Hi Rupert,
I do not have dbpedia index available on ManagedSolrServer. Could you
please guide me how to achieve that? Do I need to install any bundle
to my OSGi environment?
Regards,
Manish
Note: If I include dependency like
org.apache.stanbol.commons.solr.managed in my module's pom file, then
it do not compile as it has in turn dependent on osgi.core.
