Customization of OAErrorPage in OAF

Question

Hi,
When an unexpected error occurs in OAF, the OAErrorPage is rendered with the text “You have encountered an unexpected error. Please contact the System Administrator for assistance”.
We are looking for a solution to display a custom message for such unexpected errors.
One solution that we have is using the try/catch with generic exception, to catch all exceptions raised and then throw the custom message.
Please provide us with the details if we can somehow customize the OAErrorPage to display a custom message and if this customization (if possible) can be restricted to a particular module/responsibility.
Any other solution to handle unexpected errors and display of custom message is welcome.
Thanks in advance.

This Errors is coming from within OA Framework implementation code and developers dont have direct access. Generally these errors come for cases which are not normally handled in code: like the null pointer exception wihch can never occur if a not null check is done before every dot operation. Similarly there can be other cases of System exception. If the code is written with lot of exception handling most of these issues would not occur and you would be free to show custom error messages on screen.
It might need some investigation to identify the actual piece of code causing it and making changes. However it might be a very costly exercise in terms of efforts with little output. Do make your decision.
