9/82 Business functions that are Invoke-able over the Internet/Intranet Using transports such as HTTP and SMTP, and others – Note: Locally optimized transports are interesting too That typically use XML for information interchange Building blocks for more complex Web applications Success in the Internet requires loose coupling: Low technology barrier to entry -- HTTP and XML Few temporal constraints -- no long locks, allow think time and latency High version attenuation -- enable independent development cycles for interface changes Interoperability must be preserved Open Source provides reference implementations J2EE and other standards relavent to implementing business services Service Oriented Architectures: Web Services
10/82 Service-Oriented ArchitecturesService-Oriented Architectures WebSphere "Web Services" WebSphere extends existing applications to create Web Services without changing the programming model. Open standards based platform to build, test, deploy and publish Web Services. Web Services require standards for publish, find and bind. These are built on the base layers of our e-business infrastructure. Web Communications + (TCP/IP) Web User Interface + (HTML) Web Programming + (Javatm) Web Data + (XML) Web Services (SOAP, WSDL, UDDI…) = Next generation Service Registry Service Provider Service Requester
11/82 Leveraging Simple Beginnings Short Term: – Web services are a way of gaining access to business function over the internet through programmatic interfaces enabled by HTTP and SOAP Longer Term: – Web services are a way of describing business function that can be accessed over a variety of communication protocols – Focus is on WSDL Different binding protocols offer different qualities of service -- loose vs. tight coupling SOAP/HTTP -- un-reliable, but ubiquitous, internet enabled SOAP/HTTP-R -- reliable, but less ubiquitous, internet enabled SOAP/SMTP -- mail-oriented, high latency, store-forward SOAP/JMS or XML/JMS -- asynchronous, high latency, leverages existing providers RMI/IIOP -- synchronous, low latency, standardized service contexts – Choose the binding protocol that meets the needs of the business situation – Resolve the programming model issues of protocol transparency

16/82 Discussion TopicsDiscussion Topics • What is the role of XML? o A data representation for information exchange or more? o How does XML fit into the J2EE model? o How do you map persistence to XML stores? • Synchrony vs. Asynchrony o Do the messaging models and application server models converge? o What do we tell customers?
