Hello, welcome to the forum.
I'm not exactly sure here, but I suppose the cTeam class represents a team within the minecraft's scoreboard system. That means you first need to initialize the scoreboard somehow, add a team to it and then you can work with it. I have a feeling that this is not exactly what you wanted, is it? Perhaps give us an overview of what you want to accomplish, then we could help you more.
(I have edited your post to use the shcode tag for the plugin code)
