[equinox-dev] Double loading of resource?

[Peter Neubauer <peter@xxxxxxxxxxx>]

Hi,
I'm having a strange problem getting tapestry to run in the Jetty-PDE-RSP-UI scenario.

The tapestry libs are located in a special lib bundle, only .jar files, and a manifest that looks like

Manifest-Version: 1.0
Bundle-ManifestVersion: 2
Bundle-Name: Tapestry Plug-in
Bundle-SymbolicName: org.apache.tapestry;singleton:=true
Bundle-Version: 4.0.0
Bundle-ClassPath: commons-codec-1.3.jar,
 commons-fileupload-1.0.jar,
 commons-logging-1.0.4.jar,
 hivemind-1.1.1.jar,
 hivemind-lib-1.1.1.jar,
 javassist-3.0.jar,
 log4j-1.2.8.jar,
 ognl-2.6.7.jar,
 oro-2.0.8.jar,
 tapestry-4.0.1.jar,
 tapestry-annotations-4.0.1.jar,
 tapestry-contrib-4.0.1.jar,
 tapestry-portlet-4.0.1.jar
Bundle-Localization: plugin
Export-Package: javassist,
 javassist.bytecode,..........

Now, when the tapestry classloader scans the classpath, apparently there is a double resource discovered from 2 different URLs, the hivemodule.xml from the hivemind.jar:
......
DEBUG - Processing modules visible to org.apache.hivemind.impl.DefaultClassResolver@9e4585
DEBUG - Parsing bundleresource://1/META-INF/hivemodule.xml
DEBUG - Result: ModuleDescriptor[moduleId=hivemind version=1.1.0]
.
.
.

DEBUG - Parsing bundleresource://1:6/META-INF/hivemodule.xml
DEBUG - Result: ModuleDescriptor[moduleId=hivemind version=1.1.0]

resulting in

org.apache.hivemind.ApplicationRuntimeException: Error: Module hivemind is duplicated!  Definition in bundleresource://1:6/META-INF/hivemodule.xml has been ignored in favor of existing definition from bundleresource://1/META-INF/hivemodule.xml.

org.eclipse.equinox.servlet.ext.HttpServiceCustomizer.addingService(HttpServiceCustomizer.java:43)


The bundle 1 is the tapestry bundle. And there is no hivemodule.xml in the METAINF dir of the module, just in the JARs.
Anyone seeing what is happening?

Thanks
