I downloaded the most recent recommended build of craft bukkit, put it in my server folder and it starts up perfectly fine. But i try and connect to it and it says outdated server. I have no plugins and it is a fresh server. Thanks in advance! Anyone able to help me? EDIT by Moderator: merged posts, please use the edit button instead of double posting.
The latest recommended build is not for latest Minecraft. Try the beta build: http://dl.bukkit.org/latest-beta/craftbukkit-beta.jar
