InterSystems: The power behind what matters   

Specifies the binding style or SOAP invocation mechanism used by this method, when it is used as a web method. Applies only in a class that is defined as a web service or web client.
To override the default binding style used by the method (when it is used as a web method), use the following syntax:
Method name(formal_spec) As returnclass [ WebMethod, SoapBindingStyle = soapbindingstyle ] 
Where soapbindingstyle is one of the following:
For a web service that you create manually, the default value of this keyword is usually suitable. When you generate a web client or service from a WSDL with the SOAP Wizard, Caché sets this keyword as appropriate for that WSDL; if you modify the value, your web client or service may no longer work.
This keyword lets you specify the binding style used by a web method. It affects the format of the SOAP body (but not any SOAP headers).
For a given method, this keyword overrides the SoapBindingStyle class keyword.
If you omit this keyword, the style attribute of <soap:operation> element is determined instead by the value for the SoapBindingStyle class keyword instead.
Relationship to WSDL
The SoapBindingStyle method keyword specifies the value of the style attribute of <soap:operation> element within the <binding> section of the WSDL. For example, if the SoapBindingStyle method keyword is document, the WSDL could look as follows:
<binding ...>
    <operation ...>
        <soap:operation ... style="document"/>
In contrast, if SoapBindingStyle is rpc, the WSDL could instead be as follows:
<binding ...>
    <operation ...>
        <soap:operation ... style="rpc"/>
The binding style also affects the request and response <message> elements for the web method, as follows:
Effect on SOAP Messages
For information, see the entry for the SoapBindingStyle class keyword.
Use with %XML.DataSet
If you use this keyword with a method that uses an object of type %XML.DataSet as input or output, some limitations apply. See the entry for the SoapBindingStyle class keyword.
