Hello there, First of all I'm quite new to NON-SQL databases but this tutorial is probably good explained. And I've added some debugging messages Code: import java.util.ArrayList; import org.bukkit.Bukkit; import org.json.simple.JSONArray; import org.json.simple.JSONObject; import org.json.simple.parser.JSONParser; import org.json.simple.parser.ParseException; import com.mongodb.BasicDBObject; import com.mongodb.DB; import com.mongodb.DBCollection; import com.mongodb.DBCursor; import com.mongodb.MongoClient; import com.mongodb.util.JSON;
