/**
|

* Convenience class that features simple methods for custom log4j configuration.
|
||||
*
|
||||
* <p>Only needed for non-default log4j initialization, for example with a custom
|
||||
* config location or a refresh interval. By default, log4j will simply read its
|
||||
* configuration from a "log4j.properties" or "log4j.xml" file in the root of
|
||||
* the classpath.
|
||||
*
|
||||
* <p>For web environments, the analogous Log4jWebConfigurer class can be found
|
||||
* in the web package, reading in its configuration from context-params in
|
||||
* {@code web.xml}. In a J2EE web application, log4j is usually set up
|
||||
* via Log4jConfigListener, delegating to Log4jWebConfigurer underneath.
