See http://slf4j.org/faq.html.
SLF4J is only a facade, meaning that it does not provide a complete logging solution. Operations such as configuring appenders or setting logging levels cannot be performed with SLF4J.
slf4j-simple doesn't provide extra configuration features at all.
For other implementations you should use the way to configure they provide.
For example, log4j.properties for slf4j-log4j. See http://logging.apache.org/log4j/1.2/manual.html#Configuration.
