I cannot figure out how to properly configure transaction manager to be used with Wildfly and Hibernate. My configuration is:

<bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">      
<property name="dataSource" ref="dataSource"/> 
<property name="hibernateProperties"> 
     <!-- All properties provided by application server environment --> 
     <props> 
          <prop key="hibernate.dialect">org.hibernate.dialect.PostgreSQLDialect</prop>      
          <prop key="hibernate.hbm2ddl.auto">validate</prop> <!-- Second level cache configuration -->      
          <prop key="hibernate.cache.use_second_level_cache">false</prop>      
          <prop key="hibernate.cache.provider_class">net.sf.ehcache.hibernate.EhCacheProvider</prop>      
          <prop key="hibernate.generate_statistics">true</prop>      
          <prop key="hibernate.cache.use_structured_entries">true </prop>   
          <!-- Query cache -->    
          <prop key="hibernate.cache.use_query_cache">false</prop> 
          <prop key="hibernate.cache.region.factory_class">net.sf.ehcache.hibernate.EhCacheRegionFactory</prop>      
          <prop key="hibernate.cache.provider_configuration_file_resource_path"> "" </prop>      
          <prop key="jadira.usertype.autoRegisterUserTypes">true</prop> 
          <prop key="jadira.usertype.databaseZone">jvm</prop>      
          <prop key="jadira.usertype.javaZone">jvm</prop> 
          <prop key="hibernate.transaction.factory_class">org.hibernate.transaction.JTATransactionFactory</prop> 
          <prop key="hibernate.transaction.manager_lookup_class"> org.hibernate.transaction.JBossTransactionManagerLookup </prop> 
          <prop key="hibernate.transaction.jta.platform">jta</prop> 
     </props> 
</property> 
<property name="packagesToScan" value="org.example"/> 
</bean> 

<bean id="txManager" class="org.springframework.transaction.jta.JtaTransactionManager"> 
     <property name="allowCustomIsolationLevels" value="true"/> 
</bean>

what I would like to achieve is having a transactional service bean containing two other beans with database access, using the same transaction.

@Service("terminalQueryService") public class UserQueryServiceImpl implements UserQueryService {  
  
  @Transactional(readOnly = true, propagation = Propagation.REQUIRED) 
  public PaginatedList<PetDto> browse(PageDefinition pageDefinition, String userLogin) { 
     User user = null; 
     try { 
          user = userQueriesFacade.getUser(userLogin);      
     } catch (AuthorizationServiceException e) { return PaginatedList.getEmptyList(); } 
     PaginatedList<Pet> petListagedList = petQueriesFacade.browse( pageDefinition, user.getId());  
     List<PetDto> petDtoList = new ArrayList<>(); 
     List<Pet> petEntityList = petEntityPagedList.getList(); 
     dtoMapper.assembleDtos("petDtoKey", petDtoList, petEntityList); 
     return petEntityPagedList.transform(petDtoList); 
  } 
}

the query fasades look like:

@Cacheable("userForSecurity") 
@Transactional(propagation = Propagation.REQUIRED) 
public User getUser(PageDefinition pageDefinition, String login) {  
     User user = (User) getSession() .createQuery( "from User mu left outer join 
                         fetch mu.additionalPrivileges left outer join fetch mu.roles 
                         where mu.login = :login AND mu.status != :archivedStatus") 
                         .setParameter("login", login) 
                         .setParameter("archivedStatus", UserStatus.ARCHIVED) .uniqueResult(); 
     return user; 
}

the error I get is

WARN  [org.springframework.remoting.support.RemoteInvocationTraceInterceptor] (default task-38) Processing of HttpInvokerServiceExporter remote call 
resulted in fatal exception: org.example.logic.remote.services.user.UserQueryService.browse: 
org.hibernate.LazyInitializationException: could not initialize proxy - no Session

on the line that it trying to transforms dto what suggest me that session was closed.

if I remove @Transactional from fasades then (and leave it on the service) the first query executes without any problem, the second raises:

[org.springframework.remoting.support.RemoteInvocationTraceInterceptor] (default task-37) Processing of HttpInvokerServiceExporter remote call 
resulted in fatal exception: org.example.logic.remote.services.user.UserQueryService.browse: 
org.hibernate.HibernateException: Could not obtain transaction-synchronized Session for current thread
at org.springframework.orm.hibernate4.SpringSessionContext.currentSession(SpringSessionContext.java:134) 
at org.hibernate.internal.SessionFactoryImpl.getCurrentSession(SessionFactoryImpl.java:988)

any ideas?
