Answer 1

Just throw any RuntimeException from a method marked as @Transactional.

By default all RuntimeExceptions rollback transaction whereas checked exceptions don't. This is an EJB legacy. You can configure this by using rollbackFor() and noRollbackFor() annotation parameters:

@Transactional(rollbackFor=Exception.class)

This will rollback transaction after throwing any exception.
