In the previous section we completed the database setup and created required table and populated with the data. In this section we will write required hibernate configuration files.<\/P>
\n

For this tutorial we need following Hibernate configuration files:<\/B><\/P>
\n

Hibernate Configuration File<\/B><\/P>
\n

Hibernate configuration file (hibernate.cfg.xml) is used to provide the information which is necessary for making database connections. The mapping details for mapping the domain objects to the database tables are also a part of Hibernate configuration file. <\/P>

Here is the code of our Hibernate Configuration File:<\/P>
