Transaction required exception JPA / Spring

I have a method in the repository class marked as @Transactional, the aspect is being executed as seen in the stacktrace, but the exception being thrown is "Transaction required exception"

I changed the @Repository annotation to @Component (and it seemd like it fixed this problem in some situations), but it is still happening on the web role.

Here is the stacktrace:

2015-04-13 08:00:56,497 [http-nio-8080-exec-9] WARN  es.mycompany.util.filters.MyFilter - Error storing : /admin/online/update
org.springframework.dao.InvalidDataAccessApiUsageException: Executing an update/delete query; nested exception is javax.persistence.TransactionRequiredException: Executing an update/delete query

        at es.mycompany.dao.MyDAO.updateLastUpdatedTs(MyDAO.java:31)

And here is the code throwing the exception:

    @Transactional
    public void updateLastUpdatedTs(String id, Calendar date) {
        Query query = entityManager.createQuery("update MyEntity set lastUpdatedTs = :ts "
                + " where id= :id");
        query.setParameter("ts", date);
        query.setParameter("id", id);
        query.executeUpdate();
    }

Transactional annotation comes from org.springframework.transaction.annotation.Transactional

Versions:

Spring: 4.1.5.RELEASE 
Hibernate: 4.3.8.Final 
Aspectj: 1.8.5 
Tomcat 8.0.20

Configurations:

EMF:

<bean class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean"
        id="entityManagerFactory">
        <property name="persistenceUnitName" value="athena" />
        <property name="dataSource" ref="dataSource" />
        <property name="jpaDialect">
            <bean class="org.springframework.orm.jpa.vendor.HibernateJpaDialect"/>
        </property>
    </bean>

Transactions:

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

    <tx:annotation-driven mode="aspectj" transaction-manager="transactionManager" />

I am going truly nuts with this, any help would be great. I am currently trying switching to javax.transaction.Transactional; just in case.

As a note, this all works perfectly fine on my development environment (Windows, Idea Tomcat 8, JDK 8.0.31 (Oracle's), but it raises this error on Amazon EC2 Elasticbeanstalk (Tomcat 8, 64bit Amazon Linux 2015.03, Open JDK 8.0.31 (Tried to use 8.0.40 from Oracle as well)
