What are the two types of Validations supported by Validator Framework in Struts?
In the Struts framework, the Validator Framework supports two main types of validations:
Client-Side Validation: This type of validation is performed on the client side, typically using JavaScript. It allows for immediate feedback to the user without requiring a round trip to the server. Client-side validation can help improve user experience by catching errors before the form is submitted. However, it is important to note that client-side validation can be bypassed, so it should not be solely relied upon for security.
Server-Side Validation: This type of validation is performed on the server after the form is submitted. It ensures that the data received from the client is valid and meets the required criteria before processing it further. Server-side validation is crucial for security and data integrity, as it cannot be bypassed by the user.
Both types of validation can be used together to provide a robust validation mechanism in a Struts application.
