j1-2k7-mtT14: Keaton: Calling QTKit from Java
Want to play audio, video, or multimedia in a Java application? QuickTime for Java opened the door to Apple's extensive QuickTime library, but times are changing and QTJ seems headed for deprecation. In fact, Apple is pushing Mac developers away from the old procedural-C QuickTime API altogether. In its place is a new object-oriented, Cocoa-aligned framework called QTKit. Great for Objective-C programmers, but what about the Java crowd? The Keaton project, something of a successor to Lloyd, will create a one-to-one mapping of Java objects to Obj-C objects, so you can work with QTMovies and QTMovieViews directly in Java code. Come see this talk to see how it works and how you can use it in your Mac Java application.

j1-2k7-mtT12: Open Software Factory
The project Open Software Factory (aka openmodelerp) is an ongoing process to develop a set of tools and a corresponding set of methods for effective Model-Driven Software Development (MDSD).
Abstraction is fundamental to software development. Abstractions are provided by models. Modeling and model transformation constitute the core of MDSD. Models can be refined and finally be transformed into a technical implementation, i.e., a software system.
This talk will begin with a quick overview of basic MDSD concepts. The remainder of the talk will discuss how the Open Software Factory supports MDSD. We will summarize our current achievements and briefly outline our plans for the future. The talk will share our project's experience in both developing Open Software Factory and applying it to develop to simple 2 Demonstration applications. The following issues will be briefly mentioned in the talk.
- The apparent productivity gains of using OSF and the MDSD paradigm in general.
- The benefits of using OSF to make models more abstract, independent of their implementation.
- The efficient re-targeting of an application model to a new platform.
- The automation of repetitive parts of software development that are inherent when using current infrastructures (J2EE, Struts, Spring, Hibernate, JSF, etc ...).
- Combining the use of OSF with best practices of Agile Software Development and the resulting synergy.
- Implications for other development tools such as NetBeans to support MDSD.
- Current challenges for the Java Open Source community to have a complete toolchain to support MDSD, not tied to any specific vendor.

j1-2k7-mtT03: Web continuations with RIFE and Terracotta
State management has always been a complex and tricky part of web application development. Continuations simplify this and automatically allow you to create a one-to-one conversation between users and a web application. State preservation and flow control no longer need to be handled manually, bringing you back to the simplicity of single user console applications. Remember 'scanf()'?
This presentation will introduce continuations from general principles, followed by practical examples that explain how they benefit web application development and their frequent usage patterns. Finally, automatic fail-over and scalability will be demonstrated through the integration with Open Terracotta.

Validate Java EE Annotations with Annotation Processors
Annotations are one of Java 5's most compelling features, but their openness is in some ways a curse: there's nothing keeping you from declaring illegal combinations of annotations (like @Stateful and @Stateless). Annotation processors give you the opportunity to inspect annotations, either with the currently available Apt or or the upcoming JSR-269 annotation processor. Jason Li takes a look at both in this article.

From AWT to Swing, JSP to JSF, Ajax to JavaFX, a lot of time is spent developing GUIs to visually express relationships that are implicit, if not manifest, in the data itself. So why not let the data shape the GUI? Automatic GUI builders do just that, and in this article, Javier Paniza shows how OpenXava does it.

Binding Beans
Expressing GUI relationships through beans' getters and setters is a burdensome process of wiring that has frustrated many developers. Binding offers an alternative: automatically connecting a model value to its GUI representation. This style of programming is available to users of the JGoodies Binding framework, as well as the implementation of JSR-295, and in this article Thomas Künneth takes a look at both.

Create Moving Experiences with Animated Transitions
A GUI that radically changes its layout as it goes from one mode to the other can be jarring to users. A new trend is for changes in content or context to be animated, so the user can see the nature of the changes. In an example inspired by the the Filthy Rich Clients book he co-authored, Chet Haase introduces the Animated Transitions library, which can help you achieve these effects in your Swing application.

Interaction Happens: Prototyping Techniques
Do you prototype your GUIs? Should you? A great prototype can help work out the kinks in the flow of a GUI. But it can also get rushed into production as a seemingly (but not really) ready product, if you do too good a job of showing how your app will work. In this installment of "Interaction Happens," Jonathan Simon surveys the range of prototype options available to the GUI developer.

j1-2k8-mtW06: API compatibility puzzles
Many Java developers create API libraries for use by applications. Such libraries typically evolve over time, providing more and more functionality with each release. At the same time, it's important to preserve backward compatibility of the API so that the API libraries could be upgraded without any negative effects on existing applications.
This session focuses on a series of common API modifications that seem like normal modifications, but can manifest subtle compatibility problems. Attendees will acquire skills to evaluate API changes for backwards compatibility, and how to sidestep compatibility pitfalls.
The Java Conformance team at Sun has been part of the API evolution in both Java SE and ME, where preserving backward compatibility is critical to platform success. In this session we'd like to share our experience in this area. A short overview of compatibility problems in general will be presented, as well as the API compatibility puzzles.
