Answer

       <bean id=\"propertyConfigurer\" class=\"org.springframework.beans. factory.config.PropertyPlaceholderConfigurer\">

            <property name=\"location\"><value>datasource.properties</value></property>

        </bean>

        <bean id=\"dataSource\" class=\"org.springframework.jdbc.datasource.DriverManagerDataSource\">

            <property name=\"url\"><value>${database.url}</value></property>

            <property name=\"driverClassName\"><value>${database.driver}</value></property>

            <property name=\"username\"><value>${database.user}</value></property>

            <property name=\"password\"><value>${database.password}</value></property>

        </bean>

      

datasource.properties should contain the following entries: -

                database.url=jdbc:hsqldb:mydb

                   database.driver=org.hsqldb.jdbcDriver

                   database.user=hsql

                   database.password=password

        <bean id=\"myDataSource\" class=\"org.springframework.jndi.JndiObjectFactoryBean\">

            <property name=\"jndiName\" value=\"jdbc/myDataSource\" />

        </bean>
