The Logback ruby gem packages the Logback java log writer, and provides a JRuby facade for programmatic Logback setup. Logback implements the SLF4J SPI packaged in the slf4j gem.


require 'rjack-logback'
RJack::Logback.config_console( :level => :info )

log = RJack::SLF4J[ "my.app.logger" ]
log.info "Hello World!"
