Java Module in EAR results in DeploymentException

Question

I'm trying to deploy an ear containing ejb jar files, third-party jar files,
and war files and I get the following error:
<Oct 17, 2001 3:41:53 PM GMT-08:00> <Error> <Management> <Error initializing
module log4j.jar of application mydomain:Name=frontier-1,Type=Application
from path ./config/mydomain/applications/frontier.ear:
weblogic.management.DeploymentException: unknown module type:
weblogic.j2ee.dd.JavaModuleDescriptor>
The dtd for the application xml document as described here
http://e-docs.bea.com/wls/docs61/programming/app_xml.html#1010332 says that
a module may have a java element, however the exception message above seems
to indicate it it not supported?
Help please!

Answer 1

After opening a support case with BEA, I found out that the recommended way
to resolve class loader dependencies is to use the "Class-Path" attribute in
the archive's manifest file. Also the classloaders are supposed to resolve
dependencies uniquely and cumulatively. That is to say if I had 3 jar files
(A,B,C), two with log4j.jar as values for the Class-Path manifest attribute
and dependencies amongst all three as shown below, the resulting classpath
would be :
B.jar : log4j.jar : C.jar : A.jar
A's manifest:
Class-Path: B.jar log4j.jar
B's manifest:
Class-Path: C.jar
C's manifest:
Class-Path: A.jar log4j.jar
More info about the manifest and how extensions work is available here
(http://java.sun.com/docs/books/tutorial/jar/basics/manifest.html#download).
Hope this helps!
