Could not obtain transaction-synchronized Session for current thread

I am getting the following Exception with a Spring4/Hibernate4 project I converted from xml- to Java-Config. 

org.hibernate.HibernateException: Could not obtain transaction-synchronized Session for current thread

The project starts up property and errorfree in Eclipse, but on the first request the Exception appears. In my ConfigRoot-class I have @Bean configured for DataSource, SessionFactory, HibernateTransactionManager, ImprovedNamingStrategy.

All my @Service services are annotated with @Transactional.

Any idea where this could come from ?

As requested, here the stacktrace:

Edit 2

Strangely, I borrowed the whole Java-Config code from another project which works flawlessly, certainly I missed a detail. That's why I am not considering Some transaction propagations not working with Spring/Hibernate 4.

Such scenario:

Use this Thumb Rule :

1) For Every @Entity @Table(name = "Table1")

Create corresponding Services, and Corresponding DAO.

Just found it ... @EnableTransactionManagement was missing on my root configuration class.

Thanks everybody for the guidance.

I presume it is a problem of transactional proxy not being used (just a guess from the stacktrace). By default, spring uses a Jdk proxy for it, but that needs the service to be imported as an interface in the controller.

If it is the case, create an interface IPersonService containing relevant method from PersonService and import it in PersonController as @Autowired IPersonService personService; or even better, rename PersonService to PersonServiceImpl and make PersonService an interface.

And ... consistently do that for all your transactional services ...
