Re: [castor-dev] Timestamp/Key idea

[Werner Guttmann]

Bruce,

just trying to address your concern whether to use Log4J or the Jakarta Commons Logging package. There's a quite
powerful xml publishing framework available at http://xml.apache.org named Cocoon. Now, Cocoon uses Jakarta
Commons Logging, and I know for sure that a user can EASILY change common logging features such as
thresholds to use, etc.

I hope this is of any help to you.

Werner
