New bee weblogic classloader

Question

I read some articles on weblogic classloading. This is what is my understanding any jar files needed by both ejb and war shoud be placed in the root of an ear file ,suppose i need log4j for both ejb and war i place it inside ear and add amanifest entry in ejb , and war can also see log4j becaue the war parent class-loader is ejb classloader.Now suppose I need struts jar for my war , Should I just place in web-inf/lib and no entry in war manifest ? is this right?
I am facing lot of troubles with my war classloader,any utility class I call in war I get get class not found exception, what stops war classloader not to see classes inside jar inside web-inf/lib ?

Isn't the documentation link I responded with pretty clear? APP-INF is a directory directly in the root of the EAR and you can create it yourself.
Class Loading for Shared Classes+
The classes and libraries stored under APP-INF/classes and APP-INF/lib are available to all modules in the Enterprise Application. The application classloader always attempts to resolve class requests by first looking in APP-INF/classes, then APP-INF/lib.
If you want to isolate jars and classes to a particular Web module, then you can put them in the Web module's WEB-INF/lib or use the manifest mechanism that you referenced. I find the manifest mechanism to be brittle in comparison, but it is standard and portable. Putting jars that I want in APP-INF/lib for universal access and WEB-INF/lib for web module isolated access is easier in my opinion because the location of the jar file denotes your intention.
