Subject Re: [Logging] : Can commons.logging be used without log4j
Date Thu, 12 Aug 2010 15:01:47 GMT
Can you pl be more specific on classpath?

I found webapp-classpath-first check box during the deployment which now I 
have it checked. And that gets reflected on orion-web.xml as well. Also I 
added \WEB-INF\log4j.xml in my additional classpath. 

But still the logs are created in only 1 file for 2 web application on 
same instance.

Sounds like a classloader configuration issue.  OC4J probably has a
version of log4j on their classpath and it's bleeding over into the
classpath of your webapps.  Is there a webapp-classpath-first setting
