Answer 1

The first code you present is for UserTransactions, i.e. the application has to do the transaction management. Usually you want the container to take care of that and use the @Transactional annotation. I think the problem in you case might be, that you have the annotation on a private method. I'd move the annotation to the class level

@Transactional
public class MyFacade {

public void databaseChanges() throws Exception {   
    A(); //update.
    B(); //insert
}

Then it should rollback properly. You can find more details here Does Spring @Transactional attribute work on a private method?
