I am missing something (getting a null pointer for the entityManager)

The spring entry point, web.xml

Java Code:

<web-app version="2.4" xmlns="http://ift.tt/qzwahU"
         xmlns:xsi="http://ift.tt/ra1lAU"
         xsi:schemaLocation="http://ift.tt/qzwahU http://ift.tt/16hRdKA">

    <display-name>score progress</display-name>
   <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:spring.xml</param-value>
    </context-param>

        
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>
        
        <filter>
                <filter-name>struts2</filter-name>
                <filter-class>
                org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter
        </filter-class>
        </filter>
        
        <filter-mapping>
                <filter-name>struts2</filter-name>
                <url-pattern>/*</url-pattern>
        </filter-mapping>
        
        <welcome-file-list>
        <welcome-file>index.jsp</welcome-file>
    </welcome-file-list>
        
</web-app>

The mayor spring.xml (after resolving I will split this file into two)

Java Code:

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://ift.tt/GArMu6"
       xmlns:xsi="http://ift.tt/ra1lAU"
       xmlns:aop="http://ift.tt/OpNdV1"
       xmlns:context="http://ift.tt/GArMu7"
       xmlns:tx="http://ift.tt/OGfeU2"
       xmlns:jee="http://ift.tt/OpNaZ5"
       
       xsi:schemaLocation="http://ift.tt/GArMu6

           http://ift.tt/1j5lSTg"
                default-lazy-init="true" default-autowire="byName">
        
                <context:component-scan base-package="com.canteratech.scoreprogress" />
                <bean id="txManager" class="org.springframework.orm.jpa.JpaTransactionManager" />
        <!--  
        <import resource="classpath:scoreprogress-spring-core.xml" />
        <import resource="scoreprogress-spring/jpa.xml" />
        -->
        
        <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/scoreprogress"/>
            <property name="username" value="root"/>
            <property name="password" value=""/>
        </bean>

    <bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
                <property name="dataSource" ref="dataSource"/>
                <!-- 
                <property name="persistenceUnitName" value="scoreprogress-jpa"/>
                 -->
                <property name="jpaDialect">
                        <bean class="org.springframework.orm.jpa.vendor.HibernateJpaDialect" />
                </property>
                <property name="jpaVendorAdapter">
                                <bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter" />
                </property>
                <property name="packagesToScan" value="com.canteratech.scoreprogress" />
                <property name="jpaProperties">
                <props>
                                <prop key="hibernate.dialect">org.hibernate.dialect.MySQL5InnoDBDialect</prop>
                        </props>
                </property>
        </bean>
    
        <tx:annotation-driven/>
        <!-- 
        <tx:annotation-driven transaction-manager="transactionManager" />
         -->
    <bean id="persistenceAnnotation" class="org.springframework.orm.jpa.support.PersistenceAnnotationBeanPostProcessor" />
        
        <bean id="entityManager" class="org.springframework.orm.jpa.support.SharedEntityManagerBean">
    <property name="entityManagerFactory" ref="entityManagerFactory"/>
    
</bean>
</beans>

and finally the entityManger injection (which turns out to be null)

Java Code:

@Component(value = "userDao")
public class UserDaoImpl implements UserDao {
        
        //@Autowired
        @PersistenceContext(name="dataSource")
    protected EntityManager entityManager;
        ….
