume
This my complete error log

Caused by: com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: Table 'revision.responsibilities' doesn't exist
this is my responsibility.hbm.xml:
Code:
<hibernate-mapping>
<class name="contacts.responsibilities" table="responsibilities">
<meta attribute="class-description">
</meta>
<id column="responsibilityId" name="responsibilityId" type="long">
<generator class="increment"/>
</id>
<property column="responsibilityName" name="responsibilityName" type="string"/>
