Each
persistent class needs to be mapped with
its configuration file. Following code
represents Hibernate mapping file for
AppLabsUser class.

<property column="USER_MODIFICATION_DATE"

One can also generate Hibernate mapping
documents using Hibernate extension toolset.
Hibernate mapping documents are straight
forward. The <class> element maps
a table with corresponding class. The
<id> element represents the primary
key column, and its associated attribute
in the domain object. The <property>
elements represent all other attributes
available in the domain object.
