SPring wll not inject EntityMAnager into my DAO

[davidrocks]

I am quite new to Spring and have been given the task of refactoring an existing application and this time using spring. The application is struts hibernate and the basic architecture is

action -> service -> DAO -> Persistant Objects

I have managed to get the services injecting into the action and the DAO injecting into the service but the EntityMAnager is not being injected into the DAO.

THE DAO has a superclass...

public class HibernateGenericManager<T>  {

    protected Class<T> persistClass;

       @PersistenceContext
    protected EntityManager entityManager;
    public HibernateGenericManager() {
        this.persistClass = (Class<T>)((ParameterizedType)this.getClass()
            .getGenericSuperclass()).getActualTypeArguments()[0];
        
    }

    public void setEntityManager(EntityManager entityManager) {
        this.entityManager = entityManager ;
} 

Where I would expect the setEntityManager to be called.

THIs is part of my applicationContext

    <bean id="entityManagerFactory"
        class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
        <property name="dataSource" ref="dataSource" />
        <property name="jpaVendorAdapter">
            <bean
                class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter">
                <property name="database" value="MYSQL" />
                <property name="showSql" 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://127.0.0.1/football" />
        <property name="username" value="root" />
        <property name="password" value="&&&&&" />
    </bean>

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

and my persistence.xml

<persistence xmlns="http://java.sun.com/xml/ns/persistence"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd"
    version="1.0">
    <persistence-unit name="punit">
    </persistence-unit>
</persistence> 

Does anything seem wrong?

Many thanks in advance.

Please post definition of your DAOs in the application context xml.
