Hi Arunan, Solr runs in one of two main modes: "Cloud" mode or "Standalone" mode. Collections can only be created in Cloud mode. Standalone mode doesn't allow creation of collections; it uses cores instead. From your error message above, it looks like the problem is that you're trying to create a collection in "standalone" mode, which doesn't support that.
SolrJ has methods to create both cores and collections, you just have to have Solr running in the right mode: - Collection creation: https://lucene.apache.org/solr/7_4_0/solr-solrj/org/apache/solr/client/solrj/request/CollectionAdminRequest.Create.html - Core creation: https://lucene.apache.org/solr/7_4_0/solr-solrj/org/apache/solr/client/solrj/request/CoreAdminRequest.Create.html You'll have to decide whether you want to run Solr in cloud or standalone mode, and adjust your core/collection creation accordingly.
