Web Services Overview
Author: Paul King
Last Revised: June 2006
Synopsis
This presentation describes the core and emerging web service technologies that are
currently being standardised within standards bodies, and being promoted or experimented
with by vendors and users.
Some of the technologies examined include:
| Core Technologies |
XML, SOAP, WSDL, UDDI (plus a quick comparison to REST) |
| Security |
The WS-Security family of specifications, WS-Trust and WS-Federation |
| .Net Language/Environment Support |
GXA and WSE |
| Java/J2EE Language/Environment Support |
JAXP, JAXR, JAX-RPC, SAAJ, JAXB and JAXM |
| Transactions |
BTP vs WS-CAF vs WS-Transactions |
| Notifications/Events |
WS-Eventing vs WS-Notifications (WS-BaseNotification, WS-BrokeredNotification, WS-Topics) |
| Reliable Messaging |
WS-Reliability vs WS-ReliableMessaging |
| Managing Resources |
REST vs WS-Transfer vs WS-ResourceFramework (WS-ResourceProperties, WS-ResourceLifetime, WS-RenewableReferences, WS-ServiceGroup, WS-BaseFaults) |
Other topics discussed include WS-Addressing, the WS-Policy family of specifications and others.
The talk also covers the technologies for collaboration/choreography such as BPEL and WS-CDL.
A key observation for nearly every main functional area is that competing "standards"
are currently being promoted and significant consolidation is still required before we will have
a clear picture of the important long-term WS technologies.
The slides also include a quick look at tools and supporting technologies (XML Parsers, XPath, XSLT, XQuery, XML Data Binding) for working with XML and Web Services.
