I'm working on 2 Hands On Labs for JavaOne this year:

• Building RIA Dojo and JavaFX™ Pet Catalog Clients for MySQL™ backed RESTful Web Services
• Developing Real-Time Revolutionary Web Applications, Using Comet and Ajax
  

You can read the HOL details and download some preview documentation and code below:

• Session ID:       LAB-6771
• Session Title:     Building RIA Dojo and JavaFX™ Pet Catalog Clients for MySQL™ backed RESTful Web Services
• Session Abstract:    
  
  • The goal of the Java™ API for RESTful Web Services (JAX-RS) is to provide a high-level declarative programming model for such services that is easy to use and encourages development according to REST tenets. Services built with this API are deployable with a variety of Web container technologies and benefit from built-in support for best-practice HTTP usage patterns and conventions.
    This Hands-on Lab provides an overview of the JAX-RS API and walks developers through the design process for a sample RESTful service.
    Dojo is an open-source DHTML toolkit written in the JavaScript™ programming language. The new JavaFX™ platform brings rich Internet applications to all the screens of your life.
    In the lab, participants will use the NetBeans™ IDE to rapidly develop JAX-RS, Dojo, and JavaFX applications and then deploy them on the GlassFish™ application server, with Java DB or the MySQL™ database.

• Session ID:       LAB-5558
• Session Title:     Developing Real-Time Revolutionary Web Applications, Using Comet and Ajax
• Session Abstract:    
  
  • Join the asynchronous Web revolution! Emerging Ajax techniques -- variously called Ajax Push, Comet, and HTTP streaming -- are bringing revolutionary changes to Web application interactivity, moving the Web into the Participation Age. Because Ajax-based applications are almost becoming the de facto technology for designing Web-based applications, it is more and more important that such applications react on the fly, or in real time, to both client and server events. Aajx can be used to enable the browser to request information from the Web server but does not allow a server to push updates to a browser. Comet solves this problem. It is a technology that enables Web clients and Web servers to communicate asynchronously, enabling real-time operations and functions previously unheard of with traditional Web applications to approach the capabilities of desktop applications.
