Hi Friends


can anyone explain the difference between using ActionForm validate() method and validation.xml,when these two methods are in demand.



Thank you

Hi,

validation.xml comes with struts validator framework. It gives you certain set of validation rules, which you can use conveniently from xml files. But with ActionForm validate method you need to write your validation rules programmatically. So I think validator framework makes it more convenient for you.

validation.xml will take care of the validation for common fields that can appear in a form and also based on the data types that is involved.

Normally since we are going for DynaActionForms these days, we do not need any implementation of the validate method.
