I am using OC4J 10.1.3.5 App server on Windows. I have deployed 2 web applications on the same instance of OC4J where I have defined the shared library. Both applications use Struts, Spring, iBatis, apache commons libraries which I have defined as a shared library. Part of the apache loggins library I had to add log4j jar as well. So indirectly log4j-12.16.jar is declared as a shared-lib as well.
I have log4j.properties for both application pointing to different log file. But still when both applications are deployed and running, the logs are getting populated on only one file. During the deployment, I did check on webapp-classpath-first="true" setting to explicitly have log4j.properties of each individual application being load first. But nothing makes difference.
