How to store global values for the whole application to use ?

Question

Hi,
In our application, we have global values that is store in a parameter table, I want only to query it once, and it will be used every where from the whole application.
e.g :
I have general parameter tables that store :
% Tax
Current Period
etc..
Then these values will be used in our business rules in the whole application.
How can I do that in ADF BC ?
Thank you,

I would go ahead and create a transient VO with an attribute called "userLanguage" and store the value at the initialization step.
We generally call this type of VO as PVO which is a transient VO and contains only 1 record at any point of time. Keep this VO inside the RootAM and you can write a static util method as below..
public static String getUserLanguageFromPVO()
PVOImpl pvo = (PVOImpl)am.findViewObject("MyPVO");
if(pvo != null)
Row row = pvo.first(); //Always returns the one record
return (row == null ? null :
(String)row.getAttribute("UserLanguage"));
return null;
}
