PL/SQL web service - how to use XML schema to define inputs/outputs?

Question

Hello,
let us say I want to publish a PL/SQL web service. The package spec that I want to expose is:
CREATE OR REPLACE PACKAGE myWebService AS
  FUNCTION loadResults(
    username   IN VARCHAR2,
    password   IN VARCHAR2,
    resultData IN XMLType)
  RETURN XMLType;
END;When I use JDeveloper's wizard to publish my PL/SQL web service, the resulting WSDL contains this:
<schema
    xmlns="http://www.w3.org/2001/XMLSchema"
    xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:soap11-enc="http://schemas.xmlsoap.org/soap/encoding/"
    xmlns:tns="http://uk/co/weatherbys/aapws/AAPWS.wsdl/types/"
    targetNamespace="http://uk/co/weatherbys/aapws/AAPWS.wsdl/types/"
    elementFormDefault="qualified">
    <element name="loadresultsElement">
        <complexType>
            <sequence>
                <element name="username" type="string" nillable="true"/>
                <element name="password" type="string" nillable="true"/>
                <element name="resultdata" nillable="true">
                    <complexType>
                       <sequence>
                            <any/>
                         </sequence>
                    </complexType>
                </element>
            </sequence>
        </complexType>
    </element>
    <element name="loadresultsResponseElement">
        <complexType>
            <sequence>
                <element name="result" nillable="true">
                   <complexType>
                        <sequence>
                            <any/>
                        </sequence>
                    </complexType>
                </element>
            </sequence>
        </complexType>
    </element>
</schema>It is specifying that anything at all can be passed in and out from the two XMLType arguments, which is fair enough: it has no way of knowing what I am expecting and what I shall return.
My question is, how do I tell JDeveloper that actually I want either or both of those XMLTypes to conform to a particular XML schema?

Answer 1

You cannot format the date as a string, unless you do the conversion on the PL-SQL side, before you use it in your WebService mapping. It should be handled as a string.
The only way to convert the XML from SOAP, using this encoding, into literal XML is to apply XSLT to the payload. Not sure why you would like to do this, as the payload should be consumed by another SOAP-awared stack.
Hope this helps,
