You should enable Spring transaction manager by adding @EnableTransactionManagement annotation to your context configuration class.

Since both services have @Transactional annotation and default value property of it is TxType.Required, current transaction will be shared among the services, provided that transaction manager is on. Thus a session should be available, and you won't be getting LazyInitializationException.
