NPC's not staying on restart.

Hey guys. I'm building up a server, because I really just want to host one, and it's an awesome chance for me to get my Java skills more advanced, but I am having a trouble with my NPC's in the Free Market.
I'm trying to put them in the Free Market just as a quick go-to for members, but after I restart the server, the NPC's disappear completely.
If anyone can help me fix this problem, and make them stay permanently, that will be amazing.

Are you trying to use the !pnpc code or something like that to spawn them?

I'm using the !npc command.

Code:

---

if (sub[0].equals("npc")) {
            MapleNPC npc = MapleLifeFactory.getNPC(Integer.parseInt(sub[1]));
            if (npc != null) {
                npc.setPosition(player.getPosition());
                npc.setCy(player.getPosition().y);
                npc.setRx0(player.getPosition().x + 50);
                npc.setRx1(player.getPosition().x - 50);
                npc.setFh(player.getMap().getFootholds().findBelow(c.getPlayer().getPosition()).getId());
                player.getMap().addMapObject(npc);
                player.getMap().broadcastMessage(MaplePacketCreator.spawnNPC(npc));
            }

Is the code for the command.
