Just fire a request to /solr/update?optimize=true from anywhere/anything that has access to the Solr server, e.g:

curl 'http://localhost:8983/solr/update?optimize=true'

Using solrj, you call the optimize method of the class CommonsHttpSolrServer.

See this question about how to know when the optimize is done.

    } catch (SolrServerException e) {
