Subject [jira] Commented: (JSPWIKI-376) Move from log4j to slf4j
Date Fri, 24 Oct 2008 16:33:44 GMT


Ceki Gulcu commented on JSPWIKI-376:


I would like to point out that dependencies on commons-logging can be replaced by jcl-over-slf4j
which is binary compatible with commons-logging 1.1.1 as well as 1.0.4. Such a move would
have all logging go through SLF4J instead of SLF4J *and* JCL. Moreover, users deploying on
Tomcat 5.5.x series would have much fewer problems when reloading JSPWiki.

Janne, if I could, I would discourage you from writing a facade for SLF4J which is a facade
in itself. 

Please ping me on mailing list if you need help regarding your planned migration.

> SLF4J allows far more flexible logging than log4j, and it would allow us to get rid of
these dumb log4j compatibility problems that sometimes occur.  It also plays better with other
applications, gives the user more power to choose how to log his stuff, and is also pretty
cool otherwise. The change would be relatively trivial, and would probably be largely invisible
to the users (since we could continue shipping with necessary log4j jars).
