Pick one logging library (ie, log4j). Add the "log to log4j from slf4j" jar. For all other logging libraries, add "log to slf4j from *" jars. It's pretty much that simple, although really badly designed logging libraries like java.util.logging may require extra steps or run poorly. > * having other libraries in the classpath with different versions of slf4j the slf4j api is pretty much backward compatible no matter what version you use, and jars don't inline slf4j. So you can just pick whatever version you like, generally the latest slf4j version available.
