David Jencks reassigned GERONIMO-2693:
--------------------------------------
Assignee: David Jencks
> Application classloader contains a massive number of duplicate classpath
> entries
> --------------------------------------------------------------------------------
>
> Key: GERONIMO-2693
> URL: https://issues.apache.org/jira/browse/GERONIMO-2693
> Project: Geronimo
> Issue Type: Bug
> Security Level: public(Regular issues)
> Components: kernel
> Affects Versions: 1.1.1
> Environment: WAS CE 1.1.0.1
> Reporter: Mike Perham
> Assigned To: David Jencks
> Attachments: cpath.txt

>
> 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.
