Hi Sergey, today I read your mails again with a fresh mind, trying to make it work ;-) First, regarding the mail below, I saw that according to [1] the property "org.apache.cxf.rs.provider" is of Boolean type while you suggest to use it as a list of classnames. If I use it as a list of classnames whatsoever I get a java.lang.ClassNotFoundException: org.apache.cxf.jaxrs.provider.JSONProvider, the same for org.apache.cxf.rs.JAXBElementProvider. The same happens when I try to instantiate JSONProvider and register it as a service with the OSGI service registry via a DS Component with the following XML:
<scr:component enabled="true" immediate="true"
name="VzServiceRestJSONProviderComponent"
xmlns:scr="http://www.osgi.org/xmlns/scr/v1.0.0";>
<implementation class="org.apache.cxf.jaxrs.provider.JSONProvider"/>
<property name="service.pid" value="VzServiceRestJSONProvider"/>
<service servicefactory="false">
<provide interface="javax.ws.rs.ext.MessageBodyReader"/>
<provide interface="javax.ws.rs.ext.MessageBodyWriter"/>
</service>
</scr:component>
These are the bundles I installed (Pax Runner start script):
#!/bin/bash
pax-runner-1.4.0/bin/pax-run.sh\
--bootDelegation=sun.*,com.sun.*,javax.xml.bind,javax.xml.bind.*\
mvn:org.osgi/org.osgi.core/4....@1@nostart\
mvn:org.osgi/org.osgi.compendium/4....@1@nostart\
mvn:org.ops4j.pax.logging/pax-logging-...@2@nostart\
mvn:org.apache.cxf.dosgi/cxf-dosgi-ri-singlebundle-distribution/1...@2\
mvn:org.apache.felix/org.apache.felix.scr/1....@2\
mvn:org.codehaus.jettison/jettison/1...@2\
... (some more bundles of my app)
Inspecting the cxf-dosgi-ri-singlebundle-distribution bundle and browsing the
jar I can see that the class is included and the package is exported, therefore
I can't explain to myself why this doesn't work :-(
Do you have any clue why the Providers can't be found?
Regards,
Daniel
