Why not change the lookup method to take an interface rather than a string
as a parameter.
So it would be
DataSourceComponent dataSource =
(DataSourceComponent)manager.lookup(DataSourceComponent.class);
That way not only do you get the idiom without adding the 'ROLE' member, but
also do a lookup for a role, and in Java one could argue Interface is Role.
What do you think ?
