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

[Jenny]

I found a solution. I just put my customAppenderPackage.jar in the same level (same directory) where my logback.jar files are. thanks

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?
