[slf4j-user] Logging to file with slf4j.Logger. Where do log file go?

[Ceki Gulcu]

Hello Tom,

The following mailing list archives which are all mentioned in 
http://slf4j.org/mailing-lists.html are searchable:

http://news.gmane.org/gmane.comp.java.slf4j.user
http://marc.theaimsgroup.com/?l=slf4j-user
http://www.nabble.com/Slf4J---user-f13203.html

Which jar files have you placed on your class path?

For FileAppender the file attribute should be:

   <file>c:/testlog1.log</file>
