I want to write a Java program to use a BatchInserter to set up a database, which I will then access via the REST API from another application. The BatchInserter requires that I provide a directory for my database, but there doesn't appear to be any examples of how to use that directory in the REST API. What am I missing??

Thank you! I've been trying to read through the manual and the tutorials, and it seems like there are a lot of missing details that make it difficult to understand.

My neo4j-server.properties has: # location of the database directory org.neo4j.server.database.location=data/graph.db
My Java code using a BatchInserter to insert nodes is:
BatchInserter db = null; BufferedReader reader = null; DateFormat df = new SimpleDateFormat("yyyy/MM/dd"); Date today = new Date(); try { File graphDb = new File("data/graph.db"); if (graphDb.exists()) { FileUtils.deleteRecursively(graphDb);
}
long nodes = 0; Map<String, String> config = new HashMap<String, String>(); db = BatchInserters.inserter(dbpath); reader = new BufferedReader(new FileReader(new File(nodeFile))); System.out.println("Loading nodes.."); reader.readLine(); String line = null; while ((line = reader.readLine()) != null) { String[] lineData = line.split(","); Map<String, Object> prop = new HashMap<String, Object>(10); prop.put("Name", lineData[0]); prop.put("Type", lineData[1]); prop.put("DateCreated", today.getTime()); createNode(lineData[0], db, prop); nodes++;
}
System.out.println("Total nodes: "+nodes);
reader.close();
It executes successfully, but when I try to look at the database from the web interface, I don't see anything there. I also tried prepending 'server' to the directory, with no luck.

Probably you should use absolute paths in your batch inserter to make sure it ends up in the right place, otherwise it will be data/graph.db from the base of your java project (you might have to copy that).
Don't forget to stop your server before that and start if afterwards
