[jira] Commented: (SOLR-549) Enable configurable logging (jul or log4j)

["Ryan McKinley (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/SOLR-549?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12591672#action_12591672 ] 

Ryan McKinley commented on SOLR-549:
------------------------------------

This solves the "how do I use log4j in solr" problem, but I think it sends solr down the wrong path.  I really don't think we want to deal with configuring the logging internally.  That is what the logging frameworks are supposed to do for us!

Rather then taking this approach, I think we should just use SLF4J (http://www.slf4j.org/), it does what this patch does, but it is supported elsewhere and has more options ;)

> java.util.logging does not allow to easily create a self-sufficient 'war' with respect to logging configuration.
> The java.util.logging.LogManager used by the application is always created by the container and is thus only configurable through the container; furthermore, if one already uses say log4j in a webapp that embeds Solr, it does not even seem possible to re-route jul logging into log4j just by configuration.
