Struts 2 Date Validation

Custom validation in Struts 2 is achieved by extending the ActionSupport class and overriding the validate method. This method is automatically invoked before the execution of the action’s business logic. We’ll demonstrate this with a scenario where we validate a user’s birth date to ensure it is not only required but also follows a specific format.

Struts 2, a powerful web application framework for Java, offers robust support for form validation. Custom validation allows developers to enforce specific rules on user inputs, ensuring data integrity and providing meaningful error messages. In this guide, we’ll delve into the world of custom validation in Struts 2 by creating a practical example.
