Or you can use log4j via SLF4J: void *debug*(String <http://java.sun.com/j2se/1.5.0/docs/api/java/lang/String.html> format, Object <http://java.sun.com/j2se/1.5.0/docs/api/java/lang/Object.html> arg1, Object <http://java.sun.com/j2se/1.5.0/docs/api/java/lang/Object.html> arg2)
Log a message at the DEBUG level according to the specified format and arguments. This form avoids superfluous object creation when the logger is disabled for the DEBUG level. *Parameters:*format - the format stringarg1 - the first argumentarg2 - the second argument http://www.slf4j.org/api/org/slf4j/Logger.html#debug(java.lang.String,%20java.lang.Object,%20java.lang.Object) Maarten On Sun, Apr 6, 2008 at 10:46 PM, Jacob Kjome <[EMAIL PROTECTED]> wrote: > > How about LogMF or LogSF in Log4j's own "Extras" companion? > > http://logging.apache.org/log4j/companions/extras/index.html > > > http://logging.apache.org/log4j/companions/extras/apidocs/org/apache/log4j/LogMF.html > > http://logging.apache.org/log4j/companions/extras/apidocs/org/apache/log4j/LogSF.html > > > Jake > > > Wim Deblauwe wrote: > > > You probably mean that you want to avoid expensive string concatenation > > and > > toString() operations if you logging is not logged anyway.
