ATI's Jakarta Struts course


Share |

Summary:

    Technical Training Short On Site Course Quote

      This advanced course shows JSP and servlet programmers how to build "Model-2" Web applications using the Jakarta Struts project from Apache. Students learn the Struts architecture and see how it captures a great deal of pre-existing best practice in Web application development. They build applications from scratch using the Struts 1.1 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 emphasizes the great facility in Struts of using XML declarations to replace boilerplate Java coding.

      The course then shifts from these controller techniques to a focus on presentation. Students learn to use various libraries of custom JSP tags: the JSP Standard Tag Library (which supersedes a number of Struts tags), Struts HTML tags for form-building and validation, and the Tiles library for robust and reusable page layouts.

      Two chapters near the end of the course treat issues of effective Struts development: one focuses on "under the hood" coding techniques and one on best practices at a design level. By the end of the course, students are building complex, internationalized Web applications that validate user input, handle error conditions gracefully, and make best use and reuse of control and presentation logic through actions, form beans, validators, business and persistence JavaBeans, and Tiles.

    Prerequisites:

      Students should have experience with Java programming, Servlets programming, JSP, and Basic knowledge of XML.

    Who Should Attend:

      This course is intended for programmers who have been programming in Java and who wish to write programs in Java using many of the advanced Java features.

    Benefits of Attendance:

      The student will learn how 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.
