Hello Everyone,

I'm new to hibernate, I was able to set up Hibernate successfully as per the instructions in the tutorial on this site.

Now, instead of HSQL DB I'm using MySQL.

I'm able to connect to the database successfully with plain old JDBC as well as with Hibernate.

But, when I try to call a test method to store data into a table, I get
java.lang.ExceptionInInitializerError
com.forbes.finapps.util.HibernateUtil.<clinit>(HibernateUtil.java:22)

I did search on Google for possible solutions but didn't find any so far.

Any help is appreciated.

Hibernate version: 3.2.2

Mapping documents:
Code:
<?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>

        <!-- Database connection settings -->
        <property name="connection.driver_class">com.mysql.jdbc.Driver</property>

        <property name="connection.url">jdbc:mysql://192.168.1.xxx:3306/someapp</property>
        <property name="connection.username">someapp</property>
        <property name="connection.password">someapp</property>

        <!-- JDBC connection pool (use the built-in) -->
        <!-- TODO: Configure this for production -->
        <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.NoCacheProvider</property>

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

        <!--
        <property name="hbm2ddl.auto">update</property>
         -->
        <!-- Example -->
        <!--
        <mapping resource="events/Event.hbm.xml"/>
        -->
        <mapping resource="com/forbes/finapps/ibes/beans/identification/IbesIdentification.hbm.xml"/>
    </session-factory>

</hibernate-configuration>


Code between sessionFactory.openSession() and session.close():
Code:
        Session session = HibernateUtil.getSessionFactory().getCurrentSession();

        session.beginTransaction();

        IbesIdentification ibesIdentification;

        Iterator<IbesIdentification> it = ibesIdentificationList.iterator();

        while (it.hasNext()) {
            ibesIdentification = it.next();
            session.save(ibesIdentification);
        }

        session.getTransaction().commit();

There was some problem in the mapping file for the table.

I had to rename the <id field , from id to the actual Primary Key in the bean.

Because of the above problem with the id field HibernateUtil was unable to talk to the JavaBean using the map file for the bean.

Sorry I didn't realize that this was a problem.

[SOLVED]
