Subject Re: [Mailet API] Logging Proposal
Date Mon, 10 Jun 2002 22:14:10 GMT
I think there is still principal question which has to be addressed first.
The question is: will Mailet be Avalon dependant or not?
If Mailet is clean from Avalon then logging can be removed from Mailet API,
but if Mailets will be Avalonized then logging must (more precisely may) be
in API. Before this is decided no further speculations make sense.
I don't see anything against Avalonization of Mailets.
What is the bottom line of this discussion since James runs on the top of
Phoenix and Phoenix is on the top of Avalon? What is still not Avalonized in
James (like Mailet API) shall be Avalonized, or... whole James has to be
rewritten from ground up to keep it consistent with something else than
