PaxExam --- 'javax.xml.stream' exposed via two dependency
chains
Hi,
I would like to test a bundle in PaxExam with
org.apache.felix.framework, but cannot get it to run because of the
error below
Unable to resolve resource core [core [31](R 31.0)] because it is
exposed to package 'javax.xml.stream'
from resources org.apache.felix.framework [org.apache.felix.framework
[0](R 0)] and
org.apache.servicemix.specs.stax-api-1.0
[org.apache.servicemix.specs.stax-api-1.0 [24](R 24.0)] via two
dependency chains.
Is there a solution for this problem? I did find any.
Thank you
Hubert

Hi Balázs
<<Hope this helps!
I hope so :-), I spent too long trying this to get to work, including setting some system packages, wich obviously was not enough.
Thank you ! Will let you know the result.
kind regards
Hubert

Hi Hubert,
I normally do not use javax.xml packages from the JDK. I created a bundle
that
- contains all xml-apis (all basic xml API)
- contains implementation for all API
- overrides some classes to use always the classloader of the bundle to
find implementations (when factory classes are used)
The bundle is available on maven-central:
http://search.maven.org/#artifactdetails%7Corg.everit.osgi.bundles%7Corg.everit.osgi.bundles.org.apache.xmlcommons.full%7C1.4.1-20150918%7Cbundle
If you use the bundle I mentioned, you should not install stax-api or any
other bundle that contains standard xml related API. Please note that the
bundle is intended for runtime use, not for compile time.
I use only that many packages from the JDK as it is really necessary (e.g.:
I use javax.sql.* packages from a bundle, too). I do that by specifying
system packages. With pax-exam, it is possible to define system-packages,
too. See:
http://stackoverflow.com/questions/18445194/how-to-specify-system-package-exports-in-pax-exam
If you use maven and want to know the list of packages that are not
available in any of your dependency (expecting that your dependencies are
OSGi bundles), you can use the following command:
mvn org.everit.osgi.dev:eosgi-maven-plugin:analyse
This goal checks your dependencies and writes out what could be missing
(including all JDK based packages). By having a look on the list, it is
much easier to define the system-packages.
Hope this helps!
Kind regards,
*Balázs **Zsoldos*
