At least two enterprise service bus (ESB) vendors have recently announced enhancements to their products. Sonic Software has launched version 7.0 of its ESB, and Iona is about to release version 4.0 of its Artix, and version 1.0 of its open source offering, Celtix. The open source aspects of technology are common themes here.
Sonic's latest release has a number of new features - a new Workbench (based on the open source Eclipse framework, but with a number of Sonic-specific plug-ins as well), an integrated test environment, and advanced web services capability taking advantage of some of the latest WS-* 'standards' that are either with OASIS or still at the early (pre-standard) stage.
