ClassNotFoundException, classloader issue, how to share a ja

We are trying to share a jar library between our EJB and WEB modules. Right now, we have placed our shared jar in the root of the EAR and added Class-Path tags to the MANIFEST.MF files of the EAR and WAR. At deploy time, it throws the following exception:

java.lang.ClassNotFoundException: org.apache.myfaces.component.html.ext.HtmlDataTablePhaseListener
at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1332)
at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1181)
at com.sun.faces.util.Util.loadClass(Util.java:406)
....

The directory structure is as follows
theEar.ear
shared.jar
WEB.WAR
META-INF
MANIFEST.MF (Class-Path: shared.jar)
EJB.JAR
META-INF
MANIFEST.MF (Class-Path: shared.jar)

Thank you for your help.

to clairify: the directory is like this:

theEar.ear
----shared.jar
----WEB.WAR
------META-INF
--------MANIFEST.MF (Class-Path: shared.jar)
----EJB.JAR
------META-INF
--------MANIFEST.MF (Class-Path: shared.jar)

Thank you for your help.

Instead of mentioning in the Manifest file, try out this:

Add an entry in application.xml file under your ear/META-INF directory as follows:
<module> <java>shared.jar</java> </module>

Tried that, and I didn't notice a difference in results. I tried placing the code in various places in the file too.....

I've had the exactly same result. This is a very tricky issue ... Is there anybody at jboss group that could help ? The deployment process at jboss AS is a nightmare...

Thanks.
