> I have an EAR with an MDB jar and two WARs. The EAR contains a large number of jars within a lib directory. The wars and ejb-jar all contain MANIFEST.MF Class-Path entries which reference those jars within lib/.
> When I print out my WAR classpath, I get output attached. The duplications don't really matter all that much except for the duplications due to non-canonicalized paths:
> jar:file:/D:/perforce/depot/external/wasce/1.1.0.1/repository/com/ibm/websphere/fabric-tools-ear/6.0/fabric-tools-ear-6.0.car/lib/fabric-gov-api-1.4.0.jar!/META-INF
> jar:file:/D:/perforce/depot/external/wasce/1.1.0.1/repository/com/ibm/websphere/fabric-tools-ear/6.0/fabric-tools-ear-6.0.car/fabric-tools-web.war/../lib/fabric-gov-api-1.4.0.jar!/META-INF
> If I do a getResources("foo") and that gov-api jar has a foo resource, the system will think there are two foo resources when in fact there is only one, due to different URLs for the same resource. As a result, for instance, this causes Apache Hivemind to blow up with an error due to it thinking a component jar is doubly defined in the classpath.
> I'm unclear why Geronimo is adding all the lib jars to my classpath without my asking. It seems like the various J2EE modules should be able to control their own classpath wrt jars in the ear.
> This is a blocker preventing us from using our application on WAS CE.
