In Java WS Core, resources are managed and discovered via ResourceHome implementations. The ResourceHome implementations can also be responsible for creating new resources, performing operations on a set of resources at a time, etc. ResourceHomes are configured in JNDI and are associated with a particular web service.

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) 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).
