Log4j configuration in class libraries

Hi there, what's the recommended strategy for someone releasing a class library which assumes a certain Log4j configuration? I'm assuming reading the configuration file should be done only once and in the main program, not in a class library. Background is that in the Log4perl world, people are

Newbie Question

I am using Log4j for the first time. How do I set up a property file (correctly) so I only log to a file and not to the console? I only want messages at level INFO or higher in my log file. This is what I tried. It didn't work: log4j.rootLogger = INFO log4j.DamlBuilder=INFO, FILE

Steven, Thanks. This works, but I still get output to the screen (standard out?) as well. Is there a way to prevent this? Neil -Original Message- From: Ebersole, Steven [mailto:[EMAIL PROTECTED] Sent: Friday, July 11, 2003 12:07 PM To: 'Log4J Users List' Subject: RE: Newbie Question

How are you doing the initialization of log4j? Are you possibly using jakarta-commons-logging or using something that uses it? -Original Message- From: Hainer, Neil [mailto:[EMAIL PROTECTED] Sent: Friday, July 11, 2003 11:21 AM To: Log4J Users List Subject: RE: Newbie Question

RE: Newbie Question

I initialize it with the following line of code: private static Logger logger = Logger.getLogger( DamlBuilder.class ); The only other line is: logger.info( Input file: + getInputFileName() + two_spaces + Output file: + getOutputFileName() + two_spaces +

RE: Newbie Question

You say just part of a java app... Some other part of that app must be doing something with log4j. Try the code in your last message in a simple main method using the property file; something like: public class Tester { private static Logger logger = Logger.getLogger( Tester.class );

RE: Newbie Question

Sorry, bad copy and paste job. The property file should actually look like: log4j.rootLogger=INFO log4j.logger.DamlBuilder=INFO,FILE log4j.additivity.DamlBuilder=false log4j.appender.FILE=org.apache.log4j.FileAppender log4j.appender.FILE.File=./log.txt
