You can access the different scopes via the following implicit objects:
pageScope, requestScope, sessionScope, applicationScope.

Thanks Satou kurinosuke


I tried that and it works. But does that mean web designers are supposed to know the scope of attributes they are trying to access.

Better say that you usually put a variable in only one scope, to avoid troubles. Putting the same variable in different scope is asking for troubles
