Some error in hbm.xml file

I am new to hibernte. I was trying a simple retrieval of records from oracle table using hibernate.

My entity class is named pojo1 and pojo1.hbm.xml is as follows:

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

<hibernate-mapping package="hibernate" default-lazy="true">

<class name="pojo1" table="QUOTE_MESSAGE_TRANSLATION_BKP">
<meta attribute="class-description">
</meta>
<property name="id" column="TRANSLATION_ID" type="java.lang.Integer"/>
<property name="commitCode" column="COMMIT_CODE" type="java.lang.Integer"/>
</class>
</hibernate-mapping>

I am getting the following error while running the app class containing all the transaction code:

You have to declare an id for your entity class using <id> tag.

So change this:

<property name="id" column="TRANSLATION_ID" type="java.lang.Integer"/>

to this:

<id name="id" column="TRANSLATION_ID" type="int"></id>

You need an <id> or <composite-id> element inside your <class> element.

See the documentation here.

Mapped classes must declare the primary key column of the database table.
