Hi there Wouldn't it make sense to use a BasicDataSource instead of DriverManagerDataSource as it is also recommended from Spring: http://docs.spring.io/spring/docs/current/spring-framework-reference/html/jdbc.html#jdbc-connections
Instead of this: <bean id="localDataSource" class="org.springframework.jdbc.datasource.IsolationLevelDataSourceAdapter"> <property name="targetDataSource"> <bean class="org.springframework.jdbc.datasource.DriverManagerDataSource"> <property name="driverClassName" value="${jpa.driverClassName}"/> <property name="url" value="${jpa.url}"/> <property name="username" value="${jpa.username}"/> <property name="password" value="${jpa.password}"/> </bean> </property> <property name="isolationLevelName" value="ISOLATION_READ_COMMITTED"/> </bean> we can configure this bean: <bean id="localDataSource" class="org.springframework.jdbc.datasource.IsolationLevelDataSourceAdapter"> <property name="targetDataSource"> <bean class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close"> <property name="driverClassName" value="${jpa.driverClassName}"/> <property name="url" value="${jpa.url}"/> <property name="username" value="${jpa.username}"/> <property name="password" value="${jpa.password}"/> </bean> </property> <property name="isolationLevelName" value="ISOLATION_READ_COMMITTED"/> </bean> Thanks Oli
