Working with Spring Data JPA, Hibernate and multiple transaction manager: No bean named 'transactionManager' is defined

Question

EDIT: to whoever may be in interested in this issue, I provide the analysys of the problem with the related solution at the end of the question.

I am configuring a module for a web application in which I am using Spring 3.2, Hibernate 4.1, Spring Data JPA 1.3 and Apache CXF 2.5 (in particular the JAX-RS module). I have the following configuration (which is working perfectly fine, detailed are omitted for sake of conciseness):

  @Bean(name = "entityManagerFactory")
  public LocalContainerEntityManagerFactoryBean getEntityManagerFactory() throws SQLException{
    LocalContainerEntityManagerFactoryBean factory = new LocalContainerEntityManagerFactoryBean();
    //...    
    return factory;
  }

  @Bean(name = "transactionManager")
  public JpaTransactionManager getTransactionManager() throws SQLException{
    JpaTransactionManager manager = new JpaTransactionManager();
    //...    
    return manager;
  }

  @Bean(name = "persistenceExceptionTranslator")
  public PersistenceExceptionTranslator getPersistenceExceptionTranslator(){
    return new HibernateExceptionTranslator();
  }

My problem is that I have to rely on some external modules which define their own PlatformTransactionManager, so I find myself working with more transaction manager at the same time. This issue is easily addressed by Transactional.html#value(), so wherever I need to use @Transactional I qualified the annotation with the name of the transaction manager I have to use for that transaction.
I would like to change the name of the transaction manager I define in my module to something more meaningful, to meet the standard of the external modules. So, e.g., externalModule1 defines its manager as externalModule1TransactionManager and I would like to have

  @Bean(name = "myModuleransactionManager")
  public JpaTransactionManager getTransactionManager() throws SQLException{
    JpaTransactionManager manager = new JpaTransactionManager();
    //...    
    return manager;
  }

This seems pretty easy, unfortunately when I do this change (and I change the usage of @Transactional#value() accordingly I get an exception.

In particular, I would like to focus the attention on

myModule.package.SomeOtherClass.someOtherMethod(SomeClass.java:114)

and

myModule.package.SomeClass.someMethod(SomeClass.java:64)

Their codes look like

@Transactional("myModuleransactionManager")
public ... someOtherMethod(){
   ...
}

and

public ... someMethod(){
   ...
}

So, in my understanding this configuration should work, why does it throw that exception? Is a standard named transaction manager required? Or is it something due to cxf? I found some questions related to multiple transaction manager within the same application (example 1, example2) but the accepted answer in those questions drive to my solution. What did I misunderstand and I am doing wrong?
Thanks to everybody who is willing to read this long question till here!

EDIT to provide a complete explanation based on Michail's answer: using Spring Data JPA there is the need to define repositories interfaces to connect to the database. someOtherMethod is indeed calling one of my repositories which is defined as:

@Repository("myRepository")
@Transactional(propagation = Propagation.NESTED, value = "myModuleransactionManager")
public interface MyRepository extends JpaRepository<MyEntity, Integer>
{

}

This again looks fine, but looking at JpaRepository implementation source code (so, looking at org.springframework.data.jpa.repository.support.SimpleJpaRepository I discovered that the save (as well as other update methods) is annotated with @Transactional. Code from SimpleJpaRepository

    @Transactional
    public <S extends T> S save(S entity) {

        if (entityInformation.isNew(entity)) {
            em.persist(entity);
            return entity;
        } else {
            return em.merge(entity);
        }
    }

Therefore, when using Spring Data JPA the default transaction manager (the one named transactionManager) is mandatory. Bad for my goal, but at least I now know that's it!

Answer 1

Looks like your someOtherMethod calls any other @Transactional component (some class with save method). And I think it has @Transactinal() (empty) annotation (which uses default bean named transactionManager).

You may see 2 TransactionInterceptor positions in stacktrace. Please provide some details about it.
