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..
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.
