Antonello,

Pass it in as a key/value pair in the constructor that takes a
configuration map:

   Map<String,String> params = new HashMap<String,String>();
   params.put( "use_memory_mapped_buffers", "false" );

   NeoService neo = new EmbeddedNeo( "neo-db", params );

Hope that helps.

Regards,
-Johan
