Multiple transaction managers, no session found.

[mbrnwsk]

I need to have two transaction managers in my Spring application. I use them by annotating service classes by @Transactional("nameOfTxManager"). Howewer, I am only able to use one of them - when I call some method of service class annotated with second transaction manager, I get "org.hibernate.HibernateException: No Session found for current thread" exception. Here is some code that reflects problem:

1st service class:

@Transactional("txManagerHSQL")
public class LocalSynchroServiceImpl extends SynchroServiceImpl implements LocalSynchroService {

    public List<Synchro> findAll() {
        return getDaoAgent().getSynchroDao().findAllLocal();
    }
}

2nd service class

@Transactional("txManagerMySQL")
public class RemoteSynchroServiceImpl extends SynchroServiceImpl implements RemoteSynchroService {

    public List<Synchro> findAll() {
        return getDaoAgent().getSynchroDao().findAllRemote();
    }
}

Piece of configuration connected with transactions:

<tx:annotation-driven />
<bean id="txManagerHSQL" class="org.springframework.orm.hibernate4.HibernateTransactionManager">
     <property name="sessionFactory" ref="sessionFactoryHSQL"/>
</bean>
<bean id="txManagerMySQL" class="org.springframework.orm.hibernate4.HibernateTransactionManager">
     <property name="sessionFactory" ref="sessionFactoryMySQL"/>
</bean>

Exception:

org.hibernate.HibernateException: No Session found for current thread
    at org.springframework.orm.hibernate4.SpringSessionContext.currentSession(SpringSessionContext.java:97)
    at org.hibernate.internal.SessionFactoryImpl.getCurrentSession(SessionFactoryImpl.java:941)
    at pl.mbrnwsk.clientsRegister.dao.DaoImpl.getCurrentSession(DaoImpl.java:75)

The annotation of 2nd service class is interpreted correctly, because when I change name of transaction manager to some random name, I get the exception that such bean was not found. And also, when I set name as @Transactional("txManagerHSQL"), it works fine but with not the transaction manager I want.
