Thanks Mark...I will use it with 4.1. For now, I used httpclient to call the Collections api directly (do a Get on http://127.0.0.1:8983/solr/admin/collections?action=CREATE etc). This is working.

In 4.1 you can use the CloudSolrServer with the collections API. - Mark On Jan 6, 2013, at 8:42 PM, Jay Parashar <jparas...@itscape.com> wrote: > The exception "No live SolrServers" is being thrown when trying to > create a new Collection ( code at end of this mail).
