Podrobnosti:
Developing JavaServer Faces Components with Ajax provides you with the skills necessary to build custom web tier components for the JavaServer Faces (JSF) framework that leverage Ajax techniques. The JSF framework is an extensible set of user interface components with an application programming interface (API) for dynamically managing application state, event handling, input validation, page navigation, as well as support for internationalization and accessibility. Ajax is an emerging web application development technique that leverages client-side JavaScript to provide a richer and more responsive user experience than can be achieved by server-side logic alone. The focus of this course is to show how you can incorporate Ajax technology in reusable JSF components using design techniques that complement both technologies. Students that can benefit from this course: Java developers who create reusable web components (such as JSP custom tags) for the assembly and generation of dynamic web content.
