Wonderland is an interesting 3D collaboration application. It uses the darkstar server as backend. Project http://underworld.dev.java.net goal is porting the Wonderland's communication and persistence layer to Glassfish v2 (later v3) to leverage its non-functional capabilities like monitoring, management, deployment and scaleability. In this shorttalk, especially the architecture and design, as well as, challenges, hacks, and workarounds will be discussed.

The City and County of San Francisco (Department of the Environment) and Marin County are collaborating with the City of Oakland Public Works on an effort to assess and promote solar power opportunities in our communities. The City and County of San Francisco and Marin have been doing digital assessments. We are collaborating with the City of Oakland to transition from a paper-based approach to a web-based approach where much of the effort is delegated to the client/server.

ME Framework is an testing framework for the Java ME platform developed as part of the cqME open-source project. A set of plug-ins for the open-source JT Harness, ME Framework provides support for application and platform quality and conformance testing needs. This mini-talk covers testing framework features, Java ME application and security models, communication protocols optimization and debugging functionality.

This mini talk addresses how Glassfish and OpenESB helped solve the problem of connecting disparate, secured networks for the purposes of running an exercise. These networks only allow incoming XMPP traffic to enter their domain. Gestalt’s, now part of Accenture, XMPP Binding Component coordinated a secure VPN to run an exercise. This solution decreased the exercise setup time from months to minutes.

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

This session will show how to use a SunSPOT to control a TrackBot. Attendees will be shown how to take code created using the TrackBotsAndGreenfoot session and send it to a SunSPOT, although attendance at that session is not a prerequisite. Basics of how to compile and deploy for this device will be covered.

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.

BlueJ is the most used educational development environment worldwide. This presentation, by one of the lead developers of BlueJ, shows what BlueJ is, what it can do, and how it may be used in teaching and learning object-oriented programming. BlueJ is widely used at universities, colleges, schools and in OO training.

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.
June 18, 2008
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.
