PrinciplePerformed workFurther development / Suggestions

Web Service

W3C definitionpublic interfaces and bindings are defined and described using XMLinteract with the Web service in a manner prescribed by its definition, using XML based messages conveyed by Internet protocols

Basic components of Web Service ArchitectureCommunicationService DescriptionDirectory Service

Web Service - Principle

SOAP

WSDL

optional, not used

The new parts added to the WSDL file are:new fault typeheader & fault messagesIntegration of fault into operation’sWS-Transfer “soapAction” for operation’sautomatic binding of the headers into the SOAP messageswsdl:service element with the Endpoint References

Web Service – Performed work

XSLT

New discover message just for MO’sUse of relationships for operationsAdaptation of notification mechanismMeta constraints for invocation of operations

Many other possibilities as advertisement of new endpointsoperational status of resourcecustomized requests and more

..need to be analyzed carefully!

Web Service – Further development

Web services interoperability

Web services interoperability 2 WS►I Tools

Interoperability testing tools 1.1

Tests

Test definition

Use WS-I tools for testing interoperability

Send a SetLabel and Receive a GetLabel

Verify the usage of WS-Management

Test of the xFer module (WS-transfer)

Generate java classes from WSDL file

Convert WSDL 1.1 to 2.0 with WSO2 tools
