Create graphdb connection

Test.java

// Create the sail graph database
graphDb = new EmbeddedGraphDatabase("var/flights");
indexService = new LuceneIndexService(graphDb);
fulltextIndex = new SimpleFulltextIndex(graphDb, new File("var/flights/lucene-fulltext"));
rdfStore = new VerboseQuadStore(graphDb, indexService, null, fulltextIndex);
sail = new GraphDatabaseSail(graphDb, rdfStore);

// Initialize the sail store
sail.initialize();

// Get the sail repository connection
connection = new SailRepository(sail).getConnection();
