AJAX / Oracle Articles by Andrei Cioroianu

Using EJB3 with AJAX
Learn how to build a Java EE application that uses AJAX, JavaServer Faces, and ADF Faces for the Web tier and EJB3 for the business logic. You'll see how to create entities, session beans, AJAX controller servlets, JSP pages that generate AJAX responses, and JSF forms based on ADF Faces. In the last part of the article, you'll find reusable JavaScript functions for creating, initializing and deleting XMLHttpRequest objects. You'll also learn several AJAX techniques, such as using callback wrappers, submitting the form data with AJAX, and preventing memory leaks in the Web browser.

Developing Smart Web UIs with AJAX, JSF and ADF Faces
This article shows how to use AJAX with the existing components of the JSF and ADF Faces frameworks and how to create Web applications based on AJAX, JSF, and ADF Faces with the help of Oracle JDeveloper. You'll learn how to build a simple AJAX controller and JSP pages that generate the response XML for the AJAX requests. After that, you'll find a full overview of the XMLHttpRequest API with code samples and usage patterns. Next, the article focuses on building the Web user interface with JDeveloper and you'll find more details about the JavaScript code that runs on the client side.

Enabling Data Exchange in AJAX Applications
Learn how to transfer data between AJAX clients and Java servers with XML and JavaScript Object Notation (JSON). The goal of this article is to provide everything you need for implementing data exchange in AJAX applications, using the best techniques and the most recent APIs.

Working with Ajax Table Editors and Viewers
This article shows how to build a Web-based table editor that allows the user to insert/delete rows and undo changes without waiting for a server response and without losing the scroll position. The table component will also act as a viewer that uses Ajax to retrieve information from a data feed. You’ll learn how to use JavaScript to build a table model, create the table editor/viewer, validate data with regular expressions, access the data feed, use event handlers, and monitor the data changes in the Web browser. In addition, the article presents a very interesting technique for generating XML and HTML on the client side, using a JSP-like syntax that makes the code more readable and easier to maintain.
