What About Interoperability?

J2EE .NetBEA

Oracle

Sun

IBM

Microsoft

XMLSOAPWSDLUDDILDAP,SMTP,

…

Others

Web Services Interoperability Issues Type Encoding

– explicit typing of parameters (eg., "xsd:integer" vs "xsd:int" )

SOAPAction Header – Some implementations support both SOAPAction values of "" and null,

while others do not

Message Parameters– Some toolkits have the ability to set multiple out params, while most

toolkits can process one and only one out param

– Order of parameters for return types on the client side.

SOAP Envelope– Encoding style, envelope level or body level?

– Namespace qualification

– IDs and Href

Web Services Interoperability

SOAPBuilders – Grassroots organization – Canonical set of tests, testing interoperability on live

implementations– soapbuilders@yahoo.com

WS-I.org– Industry initiative for Web services interoperability– Open to any organization committed to Web services– Promote and accelerate adoption, deployment of Web

services

WS-I Profiles

Names groups of Web services specifications for interoperability purposes

Defines how best to use combinations of specifications together

Enables industry to define interoperability levels
