Here are some key points about Struts:

1. MVC Architecture: Struts encourages the separation of concerns in your web application. It divides the application into three main components: Model (business logic), View (presentation layer), and Controller (handling user input and requests).

2. Tag Libraries: Struts provides its own set of custom tag libraries that simplify the creation of dynamic web pages, making it easier to work with HTML forms and display data.

3. Validation Framework: Struts includes a built-in validation framework that allows you to define validation rules for form fields easily. This helps in ensuring that user inputs are valid and meet specific criteria.

4. Internationalization (i18n) Support: Struts provides support for internationalization, making it easier to create multilingual applications.

5. Integration: Struts can be integrated with various technologies and libraries, such as Hibernate for database access or Spring for dependency injection.

6. Configuration: Struts applications are typically configured through XML files, which define the mapping between URLs, actions, and views. This configuration approach provides flexibility and allows for easy changes without modifying code.

7. Ajax Support: While Struts 1.x primarily predates the rise of Ajax, Struts 2.x introduced improved support for Ajax functionality, making it possible to create more dynamic web applications.

8. Community and Resources: Struts has a large and active community, and there are plenty of tutorials, documentation, and online resources available to help developers get started and solve common problems.
