How to use global services?

Hi, I have a DAO to access configurations, this DAO must be accessible by all pages but I don't want to declare an inject for it in each page especification.
I think I could place it in the Global class, but I don't know how neither where to "inject" this dao in the global class.
What is the best solution for this?
Thank you.

Re: How to use global services?

Is there a way to access the Hivemind service/bean provider, so that 
instead of using annotations, I can do something like this in my Page class:

public abstract class MyPage extends BasePage {
    /* define setters and getters for service1 and service2 ... */
    public MyPage() {
        init();
    }

    public void init() {
        setService1(SomeHivemindHook.getService("service1"));
        setService2(SomeHivemindHook.getService("service2"));
    }
}

Something like this?

Thanks,

MARK

Why you don't makin' a class for it, which includes this inject and then inherit all over Pages from this class and not from BasePage.
This should be the simplest Solution i think, but i'm a noob, too.


public abstract class upperclass extends BasePage
&#123;
@Inject&#40;"Property"&#41;
public abstract String getProperty&#40;&#41;;

..
&#125;

public class underclass extends upperclass
&#123;
&nbsp; public void ..&#40;&#41;
&nbsp; &#123;
&nbsp; &nbsp; String prop = getProperty&#40;&#41;;
&nbsp; &#125;
&#125;

I think it is the easiest way ... in fact all my page classes already extends a custom class. I just need to inject the dao in the class.

Another aproach that can be used is described in
