I would stick to using the ContextManager interface rather than referencing the
implementation directly. That way you
code will continue to work even if the implementation or factory classes change.
For example, what would happen if the 'this.manager.lookup(ContextManager.ROLE)' call
passes back another
implementation of ContextManager? Your code will fall over. Mine won't.
You are ignoring one of the fundamental rules of OO. Do so at your own peril.
Paul.
