Answer 2

My controllers where initialized twice, the same config was used by the root ApplicationContext and by the FrameworkServlet. I've had two contexts initialized. I've created a config for the root context named springapp.xml and moved all my middle tier configuration there and left my web tier configuration in springapp-servlet.xml

My web.xml now looks like this and everything works fine:

      <context-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>
                /WEB-INF/springapp.xml
        </param-value>
        </context-param>

     <listener>
            <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
        </listener>

<filter>
      <filter-name>hibernateFilter</filter-name>
      <filter-class>org.springframework.orm.hibernate4.support.OpenSessionInViewFilter</filter-class>
      <init-param>
         <param-name>sessionFactoryBeanName</param-name>
         <param-value>sessionFactory</param-value>         
      </init-param>      
   </filter>
