Data Type Mapping for Web Service Call-Out
A web service can contain any of the data types defined in the XML Schema Definition (XSD). This includes data types that Uniface does not support. The Uniface WSDL import facility maps each XML schema data type into a Uniface data type.
After importing a WSDL, you can modify the interface of the Uniface data type for each parameter, as long as it remains compatible with the Uniface data type. For example, change the length of a String parameter.
If you used the /gen switch when importing the WSDL, the parameter descriptions of complex parameters contains sample XML code that documents what is required for the parameter.
Note: Complex XML Schema data types should be treated as completely self-contained—if any element of a complex parameter requires a specific XML namespace, you need to ensure that each namespace is explicitly defined. For more information, see Complex Nested Parameters.
The following tables show the default mappings between Uniface and XML schema data types for Web service call-out.
