Hibernate In Servlet Example, Hibernate In Servlet Tutorial

With servlet, if we want to do some operations on the database, then we can also use hibernate ORM rather than JDBC.  We call this as servlet-Hibernate integration.

While integration servelt with hibernate, it is there to follow these setps

• In init() method of servlet, we need to create SessionFactory of hibernate, because SessionFactory is an heavy weight component, its the programmer responsibulity to make it as singleton, for this we need to create the object of SessionFactory in init() method of servelet
• Open a Session in service() method and perform the operations on the database close the Session in service()
• Close the SessionFactory of hibernate in destroy() method
• While integration servlet with hibernate, hibernate mapping files (.hbm.xml) and hibernate configure files(cfg.xml) need to be stored in classes folder only
• In the lib folder, we need to store all the jars related to hibernate and database
