Transaction Management

The tomcat connection pooled datasource is registered with spring managed transaction manager in the persistence_postgres.xml

<tx:annotation-driven transaction-manager="openSRPTransactionManager" />

<bean id="openSRPTransactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">

    <property name="dataSource" ref="openSRPDataSource" />

</bean>

Spring transaction management can be used to define transactions

To define a method or class as having a transaction or part of a transaction simply annotate the method with @Transactional annotation.
