This is the log4j.properties file used to create the logs you see on our interop site # Set root category priority to INFO and its only appender to CONSOLE. #log4j.rootCategory=INFO, CONSOLE log4j.rootCategory=INFO, CONSOLE,WWW #wire debugging of HTTP client #log4j.logger.httpclient.wire=DEBUG log4j.logger.org.smartfrog=INFO log4j.logger.org.smartfrog.sfcore.languages.cdl=DEBUG log4j.logger.org.smartfrog.services.cddlm=DEBUG log4j.logger.org.smartfrog.services.xml=DEBUG log4j.logger.org.smartfrog.services.deployapi=DEBUG log4j.logger.org.smartfrog.sfcore.languages.cdl.CdlCatalog=INFO log4j.logger.org.smartfrog.services.deployapi.binding.NuxStaxBuilder=INFO log4j.logger.org.smartfrog.projects.alpine=DEBUG # CONSOLE is set to be a ConsoleAppender using a PatternLayout. log4j.appender.CONSOLE=org.apache.log4j.ConsoleAppender log4j.appender.CONSOLE.Threshold=DEBUG log4j.appender.CONSOLE.layout=org.apache.log4j.PatternLayout #log4j.appender.CONSOLE.layout.ConversionPattern=- %m%n log4j.appender.CONSOLE.layout.ConversionPattern=%-4r %-5p %c %x - %m%n log4j.appender.WWW=org.apache.log4j.DailyRollingFileAppender log4j.appender.WWW.DatePattern='.'yyyy-MM-dd-HH'.html' log4j.appender.WWW.File=/home/slo/public_html/logs/server-log.html log4j.appender.WWW.layout=org.apache.log4j.HTMLLayout log4j.appender.WWW.layout.LocationInfo=true #the following options are for the RollingFileAppender, not the daily one #log4j.appender.WWW.MaxFileSize=1000KB #log4j.appender.WWW.MaxBackupIndex=48 The secret is the DailyRollingfileAppender with its HTMLLayout; this creates HTML pages and moves them every day -you need to create the destination directory as log4j fails if it is not already there. -to serve up the logs you need to publish them to a visible directory. We do this by deploying another jetty web app to serve the log direcotry -printing out the received messages is something that different stacks do differently. For Alpine I just wrote a LogMessageHandler that does nothing but log the current message. enjoy, -steve
