Hi,
I am just novice to Hibernate.I am doing very simple example.Everything is working fine but database is not updated.I am just inserting records in the table.
java Bean file:Contact.java

Hibernate version:3.2

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>
<class name="com.oreilly.Contact" table="CONTACT">
<id name="id" type="integ" column="ID" >
<generator class="assigned"/>
</id>

<property name="firstName">
<column name="FIRSTNAME" />
</property>
<property name="lastName">
<column name="LASTNAME"/>
</property>
<property name="email">
<column name="EMAIL"/>
</property>
</class>
</hibernate-mapping>

:


Code between sessionFactory.openSession() and session.close()
Contact contact = new Contact();
contact.setId(3);
contact.setFirstName("Pranabesh");
contact.setLastName("Paul");
contact.setEmail("pranabesh.paul@wipro.com");
session.save(contact);
System.out.println("Done");
}catch(Exception e){
System.out.println("Exception is here"+e.getMessage());
}finally{
// Actual contact insertion will happen at this step
session.flush();
session.close();
System.out.println("Its over");
}
