Rupert,
I have dbpedia index but does not know how to make use (install and
configured) of ManagedSolrServer in our osgi environment.
I googled but didn't find much on it except the link that you
forwarded me in your earlier mail but it had a high level view.
I am unable to find how exactly should I install and configure it in my OSGi.
Regards,
Manish
