The Eclipse plug-in for WebSphere Service Registry and Repository slipped out last Friday as SupportPac SA02. The plug-in requires an Eclipse Version 3.0.2 or later shell so will work fine with WebSphere Integration Developer and Rational Application Developer. It enables the Registry to be queried, artefacts extracted from the Repository and then these, or other artefacts, published back to the Repository. Properties can be modified on artefacts and relationships added between them. Importantly, unlike the web GUI, the plug-in enables collections of artefacts to be published together without having to worry about the order in which they need to be published.
*cough* it should also work with Message Brokers Toolkit. I’ll try it out asap and let you know.
