How to "install" AS3Commons Logging in Flash?

Hi im pretty new to flash so sorry if the question is stupid, but i just can´t get the as3commons logger to run.

What i did:

package {    
    import org.as3commons.logging.ILogger;
    import org.as3commons.logging.LoggerFactory;

        public class "classname" {
            var logger:ILogger = LoggerFactory.getLogger("myLog开发者_JS百科ger");

            public function "methodname"() {
                log.info("Some logging message");
            }
        }
    }

but i get the error:

VerifyError: Error #1014: Class org.as3commons.logging::ILogger was not found.

I guess i made some mistake in placing the swc file in my folder structure or something, i tried differnt things but neither worked for me. Has anybody a tutorial or can tell me how to make it run exactly?

Update:

Regarding http://arthropod.stopp.se/ it´s true that one can use it easily but i think it´s not too handy to have to start arthropod to see the traces.

Is there a possibility to see them in flash like a normal trace as well?

Not what you're looking for with that logger, but this one...is better and easier :)
