[jboss-jira] [JBoss JIRA] Commented: (AS7-1389) Log API dependencies should be included automatically in deployments

[David Lloyd (JIRA)]

    [ https://issues.jboss.org/browse/AS7-1389?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12615961#comment-12615961 ] 

David Lloyd commented on AS7-1389:
----------------------------------

99% of the time I think the user wants to have centrally configured logging, in which case the deployment should use our APIs and just ignore whatever is packaged with the application whether it was included intentionally or not.  As it is right now if people include logging JARs it's hard to say exactly what will happen - sometimes nothing is logged (for example if the slf4j API is bundled with no impl and the no-op logger is selected), sometimes the app will have separate logging (if it uses log4j and they bundle their own), sometimes it will use container logging (if they do not bundle anything, or if they include their own slf4j API but use Dependency: or another mechanism to get our impl).

I'd rather require that users include the JARs *and* specify the dependency exclusion if they want to do their own logging outside of the container.  Otherwise all logging should always go through the container just for consistency if nothing else.

> The following log APIs should be included by deployments by default:
> * {{org.slf4j}}
> * {{org.apache.commons.logging}}
> * {{org.log4j}}
> These dependencies should override the deployment's versions of these libraries unless explicitly excluded by {{jboss-deployment-structure.xml}}.
