Hi,

Having to do a data validation on new inputs from ADF Screen with multiple concurrent sessions. VO validation will not work as it uses a cache version.

Can i know how to do validation against Database?

Do i implement the validation in the Application Module or Entity object?

JDEV 12.2.1.1.0

Regards,

Varun

    HI ,

    View Object validation will be implemented to the client, but not to the EO nor the database,

    Entity Object validation will be implemented to both View Object and Entity object and not to the Database,

    Database Validation will be implemented to All Vo, EO and The Database,

    So The Database validation is your best Choice, and will be implemented to all when you are building the EO and VO and will be evaluated during the Commit operation.

    regards

    Hammam

    Hello Varun,

    If you like input validation on the client side then,

    In the Structure window, right-click the component for which you would like to add a validator.

    In the context menu, choose Insert inside <UI component>, then ADF Faces to insert an ADF Faces validator, or JSF Core to insert a JSF reference implementation validator.

    Choose a validator tag (for example, ValidateDateTimeRange).

    Thanks,

    Hart

    I want to do a validation on back end side.

    Does it have to be in the view object implementation or entity object implementation?

    we are always using database validation, nothing else.

    You should always have DB valdiation anyway, so why boring framework with additional job?
