Overview of OpenESB Sceencast

I've created a new screencast which provides an overview presentation of OpenESB, including how JBI works, and how OpenESB relates to JavaCAPS.

Having run OpenESB workshops with companies for almost 18 months now, I realise that it is easy to misunderstand the how a JBI-compliant infrastructure operates and also what information is needed by developers to design and build solutions.

JBI is a standard for infrastructure developers and the inner-workings really are not always relevant for developers building applications with a JBI compliant infrastructure. However, app developers should have an understanding of the basic concepts to understand what is happening. Many developers also like to know what is happening "under the covers" so that they fully understand how issues like performance, security, and transactions are handled by the infrastructure. Hopefully this presentation provides that information.

The presentation walks through an example, actually the tutorial problem which was detailed in the last entry, and explains how service interaction occurs and the role of the normalised message router from the developer's perspective.
