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

purposes
 Defines how best to use
combinations of
specifications together
