Not it doesn't, action is action, result is result, don't mix them in
@Action. See simple example:
public class RegisterAction extends ActionSupport {
@Action("register") // basically not needed, just to show what I mean
public String execute() {
if (something)
return "success";
else
return "input";
}
}
and under WEB-INF/content/
- register-success.jsp (or just register.jsp)
- register-input.jsp

Read documentation [1] how the Convention plugin is working, basically
