CommandDriven is an interface in WW 1.x and is implemented in ActionSupport. Basically, if you set a parameter into the Action named command, either through the configuration, as a form or URL parameter, or by creating a URL like http://localhost/action!commandName, then the implementation in ActionSupport, if you extend it, will call a method called doCommandName() and return its return value.
The idea for Xwork is to make this a core part of the framework, so it's not implemented only in ActionSupport, and to make it done by the ActionInvocation, rather than inside the execute() base method. In this way, you don't have to save a "command" property in your Action (although we could still do this too), but just have it call the other method instead of execute.
