Základní info
Develop, and implement an end to end web 2.0 application using proven model-view-controller (MVC) and form processing patterns. The student programs a Web 2.0 front-end using JavaScript, Ajax, the Dojo Toolkit, CSS, and HTML to provide a rich user experience. On the server side, Java MVC patterns are used to write application logic and controls. On the back-end, the developers write and modify code that utilizes the Java Persistance API (JPA) and the modern version of Enterprise JavaBean (EJB 3.0) to maintain the data in the database. This is an end to end Web 2.0 application on top of a corporate quality database.Students who can benefit from this course: Developers who are creating web sites using JavaScript technology, or other web presentation technologies, and web components (such as servlets and custom tags).
