Subject Re: Question about the ContextAnchor class in log4j-core.
Date Mon, 14 Jul 2014 00:22:15 GMT
I'm just looking for a way to make this easier to use in async servlets.
I've been implementing some at work lately as an experimental way of
creating a REST facade for a JMS-based service, and having an easier method
to obtaining the right Logger would be nice.
