In this section, you will learn about Hibernate datasource configuration in Tomcat.

For Hibernate datasource configuration in Tomcat, you will need to take care the following things :

• There will be no change in your hibernate.cfg.xml file.
  
  
• Also the will be no change in web.xml and your <resource-ref> will be same as previous :

<resource-ref>
<description>My DataSource</description>
<res-ref-name>jdbc/primaryDB</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<res-auth>Container</res-auth>
</resource-ref>

• You need to edit context.xml situated inside $CATALINA_HOME/conf directory add the following Resource entry inside <context>:

<Resource name="jdbc/primaryDB" auth="Container" type="javax.sql.DataSource"
maxActive="100" maxIdle="30" maxWait="10000"
username="yourusername" password="yourpassword" driverClassName="com.mysql.jdbc.Driver"
url="jdbc:mysql://localhost:3306/yourdatabase"/>

• The resource name in the context.xml must match your reference name in the web.xml. This configuration tell to < em>Tomcat environments about how to map resources from your deployment descriptor to the context.xml.
