[jira] [Commented] (LOG4J2-293) classloader URI scheme broken or insufficient when using Log4jContextListener

    [ https://issues.apache.org/jira/browse/LOG4J2-293?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13701699#comment-13701699 ] 

Nick Williams commented on LOG4J2-293:
--------------------------------------

Can you provide a bit more information about the problem you're seeing? I'm unable to see a problem. Can you provide some example configurations, list directory/file layouts, show your deployment descriptor (web.xml), etc?

Note that the entire web initialization system got a major overhaul for 2.0-beta8, which comes out next week. See LOG4J2-270.

> I'm trying to migrate to Log4j2, and things looked promising when I spotted Log4jContextListener.
> However, there are too many holes.
> Firstly, I tried using classpath: as a scheme, and nothing blew up, so I assumed I'd got it right.
> Then I *looked at the code* (which shouldn't be how we find out) and eventually discovered some code relating to a 'classloader' scheme.
> Still silent failure.  It seems that the classpath is not being searched, perhaps just the WAR classloader, not the JARs in WEB-INF/lib.
> Next I tried omitting the / (i.e. using classloader:log4j2.xml) and got a NullPointerException.
> Can you please document what schemes are supported and what you expect them to do, and *not fail silently* when a configuration file is specified, but nothing happens.
