title: Neo4j configuration file
body: <p>I've tried to run a simple example "Hello World" with Neo4j but I don't know how to modify the configuration file.
  I don't know what to put as a parameter for </p>
  
  <pre><code>"GraphDatabaseService graphDB = new GraphDatabaseFactory()
                                             .newEmbeddedDatabase(" ..... ");"
  </code></pre>
  
  <p>and what other modification do I have to make. Do I have to put the org.neo4j.server.database.location from the neo4j-server.properties?</p>
  
  <p>But first, do I have to run the server?</p>
  
  <p>Thanks!</p>
