Course: Web Application Development with Struts

Register

This advanced course shows JSP and servlet programmers how to build web applications using the Apache Struts framework. Students learn the Struts architecture and see how it captures a great deal of pre-existing best practice: in model/view/controller action mappings, form beans and custom tags for working with HTML forms, input validation, and the Tiles view-building framework. Two chapters near the end of the course cover configuration techniques and other advanced topics. This version of the course illustrates the use of Struts 1.3; see the previous version for coverage of Struts 1.1.

Duration: 24 hours (12 Sessions)

Price: 11400 Baht (VAT included)

Class Schedule: Monday 20.00-22.00, Wednesday 20.00-22.00, and Saturday 13:00-15:00

Course Goals

• Use Struts actions and action mappings to take control of HTTP requests/responses.
• Manage HTML form input and output with form beans, and use these beans to simplify data handling in the controller.
• Use JSTL and Struts custom tags to build robust and reusable JSP presentation logic.
• Support multiple client locales with various internationalization techniques.
• Define validation rules for input forms, and provide clear user feedback.
• Build complex presentations using decoupled, reusable tiles, screens and layouts.

Course Prerequisites

Java programming, Servlets programming, and JSP.
