问题 I am using log4j xml configuration for my project, NOT log4j.properties file. I am trying to display debug messages in eclipse console. But it didn't worked out.

问题 I having an application with multi-tenancy support, that is one server and multiple DB, there will be separate DB for each tenant.

问题 I've using SLF4j as my logging framework, backed by log4j. My problem is that I am looking for a way to change the logging level for my logger at runtime.
