[slf4j-user] How to specify location of file to write log message to?

[Chris Pratt]

SLF4j is a Logging Facade, not a logging engine.  So... SLF4j doesn't
actually write out any files.  You need to configure the output file in
your Logging Engine (Log4j, Logback, etc).

Same with setDebugEnabled, since SLF4j is simply a common interface that is
applied to a wide variety of logging engines, it provides the common
facilities (i.e. Least Common Denominator) that are commonly used in
applications that require logging.  If you need something specific to your
logging engine, or something less common, you'll have to use the features
that are part of your chosen engine.
