Loading and saving world to disk

I'm creating a plugin that has 2 identical pre-generated worlds that are located in the server folder. People are periodically teleported to their exact coordinates on the other world.

I've looked at and experimented with the WorldCreator class, but I can't figure out how to load a world from disk and keep auto-saving to that world as people play.

Any help on this would be much appreciated!

I've tried to load a world using

Code:java

World world2;
WorldCreator otherworld = new WorldCreator("otherworld").environment(Environment.NORMAL).generateStructures(true).seed(0);
world2 = Bukkit.createWorld(otherworld);

There is a folder in the server directory called "otherworld" but I don't know if that is enough to make it work.

Really? Has nobody ever used this class before? Do I have a unique problem nobody has ever come across before?

So let me get something straight -
You want to generate an identical world to the second every time the server is started? Or do you want every change in world 1 to be shown in world 2 (ie they are literally the same world)? Or..?

 

wait isn't it the overworld not otherworld?
