Business functions that are Invoke-able over the Internet/IntranetUsing transports such as HTTP and SMTP, and others

– Note: Locally optimized transports are interesting tooThat 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 XMLFew temporal constraints -- no long locks, allow think time and latencyHigh 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

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

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 enabledSOAP/HTTP-R -- reliable, but less ubiquitous, internet enabledSOAP/SMTP -- mail-oriented, high latency, store-forwardSOAP/JMS or XML/JMS -- asynchronous, high latency, leverages existing providersRMI/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

Discussion Topics

• What is the role of XML?– A data representation for information exchange or

more?– How does XML fit into the J2EE model?– How do you map persistence to XML stores?

• Synchrony vs. Asynchrony– Do the messaging models and application server

models converge?– What do we tell customers?
