I am beginner and could not perform database insert.
everything else is mentioned below-

Hibernate version: - 3.0

Mapping documents:
<?xml version="1.0" ?>
<!DOCTYPE hibernate-mapping PUBLIC
"-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">

<hibernate-mapping>

<class name="com.mycompany.person.Person" table="PERSON" >
<id name="id" column="PERSON_ID" unsaved-value="id_value">
<generator class="native" />
</id>
<property name="personName" column="PERSON_NAME" type="string" />
<property name="addressLine1" column="ADDRESS_LINE_1" type="string" />
<property name="addressLine2" column="ADDRESS_LINE_2" type="string" />
<property name="addressCity" column="ADDRESS_CITY" type="string" />
<property name="addressState" column="ADDRESS_STATE" type="string" />
<property name="addressCountry" column="ADDRESS_COUNTRY" type="string" />
</class>

</hibernate-mapping>

Code between sessionFactory.openSession() and session.close():

Session session=HibernateUtil.getSessionFactory( ).getCurrentSession( );
session.beginTransaction( );

Person thePerson=new Person( );
thePerson.setPersonName( personName );
thePerson.setAddressLine1( addressLine1 );
thePerson.setAddressLine2( addressLine2 );
thePerson.setAddressCity( addressCity );
thePerson.setAddressState( addressState );
thePerson.setAddressCountry( addressCountry );

session.save( thePerson );
session.getTransaction( ).commit( );


Full stack trace of any exception that occurs:

Name and version of the database you are using:
MySQL -server 5.0

Hi!

See the following line in your stacktrace:



It looks like PERSON_ID does not get a value.

Just to debug this issue you might try another generator, f.x.
