log4j.configuration takes a URL, not a file path? Douglas E Wegscheid Lead Technical Analyst, Whirlpool Corporation (269)-923-5278

I have corrected the configuration accordingly so that loggers are defined for the two main packages: log4j.rootCategory=DEBUG log4j.category.hibernate.objects=DEBUG,A2 log4j.category.iceObjects=DEBUG,A2 ..... However the file log4j.properties doesn't get picked by the classloader. I've tried also setting the property -Dlog4j.configuration=/u02/oracle/user_projects/log4j.properties and adding the folder in the CLASSPATH variable but still Weblogic cannot pickup the file at startup: log4j: Trying to find [/u02/oracle/user_projects/log4j.properties] using sun.misc.launcher$appclassloa...@d9f9c3 class loader. log4j: Trying to find [/u02/oracle/user_projects/log4j.properties] using ClassLoader.getSystemResource(). log4j: Could not find resource: [/u02/oracle/user_projects/log4j.properties]. Is there anything else I can try to let WLS pickup the file ? thanks a lot Federico Douglas E Wegscheid wrote: > > log4j.category.hibernate.objects and log4j.category.iceObjects are set > twice, the second setting has no appenders specified.
