Spring data jpa + Spring Transaction for multiple database - spring

Question

I am implementing multiple transaction(database) for my service using spring data jpa with #Transaction, having two persistent Unit names. And deploying in Jboss 6.4 EAP
spring xml includes

Below are my service details
#Named(ServerConstants.SERVICE_DRAG_DROP)
**#Transactional("demoappmeta")**
public class DragDropService {
private static final Logger LOG = LoggerFactory.getLoggerFactory().getDomainLogger(ServerConstants.LOGGER_DOMAIN, DragDropService.class.toString());
#Inject
private TbAsmiDragDropRepository dragDropRepo;
public void createDragDrop(Message pMessage){
JSONObject requestJson = pMessage.getRequestObject().getRequestJson();
LOG.debug("inside createDragDrop() - Request : "+requestJson);
In Jboss I am unable to deploy it, I get the following exception:
Caused by: org.springframework.beans.factory.BeanCreationException:
Could not autowire field: private
com.test.demo.domain.repository.TbAsmiDragDropRepository
com.test.demo.domain.service.DragDropService.dragDropRepo; nested
exception is org.springframework.beans.factory.BeanCreationException:
Error creating bean with name 'tbAsmiDragDropRepository': Invocation
of init method failed; nested exception is
java.lang.IllegalArgumentException: Not an managed type: class
com.test.demo.domain.entity.TbAsmiDragDrop
If anything is missing or something is wrong, please advise

I found the solution just we have to set the attribute entity-manager-factory-ref="entitymanagerfactoryrefname" in
<jpa:repositories base-package="com.test.demo.domain.repository" entity-manager-factory-ref="entitymanagerfactoryrefname" />
