You seem to implying that the WARNING: multiple bundles are exporting package com.fasterxml.jackson... are the root cause - are you sure? It may well be - but you're not showing a clear exception stack trace proving it. > Bundle:tree-show 300 is captured here: http://pastebin.com/4MHq8FL9 > WARNING: multiple bundles are exporting package com.fasterxml.jackson.core - com.fasterxml.jackson.core.jackson-core_2.3.2 [275] - com.fasterxml.jackson.core.jackson-core_2.8.5 [290] > Here is or feature xml file definition > > > > <features name="example-${project.version}" xmlns="http://karaf.apache. > org/xmlns/features/v1.2.0" > > xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; > > xsi:schemaLocation="http://karaf.apache.org/xmlns/features/v1.2.0 > http://karaf.apache.org/xmlns/features/v1.2.0";> > > <repository>mvn:org.opendaylight.controller/features-mdsal/{{VERSION}}/ > xml/features</repository> > > <repository>mvn:org.opendaylight.netconf/features- > restconf/{{VERSION}}/xml/features</repository> > > <repository>mvn:org.opendaylight.netconf/features- > netconf-connector/{{VERSION}}/xml/features</repository> > > <feature name='example-api' version='${project.version}' > description='OpenDaylight :: baseservice :: api'> > > <feature version='${mdsal.model.version}'>odl-mdsal-models</feature> > > <feature version='${odl.mdsal.binding.base.version}'>odl-mdsal- > binding-base</feature> > > <bundle>mvn:com.adva.ensemble.controller/baseservice-api/{{ > VERSION}}</bundle> > > </feature> > > <feature name='jayway' version='${project.version}' description='Jayway > Library'> > > <bundle>mvn:com.fasterxml.jackson.core/jackson-databind/ > 2.6.3</bundle> > > <bundle>mvn:com.fasterxml.jackson.core/jackson-core/2.8.5</bundle> > > <bundle>mvn:com.fasterxml.jackson.core/jackson-annotations/2.8.0</bundle> > > > <bundle>wrap:mvn:org.apache.tapestry/tapestry-json/ > {{VERSION}}</bundle> > > <bundle>mvn:com.jayway.jsonpath/json-path/2.2.0</bundle> > > </feature> > > <feature name='example' version='${project.version}' > description='OpenDaylight :: baseservice'> > > <feature version='${feature.mdsal.version}'>odl-mdsal-broker</feature> > > <feature version='${project.version}'>example-api</feature> > > <feature version='${feature.netconf.connector.version}'>odl- > netconf-connector-all</feature> > > <feature version='${project.version}'>jayway</feature> > > <bundle>mvn:com.adva.ensemble.controller/baseservice-impl/{{ > VERSION}}</bundle> > > <bundle>mvn:com.sun.jersey/jersey-core/{{VERSION}}</bundle> > > <bundle>mvn:com.sun.jersey/jersey-client/{{VERSION}}</bundle> > > <bundle>mvn:com.google.code.gson/gson/{{VERSION}}</bundle> > > </feature> > > <feature name='example-rest' version='${project.version}' > description='OpenDaylight :: baseservice :: REST'> > > <feature version="${project.version}">example</feature> > > <feature version="${feature.restconf.version}">odl-restconf</feature> > > </feature> > > <feature name='example-ui' version='${project.version}' > description='OpenDaylight :: baseservice :: UI'> > > <feature version="${project.version}">example-rest</feature> > > <feature version="${feature.restconf.version}">odl-mdsal-apidocs</ > feature> > > <feature version="${feature.mdsal.version}">odl-mdsal-xsql</feature> > > <bundle>mvn:org.jolokia/jolokia-osgi/${org.jolokia. > osgi.version}</bundle> > > </feature> > > </features> > > > > > > Any suggestions on how to resolve the issue of “multiple bundles expose > the same package”? > My understanding of OSGi is that in theory it should be possible to load different version of library such as e.g. Jackson (that, together with the "dynamic" aspect of -again in theory- being able to load additional bundles at runtime/unload/reload, is sort of the main point of OSGi). In practice however, this only really works properly if all involved bundles MANIFEST.MF have appropriate version="[...,..)" ranges for all packages on BOTH their respective Export-Package: AND Import-Package: clauses... in practice, particular for "standard" Java libraries (e.g. Jackson), or for automatically wrapped ones (wrap:mvn:) that is often not the case, unfortunately. To resolve this, you would have to carefully review the MANIFEST.MF of all involved bundles, and likely fix version/s in some of them... if you really want to go through that effort - best of luck! One alternative you have, if you only need to use such 3rd party libraries from within ONE (!) of your bundles (say your com.adva.ensemble.controller/baseservice-impl thing), would be to "embed" 3rd party Java library JARs into your bundle, in say a lib/ in the bundle JAR (and add them to the classpath in the MANIFEST; the maven-bundle-plugin can do all this for you). FYI This is typically considered a "not so great" practice - because you prevent other bundles from accessing those shared libraries (and if two of your bundles need to access anything "static" in such an external library then it's definitely No Go to do this), but it also help to avoid the sort of problem you have, because you then keep that such libraries "private". Hope this helps.
