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

Demonstration 1 ASP.NET

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 What is a Web Service?

XML Web Services Explained Internet connects entities together 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 Connects People WWW Connects People to Information Web Services Connects Applications

The Future: WSA Use the SOAP header! WS-Security WS-Routing WS-Transaction WS-ReliableMessaging WS-I

Web Services Interoperability Organization (WS-I) Operational RequirementWS-I Deliverable Common definition for Web services Profiles Implementation scenarios Implementation guidance and support for Web services adoption Supporting documentation and whitepapers Sample code and applications Consistent, reliable interoperability between Web services technologies from multiple vendors Conformance testing tools Goal: Promote Web services interoperability across platforms, applications, and programming languages

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 UDDI 1.0 WSDL 1.1 SOAP 1.1 XML Schema 1.0
