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


Harry Metske commented on JSPWIKI-376:

Log4j has them (I actually did some tests with it today, and registered all Log4j MBeans to
the MBeanServer, and then dynamically adjusted the debuglevels with a jconsole, works perfect).
However, you cannot do this without bypassing the slf4j facade, and so you lose the independence
of the underlying logsystem.
I don't know if the other logger implementations offer these nice MBeans, but it should be
possible to offer these in slf4j and depending on the underlying logging system we should
get MBean access or not.

> 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).
