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. 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.

11. 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

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?
