Is it possible to turn a Minecraft single player map into multi-player server? [closed]

I've got some funky minecraft maps that I'd like to share with my friends. However, they're, more often than not, far away and unable to stop by my computer and see what I've wrought.

I was wondering if there was a way to transform a singleplayer map into a multiplayer one, such that I could share my singleplayer creations remotely?

Solution 1:

Yes, just copy the world you want to share to minecraft server directory, delete old world named "world", and rename the directory of your single player world to "world". You can insert single player world into SMP.

Solution 2:

Alright, here we go. Go to "run" and type "%appdata%". After that, click on the ".minecraft" folder. Look in there for a folder named "saves". Open that up and leave that there. Next, go to "Minecraft.net", press download, and then click on and download "Minecraft Server.exe", which should be 270 kilobytes big. Alternatively, you could use "Minecraft Server.jar", which is smaller. Once you are done with that, copy the world that you want to convert (from the "saves" folder) and paste it in the server folder. Now delete the folder called "world", and then rename your map folder's name to "world". Then go to "Mincraft_Server". It will take some time to load, but will get there.

Solution 3:

You can always just e-mail them the map if you want them to see and play on it, but that will of course only allows them to play it in single player. If you want to be able to play it with them, you'll need to set up a server, like Riki137's answer states.
