2. Cause of Error

<bean id= "sessionfactory"          class= "Org.springframework.orm.hibernate4.LocalSessionFactoryBean" >          <property name= "DataSource" >                  <ref  parent= "DataSource"/>        </property>   </bean >

<ref/> with the Parent property, the correct configuration is <ref bean= "DataSource"/>

3. Solutions

<bean id= "sessionfactory"          class= "Org.springframework.orm.hibernate4.LocalSessionFactoryBean" >          <property name= "DataSource" >                  <ref  bean= "DataSource"/>        </property>   </bean >

Can ' t resolve reference to beans ' dataSource ' in parent Factory:no parent factory available
