Mikkel Damsgaard has spent the last 5 years designing and programming thread intensive pseudo realtime systems for the logistic industry. The last year he has been employed at conscius a/s located in Aalborg, Denmark, where he is Chief of Development and the architect behind the framework CoWorks which is the topic of the talk.

Presentation: "CoWorks - A message based framework"

Wednesday 11:00 - 11:45 Private Room

Making solutions for the industrial world puts some rather exotic demands on the architecture of the application. The application reacts to certain realworld events, ie photocells blocked, actuators set, motor speed change etc, and needs to have some way of synchronizing these event. The speaker thinks that the best way to synchronize these events is to use message queues and some sort of a task metaphore. In java conscius has designed a framework that has abstractions similar to message queues and tasks, and have a very simple call semantic where messages are just normal message invocations. Futhermore the framework contains support for both asynchronous and synchronous method invocations.
To do this the DynamicProxy class of j2sdk 1.3 is used extensively to convert message invocations to messages. The talk will focus mainly on the design issues involved and explain exactly how the DynamicProxy is used to accomplish this.
