Hi,
your problem is that xerces comes from different classloader.
Your bundle should not export these package: just import or private.
As the resolver uses xerces, they should go in the same classloader (so
from lib/endorsed).
Let me double check your use case.

Hello,
I've built a simple bundle which instanciate a

Testing the bundle "locally" (within the IDE) is working fine.
Deploying it into the /deploy folder is also fine (its status is "Active").
When running it (through Camel route), I get this stacktrace :

Ok, the class "CatalogManager" from package "org.apache.xml.resolver"
existed in compile-time but not in run-time. So I deploy
"org.apache.servicemix.bundles.xmlresolver" dependency into /deploy folder.
When executing in Karaf console the command "bundle:headers
<xmlresolver_bundle_id>", I get :
Export-Package =
...
org.apache.xml.resolver;uses:="org.apache.xml.resolver.helpers,javax.xml.parsers,org.apache.xml.resolver.readers";version=1.2,
...
Nevertheless, same stacktrace appears.
Even if I add the package "org.apache.xml.resolver" in the <Import-Package>
I get the same error...
Any idea of what's going on ?
I'm using ServiceMix 6.1.0 (w/ Karaf 3.0.5), running on Java 7.
Thanks,
Jean-Baptiste Martin
