appContext.xml for transactionManager

[E. J. Fuhr]

here's how i set up hibernate to use persistence.xml with a transactionManager for tomcat. Is there a simpler way? the info in persistence.xml repeats this. isn't this redundant?

    <tx:annotation-driven />
    <tx:jta-transaction-manager />
    <bean class="org.springframework.orm.jpa.support.PersistenceAnnotationBeanPostProcessor" />
    <bean id="myDao" class="my.named.Dao"/>

    <bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
        <property name="dataSource" ref="dataSource"/>
        <property name="persistenceUnitName" value="jpQuestPU"/>
        <property name="jpaVendorAdapter">
            <bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter">
                <property name="showSql" value="true"/>
                <property name="generateDdl" value="true"/>
            </bean>
        </property>
    </bean>
    <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
        <property name="driverClassName" value="com.mysql.jdbc.Driver"/>
        <property name="url" value="jdbc:mysql://localhost:3306/MYDBASE"/>
        <property name="username" value="NAME"/>
        <property name="password" value="PWD"/>
    </bean>

    <bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager">
        <property name="entityManagerFactory" ref="entityManagerFactory"/>
        <property name="dataSource" ref="dataSource"/>
    </bean>
