GT 4.2.0: Java WS Core


The Java WS Core is an implementation of the Web Services Resource Framework (WSRF) and the Web Service Notification (WSN) family of standards. It provides APIs and tools for building stateful Web services. The Java WS Core provides a Java-based container (web services hosting environment) and is the default container in a default GT installation. Commands can be used with any WSRF-based service/resource. The following GT 4.2.0 components are based on the Java WS Core [fixme verify]:

Web Services Notification (WSN)

The WS-Notification family of specifications define a pattern-based approach to allowing Web services to disseminate information to one another. This framework comprises mechanisms for basic notification (WS-Notification), topic-based notification (WS-Topics), and brokered notification (WS-BrokeredNotification). See the OASIS Web Services Notification (WSN) TC for details.

Web Services Resource Framework (WSRF)

Web Services Resource Framework (WSRF) is a specification that extends web services for grid applications by giving them the ability to retain state information while at the same time retaining statelessness (using resources). The combination of a web service and a resource is referred to as a WS-Resource. WSRF is a collection of different specifications that manage WS-Resources.

This framework comprises mechanisms to describe views on the state (WS-ResourceProperties), to support management of the state through properties associated with the Web service (WS-ResourceLifetime), to describe how these mechanisms are extensible to groups of Web services (WS-ServiceGroup), and to deal with faults (WS-BaseFaults).
