What About Interoperability? J2EE.Net BEA Oracle Sun IBM Microsoft XML SOAP WSDL UDDI LDAP, 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 –  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 Today Phase II “Security and Reliability” XML Digital Signature XML Encryption WS-Security HTTP-R SAML XACML … WS-I Basic Profile Phase 1 “Connection” XML Schema SOAP WSDL UDDI Phase III “Enterprise” Provisioning Transactions Workflow Systems management …
