%XML.DataSet creating invalid xml - intersystems-cache

Question

Class Services.TestClass Extends (%RegisteredObject, %XML.Adaptor)
{
Property DS As %XML.DataSet;
}
and the following web method inside my web service class:
Method HelloWorld(name As %String) As Services.TestClass [ WebMethod ]
{
Quit ##class(Services.TestClass).%New()
}
This produces the following XML:
<s:complexType name="TestClass">
<s:sequence>
<s:element minOccurs="0" name="DS" type="s0:DataSet"/>
</s:sequence>
</s:complexType>
<s:complexType name="s_DataSet">
<s:sequence>
<s:element ref="s:schema"/>
<s:any/>
</s:sequence>
</s:complexType>
</s:schema>
I believe s_DataSet name should actually be just DataSet, because s0:DataSet points to DataSet, not s_DataSet
When I use a client that consumes the service I get the following error: Error: type 'DataSet#http://tempuri.org' not found.
(from SoapUI)
When I take the DataSet property out of the TestClass and return it directly everything is fine. What is going on?

Answer 1

What you are showing us is (part of) the WSDL of the WebService (class).
s_Dataset is just a name, the schema part refers to the schema element.
Calling the webService :
... Serivices.Client.cls?soap_method=HelloWorld&name=zzz
Just produces:
<SOAP-ENV:Envelope>
<SOAP-ENV:Body>
<HelloWorldResponse>
<HelloWorldResult/>
</HelloWorldResponse>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>
No errors
