What exactly are you trying to do? Are you trying to log info for a particular app? I am not an expert with Weblogic but I know log4j comes with Weblogic7.

I know on the project I am currently working on we include the log4j.jar into the WAR file when we build the app. That would be the way I would recommend but you could just add log4j into your classpath.

For instance, in the file setWLSEnv.cmd you can set the classpath. This is found in the bea/weblogic700/server/bin folder. The path should resemble the following:


CLASSPATH=%JAVA_HOME%lib ools.jar;%WL_HOME%serverlibweblogic_sp.jar;%WL_HOME%serverlibweblogic.jar;%CLASSPATH%

Add in your log4j.jar here

If anyone else has done anything with this let me know.

Hope this helps
