Web service calls

Question

I have created a web service which I would liked to be called from an xfa form.  The service has two basic operations, getDataService and getStuffService which return an int and string respectively.  I am able to create a DataConnection from the wsdl file associated with this web service, and from the DataConnection I can drag relevant fields and buttons onto a form.  <br /><br />However, only the getDataService operation works.  When I click the button to execute the getStuffService nothing happens.  On looking at the SOAP message (given below) sent by the form, it appears that the operation is not getting included in the service request.<br /><br /><?xml version="1.0" encoding="UTF-8"?><br /><soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"><br />  <soap:Body/><br /></soap:Envelope><br /><br />I have used other programs to call both operations without problems so I am assuning that the wsdl file is OK, but here it is just in case:<br /><br /><?xml version="1.0" encoding="UTF-8"?><br /><wsdl:definitions targetNamespace="http://myservice.org" xmlns:apachesoap="http://xml.apache.org/xml-soap" xmlns:impl="http://myservice.org" xmlns:intf="http://myservice.org" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns:wsdlsoap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:xsd="http://www.w3.org/2001/XMLSchema"><br /><!--WSDL created by Apache Axis version: 1.2beta3<br />Built on Aug 01, 2004 (05:59:22 PDT)--><br /> <wsdl:types><br />  <schema elementFormDefault="qualified" targetNamespace="http://myservice.org" xmlns="http://www.w3.org/2001/XMLSchema"><br />   <complexType name="Data"><br />    <sequence><br />     <element name="data" type="xsd:int"/><br />    </sequence><br />   </complexType><br />   <element name="getDataServiceReturn" type="impl:Data"/><br />   <complexType name="Stuff"><br />    <sequence><br />     <element name="stuff" nillable="true" type="xsd:string"/><br />    </sequence><br />   </complexType><br />   <element name="getStuffServiceReturn" type="impl:Stuff"/><br />  </schema><br /> </wsdl:types><br />   <wsdl:message name="getDataServiceResponse"><br />      <wsdl:part element="impl:getDataServiceReturn" name="getDataServiceReturn"/><br />   </wsdl:message><br />   <wsdl:message name="getDataServiceRequest"><br />   </wsdl:message><br />   <wsdl:message name="getStuffServiceResponse"><br />      <wsdl:part element="impl:getStuffServiceReturn" name="getStuffServiceReturn"/><br />   </wsdl:message><br />   <wsdl:message name="getStuffServiceRequest"><br />   </wsdl:message><br />   <wsdl:portType name="MyService"><br />      <wsdl:operation name="getDataService"><br />         <wsdl:input message="impl:getDataServiceRequest" name="getDataServiceRequest"/><br />         <wsdl:output message="impl:getDataServiceResponse" name="getDataServiceResponse"/><br />      </wsdl:operation><br />      <wsdl:operation name="getStuffService"><br />         <wsdl:input message="impl:getStuffServiceRequest" name="getStuffServiceRequest"/><br />         <wsdl:output message="impl:getStuffServiceResponse" name="getStuffServiceResponse"/><br />      </wsdl:operation><br />   </wsdl:portType><br />   <wsdl:binding name="MyServiceSoapBinding" type="impl:MyService"><br />      <wsdlsoap:binding style="document" transport="http://schemas.xmlsoap.org/soap/http"/><br />      <wsdl:operation name="getDataService"><br />         <wsdlsoap:operation soapAction=""/><br />         <wsdl:input name="getDataServiceRequest"><br />            <wsdlsoap:body use="literal"/><br />         </wsdl:input><br />         <wsdl:output name="getDataServiceResponse"><br />            <wsdlsoap:body use="literal"/><br />         </wsdl:output><br />      </wsdl:operation><br />      <wsdl:operation name="getStuffService"><br />         <wsdlsoap:operation soapAction=""/><br />         <wsdl:input name="getStuffServiceRequest"><br />            <wsdlsoap:body use="literal"/><br />         </wsdl:input><br />         <wsdl:output name="getStuffServiceResponse"><br />            <wsdlsoap:body use="literal"/><br />         </wsdl:output><br />      </wsdl:op

Answer 1

In reply to Jimmy, yes I believe the action button is only associated with one service operation.
As an update, I have been told that some web services rely solely on the parameters of a call to determine which operation to invoke (hence no operation in the SOAP request). As I have two methods with the same set of parameters (i.e. no parameters) then it isn't surprising that only one operation works. Therefore I have modified my operations to take different parameters.
The problem now is that even though the getStuffService operation is being called (as verified by inspecting SOAP request and response messages at the server), the response is not appearing in the appropriate field on the form. Any ideas?
