[logback-user] DynamicClassLoadingException - How does class loading in logback works?

[Jenny]

Hi,
 
I'm sorry for the earlier posts, my keyboard enter key was malfunctioning.

I'm using weblogic 10, and deployed my application as EAR. My custom appender is located in the WEB-INF/lib. I am getting this ClassNotFoundException.
 

app.ear
    - web1.war 
         - WEB-INF/lib
                customAppenderPackage.jar
 
So I've tried the following but still it can't find it:
- deploying customAppenderPackage.jar as a shared library
- putting in APP-INF/lib/customAppenderPackage.jar
- adding in the MANIFEST Class-Path
- adding as "library-ref" in weblogic.xml and weblogic-application.xml
 
The only one that worked is when I moved the customAppenderPackage.jar in my weblogic server domain library directory. But I don't want this... I want it to be inside my EAR package.
 
Any ideas how to solve this?
