Your code modifying the database needs to run within the transaction:

public static void main(String args[]) {
        graphDb = new GraphDatabaseFactory().newEmbeddedDatabase(path);
        registerShutdownHook(graphDb);
        Transaction tx = graphDb.beginTx();
        try {


        firstNode = graphDb.createNode();
        firstNode.setProperty("message", "Hello, ");
        secondNode = graphDb.createNode();
        secondNode.setProperty("message", "World!");
        relationship = firstNode.createRelationshipTo(secondNode, RelTypes.KNOWS);
        relationship.setProperty("message", "brave Neo4j ");

            tx.success();
        } finally {
            tx.finish();
        }
    }

Also you should create the embedded database using the provided factory. See tutorial for version 2.1.7 http://neo4j.com/docs/2.1.7/tutorials-java-embedded-hello-world.html
