spring transaction and aop - spring

Question

I'm writing a simple application with spring, I defined my daos and services with spring annotations and defined hibernate as the orm and transaction manager like this:
<bean id="dataSource" class="org.apache.tomcat.jdbc.pool.DataSource"
destroy-method="close" p:driverClassName="${jdbc.driverClassName}"
p:url="${jdbc.databaseurl}" p:username="${jdbc.username}" p:password="${jdbc.password}" />
<bean id="sessionFactory"
class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
<property name="dataSource" ref="dataSource" />
<property name="configLocation">
<value>classpath:env/hibernate.cfg.xml</value>
</property>
<property name="packagesToScan">
<list>
<value>com.skyfence.management.cm.model</value>
</list>
</property>
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">${jdbc.dialect}</prop>
<prop key="hibernate.show_sql">true</prop>
<prop key="hibernate.hbm2ddl.auto">create</prop>
</props>
</property>
</bean>
<tx:annotation-driven />
<bean id="transactionManager"
class="org.springframework.orm.hibernate4.HibernateTransactionManager">
<property name="sessionFactory" ref="sessionFactory" />
</bean>
like you can see I'm using annotations for the transactions management,
Until this point everything works fine.
Then I added a Logger Aspect to add log4j printouts before and after every method so I added the following to my applicationContext.xml
<aop:aspectj-autoproxy />
and created a new annotated aspect class:
#Aspect
#Component
public class LoggingAspect
{
}
The problem is that from that point hibernate is no longer working and I'm getting the following exception:
org.hibernate.HibernateException: No Session found for current thread
I suspect that somehow by adding the aspect the transactions stopped working but I have no idea how to solve it
Any help will be appreciated,
