Transactions on Spring 2.0

[viniciuscarvalho]

Hello there! I have a few questions regarding Transactions on Spring 2.0, hope you guys help me out.

1st. When using @Transactional attribute, I know annotations are not inherited, but we use templates here, so for example:

public class CrudService {
 @Transactional(propagation = Propagation.REQUIRED)
 public void save(T entity){...}
}

public class SpecialCrudService extends CrudService{
 @Transactional(propagation = Propagation.MANDATORY)
 //overridden method
 public void save(T entity){...}
}

}

Will the above work? Will spring respect the new transaction behavior for the new subclass?

2nd. Is it possible (inside a full jee container like JBoss, or using JOTM) to have JTA transactions that spam multiple resources (JMS and Databases for example)? Will Spring JTA transactions support deal within it? My architecture is based on ActiveMQ for the JMS and MDP

Best Regards

Why not? Set up correctly (JtaTransactionManger) there should be no problem. Any reason you put it into question?

Yes. Spring doesn't implement transaction capabilities, it just drives the transaction. This means that if your transaction manager can handle multiple datasources, Spring will drive the tx over all the datasources enlisted with the JTA TM.
