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";
           return "input";

and under WEB-INF/content/
- register-success.jsp (or just register.jsp)
- register-input.jsp

ognl.OgnlException: target is null for setProperty(null, "age", [Ljava.lang.String;@340556b3)"
> I also attached a "message" property to the HelloAction but it didn´t appear in the
page, so the execute() method wasn´t called!
> I´m afraid the Action classes are not being found.

(the name of the project) but it still doesn´t work... :S

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