Answer / Manish Prasad

In Struts, you can customize validation rules by creating your own Validator classes and adding them to the Validation.xml file. Here's how:

1. Create a new Validator class that extends ActionValidator and implements the required methods (validate(), getValidationErrors()).
2. Define the validation rules for your custom Validator in the Validation.xml file, including the name of your Validator class and any necessary properties.
3. Configure your action classes to use your custom Validator by adding a validate() method that initializes and uses an instance of your Validator class.
4. Test your custom validation by submitting forms with invalid data and verifying that the correct error messages are displayed.
