Google App Engine is a powerful cloud-computing platform designed to help developers more easily create and manage scalable web applications. With the recent addition of Java support, developers can now interact with the Google App Engine datastore using JDO and JPA, both standard Java persistence APIs. In this talk we will discuss how these standards allow you to create a "soft schema" on top of a schema-less datastore, and the advantages this soft schema provides. We will also explore how the datastore's "pre-sharded" transactional model is exposed in these standard interfaces. Finally, we will discuss how a soft schema maps to a traditional, relational schema, and examine some techniques for porting persistence code on and off App Engine.

The Java Card™ system is the smallest Java™ platform available, but what can you do with it? This session covers some interesting examples involving the playSIM development kit.

playSim is an open-source development kit for prototyping new and creative Java Card 3 technology-based applications without the hardware limitations of today's smart cards. It combines the flexibility of the open Sun SPOT platform with the hard security requirements of SIM-card-based applications. Sun SPOT is used as an execution engine as well as a modular hardware platform to enable connection of different types of sensors and I/O interfaces.

See how the presenters combine the flexibility of open-source technologies such as Sun SPOTs and Squawk Virtual Machine with the commercial license aspects of the Java Card 3 platform.

Come see how to

• Experiment with Java Card 3 in the embedded domain through the I/O capabilities of the Sun SPOT platform
• Get started with Java Card 3 Servlets, even without terminal support
• Simulate SIM and smart cards with embedded radios
• Experiment with Near Field Communication (NFC), using regular radios
• Create new machine-to-machine interactions
• Add one or two boards to a Sun SPOT and have a ready playSIM kit
• Simulate smart cards with gigabytes of memory, using ordinary MiniSD cards

Presented by Eric Arseneau, Sun Microsystems, and Fritjof Engelhardtsen, Telenor.

A great user experience incorporates three pillars: structure, behavior, and expression. In this preview, Chris Nesladek talks about the wide variety of interaction design patterns built into the Android system framework. He also demos an example of a well-designed Android app that illustrates how these three pillars can be used together.

For those who are attending I/O, we thought it might be useful to hear from some of the speakers in advance. These videos provide a preview of one or more topics that will be covered in their talks.

Summary

What is the Google Web Toolkit, what can you do with it, and why should you use it? Using our real world experience building Lombardi Blueprint as a case study this presentation will answer these questions.

We'll also touch on GWT's place in the development life cycle, including interaction with designers, the efficiency of the generated code, and present some useful design patterns and tips for making the best use of GWT.

Lombardi has been using GWT for nearly two years now. We've built a complete SaaS product, Lombardi Blueprint, and are using GWT extensively in our enterprise product, Teamworks, to provide both standalone Web UIs and in combination with Eclipse.

It's our belief that GWT should be your default choice for RIA development, this presentation will show you why.

Summary

Just as the Java language was extended in Java 5 to add generics, enumerations, and other features, a number of new language features are being developed for JDK7.

We examine the changes and their interactions, how they are conditioned by preexisting language design choices, and discuss how they influence the way APIs are designed.
