Hi,

I am using an applet which downloads jar files to the client machine cache. in those jar files I have log4j-1.2.7.jar and commons-logging.jar... log4j will be used to show only "ERROR" on client console.. but when my applet loads first time in the browser, it makes call to server for below mentioned classes which are not available in log4j jar.. i dont understand from where this call is made and how can I remove it..

GET http://test.server.com/upload/commons-logging.properties 404 Not Found
GET http://test.server.com/upload/META-INF/services/org.apache.commons.logging.LogFactory 404 Not Found

Also this happens again when i close the browser and start again...

i think it may have something to do with the log4j.conf file which is like below...
:::::::::::::::
log4j.logger.com.asite = ERROR,stdout,R

log4j.appender.CONSOLE=org.apache.log4j.ConsoleAppender
log4j.appender.CONSOLE.layout=org.apache.log4j.PatternLayout
log4j.appender.CONSOLE.layout.ConversionPattern=%d [%t] %-5p - %m%n0
log4j.logger.AssemblyLine.myAL=ERROR, CONSOLE
log4j.logger.EventHandler.myEH=ERROR, CONSOLE
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.R=org.apache.log4j.ConsoleAppender
log4j.appender.R.layout=org.apache.log4j.PatternLayout
log4j.appender.R.layout.ConversionPattern=%5p [%t] (%C:%L) - %m%n
log4j.appender.R.Target=System.err
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.rootCategory=ERROR, stdout ,R
log4j.appender.stdout.Threshold=ERROR
log4j.appender.CONSOLE.Threshold=ERROR

log4j.logger.com.elink.jbe=ERROR,stdout,R

:::::::::::::::::::::

can anyone give some idea...

thanks..

You probably can't get rid of those messages, short of not using log4j. log4j can be configured in a number of ways, including through various files, so the class loader is looking for those files. So these are not actually signs of errors, and can be ignored.

Ohh.. so can I make some change in the configuration of log4j itself sothat i dont get these??? or is this default implementation of log4j??

No, it's the default to look for these.
