10.  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

11. Service-Oriented Architectures
Service Registry
Service Provider Service Requester

12. 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

17. 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?
