I need to set a variable in the app_controller of CakePHP and then use it in my default layout file.
Is there a way to set this variable?

I think what he meant was, that he doesn't know where to set a variable since he's not in a specific function inside a controller. To have a variable (or anything else really) available everywhere, you have to put it in your AppController like this:
function beforeFilter()
{
$this->set('whatever', $whatever);
}
More on those callback functions here.

The callback functions in AppController are the place to $this->set() variables that you want available to all of your views and layouts. beforeFilter() is called before all controller actions. If you want to set a view variable after an action has run, use beforeRender(). You can access your other view variables in the $this->viewVars associative array.
function beforeRender() {
$new = "Universal " . $this->viewVars['layoutTitle'];
$this->set('universalTitle', $new);
}

You can use this to set the variable : $this->set(compact('currentJobId'));
It will set array at the same time it will set values to it.
