In this section, you will learn about configuring hibernate to connect to database via JNDI datasource.

You need to do following thing to configure hibernate for connecting database via JNDI datasource :

• Need to specify your data source in context.xml file(Inside META-INF) :

<Context>
<Resource 
name="jdbc/AkWebAppDB" 
auth="Container" 
type="javax.sql.DataSource" 
username="ak" 
password="" 
driverClassName="org.h2.Driver" 
url="jdbc:h2:mem:target/test/db/h2/hibernate" 
maxActive="8" 
maxIdle="4"/>
</Context>	

• <resource-env-ref> inside web.xml which tells the container that you are using this resource :

<resource-env-ref>
<resource-env-ref-name>jdbc/AkWebAppDB</resource-env-ref-name>
<resource-env-ref-type>javax.sql.DataSource</resource-env-ref-type>
</resource-env-ref>

• persistence.xml situated inside META-INF :

<persistence-unit name="akwebapp">
<provider>org.hibernate.ejb.HibernatePersistence</provider>
<properties>
<property name="hibernate.dialect" value=




					"org.hibernate.dialect.H2Dialect" />
<property name="hibernate.connection.datasource" value="java:comp/env/jdbc/AkWebAppDB"/>
</properties>
</persistence-unit>
