Server Controls
• Programmable, server-side objects
•
•
 Properties, methods and events
Encapsulate both behavior and rendering
 HTML, XML, WML, script, etc.
You can create server controls
 Custom controls
 User controls
 Or derive from existing controls

What is a Web Service?
•
•
•
A component that provides a service to a
consumer
 Components potentially have global reach
 Consumers use a standard Internet protocol
(HTTP) and data format (XML)
Web services can be implemented in many
languages
 The consumer does not care which
The basis of B2X applications
XML Web Services Explained
•
•
•
Internet connects entities
together
Email and WWW
inherently cross
boundaries
XML Web Services
applies the same
platform neutral
approach to system
integration
 Platform Neutral
 Leverage Existing
Standards
 No Rip and Replace

Web Services Interoperability
Organization (WS-I)
Goal: Promote Web services interoperability across platforms,
applications, and programming languages
Operational Requirement
WS-I Deliverable
• Common definition for Web
• Profiles
• Implementation scenarios
• Supporting documentation
services
• Implementation guidance
and support for Web services and whitepapers
adoption
• Sample code and
applications
• Consistent, reliable
interoperability between Web
services technologies from
multiple vendors
• Conformance testing tools
WS-I Profiles
• Profile: Group of Web services
specifications at specific version levels
• Profiles make it easier to discuss Web
services interoperability
• First profile: WS-I Basic
