Problem with loading worlds.

Hi!

I'm making a simple plugin, just to learn something new about java. It will be multi-world teleport. To telepot someone from world to world I must first load both worlds. And here is a problem. I tried several metods:

First one:

Code:

    public void onEnable() {
        PluginManager pm = getServer().getPluginManager();
        pdfFile = this.getDescription();

        WorldCreator.name("FireWorld").createWorld();
        }

But this gives me error:

Code:

13:47:28 [SEVERE] Error occurred while enabling Plugin v1.0 (Is it up to date?): org/bukkit/WorldCreator

Secound one:

Code:

    public void onEnable() {
        PluginManager pm = getServer().getPluginManager();
        pdfFile = this.getDescription();

        this.getServer().createWorld(this.getServer().getWorld("FireWorld"), World.Environment.NORMAL);
    }

But this time world isn't even loaded.

I search for some tips, but I found only this:

I have last bukkit, from: 10.10.11r.

Can someone help me to solve this problem? This world is created I just want to load it.

 

Try reinstalling your CraftBukkit jar.

 

Haha, it works! It was so simple. Thanks ~!

 

The build you used for your server wasn't up to date with the one for your plugin. Thats why you got this error:

Code:

java.lang.ClassNotFoundException: org.bukkit.WorldCreator

 

also you might want to put load: startup in your plugin.yml so your world is created before all the other plugins are loads sinec oyur creating a world
