It is said that in the Spring javadoc article about DriverManagerDataSource class, that this class is very simple and that it is recommended

to use a JNDI DataSource provided by the container. Such a DataSource can be exposed as a DataSource bean in a Spring ApplicationContext via JndiObjectFactoryBean

The question is: how do I accomplish this?

For example, if I wish to have DataSource bean to access my custom MySQL database, what would I require then? What should I write in the context configuration, etc?

    If using Spring’s XML schema based configuration, setup in the Spring context like this:

    <beans xmlns="http://www.springframework.org/schema/beans"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xmlns:jee="http://www.springframework.org/schema/jee" xsi:schemaLocation="
    http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
    http://www.springframework.org/schema/jee http://www.springframework.org/schema/jee/spring-jee.xsd">
...
<jee:jndi-lookup id="dbDataSource"
   jndi-name="jdbc/DatabaseName"
   expected-type="javax.sql.DataSource" />

    Alternatively, setup using simple bean configuration like this:

    <bean id="DatabaseName" class="org.springframework.jndi.JndiObjectFactoryBean">
    <property name="jndiName" value="java:comp/env/jdbc/DatabaseName"/>
</bean>

    You can declare the JNDI resource in tomcat’s server.xml using something like this:

    <GlobalNamingResources>
    <Resource name="jdbc/DatabaseName"
              auth="Container"
              type="javax.sql.DataSource"
              username="dbUser"
              password="dbPassword"
              url="jdbc:postgresql://localhost/dbname"
              driverClassName="org.postgresql.Driver"
              initialSize="20"
              maxWaitMillis="15000"
              maxTotal="75"
              maxIdle="20"
              maxAge="7200000"
              testOnBorrow="true"
              validationQuery="select 1"
              />
</GlobalNamingResources>

    And reference the JNDI resource from Tomcat’s web context.xml like this:

      <ResourceLink name="jdbc/DatabaseName"
   global="jdbc/DatabaseName"
   type="javax.sql.DataSource"/>

    Reference documentation:

    Edit: This answer has been updated for Tomcat 8 and Spring 4. There have been a few property name changes for Tomcat’s default datasource resource pool setup.
