[jboss-dev] Re: Something of interest to anyone who has to deal with java.util.logging vs. log4j vs. commons-logging vs. ....

[Scott M Stark]

I did the opposite and ported a number of the log4j appenders and 
configuration to jdk logging so that you essentially had the same 
configuration as the current log4j.xml and is in the common project:
https://svn.jboss.org/repos/common/common-logging-jdk/trunk/src/main/java/org/jboss/logging/jdk/

We talked about where to go with logging some here:
