AUDIENCE:   This course is intended for programmers who have been programming in Java servlets and JSPs, and who wish to write programsusing many of the advanced J2EE features. PREREQUISITES:   Students should have experience with Java programming, Servlets programming, JSP, and Basic knowledge of XML. DURATION:   3 days. Hands on. OBJECTIVES:   Apache Jakarta Struts shows JSP and servlet programmers how to build Web applications using the Jakarta Struts project from Apache. Delegates learn the Struts architecture and see how it captures a great deal of pre-existing best practice in Web application development. Delegates learn how to build applications from scratch using the Struts 1.2 code base, advancing through actions and action mappings, form beans, and request forwarding. They use relational data at the model layer and learn to configure JDBC data sources under Struts. Throughout, the course emphasises the great facility in Struts of using XML declarations to replace boilerplate Java coding. At the end of this course, delegates will be able to: - 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 persistent data in a Struts application with JDBC. - 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.
