ROUND 2 SOAP Interoperability Tests Specification: Group "B" Methods

This specification outlines a (proposed) SOAP service interface that can be implemented by SOAP implementations as part of an interoperability testing process. It introduces methods with more complex serialization requirements than those of the base "interop" interface.

General Guidelines

SOAP Version 1.1 will be used.
For this method set, implementations may carry explicit typing information on the wire, but should not require it for incoming messages.
Since we are dealing strictly with Section 5 encoding, encodingStyle should be present and set to http://schemas.xmlsoap.org/soap/encoding/
All server and client envelopes should conform to the WSDL document located at http://www.whitemesa.com/interop/InteropTestB.wsdl

The list of methods follows. Sample envelopes are provided as well. It is important to note that these envelope examples are ONLY examples, and there is no implication that the implementations need to conform to these specific envelopes.

echoStructAsSimpleTypes
echoSimpleTypesAsStruct
echo2DStringArray
echoNestedStruct
echoNestedArray

method: echoStructAsSimpleTypes

This method accepts a single struct and echoes it back to the client decomposed into three output parameters.

An example of this structure is:

<ExampleStruct>

<varString>Hello</varString>

<varInt>8</varInt>

<varFloat>10.2</varFloat>

</ExampleStruct>

The structure is defined with the following schema:

<complexType name="SOAPStruct">
    <complexContent>
	<all>
		<element name="varString" type="xsd:string"/>
		<element name="varInt" type="xsd:int"/> 
		<element name="varFloat" type="xsd:float"/> 
	</all>
    </complexContent>
</complexType>

This type is defined within the namespace http://soapinterop.org/xsd

Input parameter name : inputStruct

Input parameter type: sb:SOAPStruct where xmlns:sb="http://soapinterop.org/xsd"

Output parameter name: outputString

Output parameter type: xsd:string

Output parameter name: outputInteger

Output parameter type: xsd:int

Output parameter name: outputFloat

Output parameter type: xsd:float
