Why do we use @Stateless when using @TransactionAttribute? EJB

I am wondering why do we use stateless annotation when using TransactionAttributeType, like so:

@TransactionAttribute(TransactionAttributeType.REQUIRES_NEW) 
@Stateless
public class Controller {

Any help is appreciated, thanks!

@Stateless determines the type of bean (one that does not maintain a conversational state with the client). @TransactionAttribute determines the way to handle transactions. In your example the bean won't hold client-specific state after the end of invocation. But when you choose REQUIRES_NEW it will always create a new transaction for each method invocation (in contrast to default REQUIRED when existing transaction can be used and if it doesn't exist it will be created by container).
