Hi all,

I am new to Hibernate (3.1.2). I can't seem to persist object to MySQL 5.0.18 NT db . However, Hibernate is able to load objects from the db, but does not seem to inserting anything. Any help would be appreciated.

Thanks
sundarvc

Here are the details:

Hibernate version: 3.1.2

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 package="home.ch02">
<class name="Test" table="my_test_table">
<id name="id" column="id" type="long" >
<generator class="increment"/>
</id>
<property name="name" column="name" type="string" length="20" />
</class>
</hibernate-mapping>


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

Session session = factory.openSession();
Test test = (Test) session.load(Test.class,new Long(1));
System.out.println(test.getName());
Test test2 = new Test();
test2.setName("Chakravarthy");
session.saveOrUpdate(test2);
session.flush();
session.close();

Full stack trace of any exception that occurs:

Name and version of the database you are using:

MySql 5.0.18 NT
