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.  Jul. 16, 2008

j1-2k8-mtW05: Best practices and examples in writing integration logic with OpenESB

j1-2k8-mtT13: EDR-MDS A less is more aproach to Master Data Services
Service Oriented Architecture is all over us. There seems to be some kind of consensus that one type of SOa services are domain object repository services - and vendors are monitoring and releasing their SOA Data Server products to close the gap. By pioneering the SOA space with EDR, we quickly had to solve the Master Data challenge in SOA. This talk will discuss the main contenders for the ownership of your business objects definitions, and comment on their consequences - and then follow up with a "less is more" approach to enable companies to gain the combined advantages of all the platforms by extending the EDR pattern to also include Master Data Service features.  Jun. 18, 2008

j1-2k8-mtT12: EDR - Master Your Distributed Data
The Enterprise Domain Repository (EDR) pattern recognizes that we are still in the stone age of data integration. EDR is a new pattern gathering these challenges into a service that produces real Domain Objects, while also coping with the complexity of handling disjointed data-sources, back-end performance and mastering strategies. EDR is the result of experiences gained working with .Net and Java customers. Now we want to work with the Community to improve on the usage of this pattern.  Jun. 13, 2008

j1-2k8-mtT01: Enabling Semantic Web Technologies with JBI
Semantic web is a way to represent and manipulate informations that allows very high flexibility on the way the information are aggregated, accessed and presented. To leverage existing information base we need ways to get these information and translate them into a semantic form. There many standard ontologies broadly accepted like FOAF (for representing person data and person relationships), DOAP (for representing project data), Dublin Core (for representing document data) etc.... The act of transforming information from a proprietary format to a semantic representation is called rdf-alization. An ESB JBI can be the right integration middleware to perform this task because it can easily collect data in proprietary format from different sources and, by redefining rdf-alizers as JBI component, can feed semantic web enabled application.  May. 13, 2008

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. May. 31, 2007

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. May. 25, 2007
