WebSphere Application Server has introduced a new strategy for releasing additional functionality on top of existing versions, to be known as feature packs. There is now a beta of the WebSphere Application Server Version 6.1 Feature Pack for Web Services available. This feature pack will eventually deliver support for a raft of new Web service standards (WS-Reliable Messaging, WS-Addressing, MTOM and WS-Secure Conversations) along with updating the supported levels of existing standards (JAX-WS 2.0, JAXB 2.0, SAAJ 1.3 and StAX 1.0). The new Web services standards introduced form the basis of the RAMP Profile (Reliable Asynchronous Messaging Profile).
