j1-2k8-mtW06: API compatibility puzzles   16 Jul 2008 04:00 GMT
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.

j1-2k8-mtW05: Best practices and examples in writing integration logic with OpenESB   11 Jul 2008 04:00 GMT
SOA is about decoupling application that need to be integrated through the use of services. To achieve a good degree of decoupling two main ingredients are needed: a good middleware and a well written integration logic. This session will show examples and best practices on writing integration logic inside a JBI ESB. Some topics that the session will touch are: -- synchronous vs asynchronous integration -- stateless vs stateful integration For each pattern the session will show a way to implement it using a JBI ESB, discussing advantages and common pitfalls

j1-2k8-mtW03: Comet and Bayeux   04 Jul 2008 04:00 GMT
Ajax has become quite popular as websites have become richer and richer. Ajax allows a page to periodically request data from the server. Comet, on the other hand, allows the server to push data to the client at any time. Comet applications are starting to redefine the capabilities of Web 2.0 applicaions. Bayeux, which is still in daft, is the first standard to define a comet based transport protocol. This talk will discuss the basics of Comet and Bayeux.
