Q5 answer :

Property file:

       <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

     Jndi:

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

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

        </bean>

Q6 answer:

<bean id="abstractTxDefinition" class="org.springframework.transaction.interceptor.TransactionProxyFactoryBean" lazy-init="true">

    <property name="transactionManager">

        <ref bean="transactionManager"/>

    </property>

    <property name="transactionAttributeSource">

        <ref bean="attributeSource"/>

    </property>

</bean>

<bean id="myService" parent="abstractTxDefinition">

    <property name="target">

        <bean class="com.mycompany.MyServiceImpl">
