The Java BluePrints talk for JavaOne 2006 is online and free. The talk, "Java BluePrints for Ajax-Enabled Web 2.0 Applications", discusses design choices for building a web application on the Java EE 5 platform. This talk covers some of the design choices and decisions made for the new Java Petstore 2.0, including

• When to use Ajax
• Page is the application style of architecture
• Applying the Model View Controller pattern
• Leveraging existing Ajax Libraries
• Designing a JSF Ajax-enabled component library
• Mashup architecture choices
• Design choices in the domain model
• And a lot more

You get a slide show that moves along with the recorded audio for the JavaOne talk we gave this year. The slide show has a written transcript of the presentations also. You can pause, fast forward, rewind. You can also can download a pdf of the slides, but slides alone do not give you as much information. You do need to create an SDN(Sun developer Network) login (also free).

Also, the other talks from 2005 and 2006 are available online also. Many developers go to JavaOne, but a lot more don't get to go, so this is a good way to see some of the talks. There are some other online Ajax talks from JavaOne 2006 also. For example,

• Introduction to AJAX : TS-4489 by Dion Almaer and Ben Galbraith.
• Using the Dojo Toolkit to Develop AJAX-Enabled Java EE Web Applications : TS-3577 by Alex Russell and Gregory Murray
• Evolving JavaServer Faces Technology: AJAX Done Right : TS-1161 by Adam Winer, Ed Burns, and Jacob Hookom.
• Smackdown for AJAX Programming Models and Frameworks : TS-2991 with representatives from DOJO, Flex, Swing, and JSF.
• Java Technology Techniques for Developing AJAX Applications : TS-3376 by some Google engineers Joel Webber and Bruce Johnson. It discusses GWT, the Google Web Toolkit
• JavaServer Faces, AJAX and Portlets: Developing Apps Without Distress : TS-6877 by Brendan Murray
• AJAX & Persistence: Emerging Patterns & Pain Points : TS-8614 by Larry White and Craig Russell

The best way to experience the Java BluePrints talk for JavaOne 2006 is online and free-- you dont even have to watch us sweat on stage.
