What is OAF? What is ADF?
What is "offline database" and what is its purpose?
What is your Oracle version?

OAF : Oracle Application Developer Framework
ADF: Application Development Framework

Oracle Version : 10g

Offline DataBase:
in centralize data base , other sites people need inter net connection to access data base but its not possible to get net connection each time.

I don't know, it depends on your requirements, most of the time you just get an error.

Well, I can give one example what I have done:

I have an application that does stuff in ERP/Inventory control that requires a database. It runs on mobile devices, and these devices are sometimes out of reach of the access points, when people work on construction sites etc...

And since stuff absolutely *needs* to be moved even in a disaster scenario where the database is gone entirely I have included the following fall-back functionality:

When there is no connection to the database the application is still able to record stock IDs and quantities, and store them in list where each list can be given an ID.

So the user for example can't generate a bill of delivery without a database connection, but the user is still able to record the article number and the quantity and "name" the list with a generic name (it then gets saved to a local file on the device). Once the database connection is established again, the user can generate the bill of delivery by loading that article list.

So the first thing you need to do is find out how often you don't have a database connection, and what stuff you still need to be able to do without a database connection. Then write your program in a way that makes it possible to do that.

Does any of the two work without a database? So far I have only worked with either "plain" Java or C++ for my applications.
