Question Web Services Proxy Class is Returning an Empty Response Instance

[RLBrehm]

Hi,
I am working on my first Web Services client project. I have a relatively simple web service running on an Apache/Tomcat server. I have used the Web Services Explorer of Eclipse to test and verify the behavior of the web service. I have used the “Add Web Reference” option of Visual Studio to generate the proxy class and add it to the project. The request message is pasted below:
<System.Web.Services.Protocols.SoapDocumentMethodAttribute("urn:LOOKUP_DATE_DESC", _
Use:=System.Web.Services.Description.SoapBindingUse.Literal, _
ParameterStyle:=System.Web.Services.Protocols.SoapParameterStyle.Bare)> _
Public Function LOOKUP_DATE_DESC(<System.Xml.Serialization.XmlElementAttribute( _ [Namespace]:="http://appdev.cincom.com/MantisServer")> _
ByVal REQ_DATE_DESC As REQ_DATE_DESC) As _ System.Xml.Serialization.XmlElementAttribute("RESP_DATE_DESC_OUT", _
[Namespace]:="http://appdev.cincom.com/MantisServer")> RESP_DATE_DESC_OUT
Dim results() As Object = Me.Invoke("LOOKUP_DATE_DESC", New Object() {REQ_DATE_DESC})
Return CType(results(0),RESP_DATE_DESC_OUT)
End Function

The classes for request objects are defined as:

<System.Xml.Serialization.XmlTypeAttribute([Namespace]:="http://appdev.cincom.com/MantisServer")> _
Public Class REQ_DATE_DESC
Public CONTROL As CONTROL
Public REQ_DATE_DESC_FORM As REQ_DATE_DESC_FORM
End Class

<System.Xml.Serialization.XmlTypeAttribute([Namespace]:="http://appdev.cincom.com/MantisServer")> _
Public Class CONTROL
Public NAME As String
Public CLEARANCE As String
Public PARAMETER As String
Public OPERATION As String
End Class

<System.Xml.Serialization.XmlTypeAttribute([Namespace]:="http://appdev.cincom.com/MantisServer")> _
Public Class REQ_DATE_DESC_FORM
Public year As Decimal
Public month As Decimal
End Class

In a button_onClick event I instantiate an instance of the service (not described here), an instance of REQ_DATE_DESC, an instance of CONTROL and an instance of REQ_DATE_DESC_FORM. I initialize the request value for the input fields, and then assign the CONTROL and REQ_DATE_DESC_FORM instances into their reference variables in REQ_DATE_DESC.
Then I call service.LOOKUP_DATE_DESC with the following statement:

aRspRec = aService.LOOKUP_DATE_DESC(aReqRec)

aRspRec is defined with: Dim aRspRec As localhost.RESP_DATE_DESC_OUT

The definitions for the response classes are:

<System.Xml.Serialization.XmlTypeAttribute([Namespace]:= _
http://appdev.cincom.com/MantisServer")> _
Public Class RESP_DATE_DESC_OUT
Public RESP_DATE_DESC As RESP_DATE_DESC
<System.Xml.Serialization.XmlElementAttribute("CONTROL-RESERVED_INFO")> _
Public CONTROLRESERVED_INFO As CONTROLRESERVED_INFO
<System.Xml.Serialization.XmlAttributeAttribute()> _
Public NAME As String
End Class

<System.Xml.Serialization.XmlTypeAttribute([Namespace]:="http://appdev.cincom.com/MantisServer")> _
Public Class RESP_DATE_DESC
Public resultCode As String
Public resultMessage As String
Public year As Decimal
Public month As Decimal
Public description As String
End Class

<System.Xml.Serialization.XmlTypeAttribute(TypeName:="CONTROL-RESERVED_INFO", -
[Namespace]:="http://appdev.cincom.com/MantisServer")> _
Public Class CONTROLRESERVED_INFO
Public MSG As String
Public INPUT_LINE As String
Public KEYSIM As String
End Class

The LOOKUP_DATE_DESC(aReqRec) returns and instance of aRspRec, but both of the reference variables (RESP_DATE_DESC, CONTOLRESEREVED_INFO,) are “Nothing”; i.e., nil.

The input SOAP message into the LOOKUP_DATE_DESC service looks like this:

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:q0="http://appdev.cincom.com/MantisServer"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<soapenv:Body>
<q0:REQ_DATE_DESC>
<q0:CONTROL>
<q0:NAME>EXAMPLES</q0:NAME>
<q0:CLEARANCE>CASINO</q0:CLEARANCE>
<q0ARAMETER>LOOKUP_DATE_DESC</q0ARAMETER>
</q0:CONTROL>
<q0:REQ_DATE_DESC_FORM>
<q0:year>2010</q0:year>
<q0:month>7</q0:month>
</q0:REQ_DATE_DESC_FORM>
</q0:REQ_DATE_DESC>
</soapenv:Body>
</soapenv:Envelope>

The response SOAP message from the LOOKUP_DATE_DESC service looks like this:

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<soapenv:Body>
<man:RESP_DATE_DESC_OUT xmlns:man="http://appdev.cincom.com/MantisServer"
NAME="RESP_DATE_DESC">
<RESP_DATE_DESC xmlns:ns1="http://appdev.cincom.com/MantisServer">
<resultCode HID="N" LEN="8" PRO="N" TYP="T">Found</resultCode>
<resultMessage HID="N" LEN="100" PRO="N" TYP="T">Description found for
year(2010) month( 7)</resultMessage>
<year HID="N" LEN="4" PRO="N" TYP="B">2010</year>
<month HID="N" LEN="2" PRO="N" TYP="B">7</month>
<description HID="N" LEN="16" PRO="N" TYP="T">July, 2010</description>
</RESP_DATE_DESC>
<CONTROL-RESERVED_INFO xmlns:ns1="http://appdev.cincom.com/MantisServer">
<MSG PRO="Y" />
<INPUT_LINE PRO="N" />
<KEYSIM PRO="N" />
</CONTROL-RESERVED_INFO>
</man:RESP_DATE_DESC_OUT>
</soapenv:Body>
</soapenv:Envelope>

Can anyone tell me what I am doing wrong. If requested to do so, I will post the entire button_onClick method source; I can also post the Web Service WSDL.

Any insight will be greatly apprecieated.

We found the problem. It was in the published WSDL file. The problem was in the schema elementFormDefault= value. It was set to "qualified", which did not work for some reason, but when we changed it to "unqualified" - BANG! - it worked. The new generated proxy class data properties now have "...Schema.XmlSchemaForm.Unqualified"> on all of the declarations. Before this modifier was non-existant.

Anyway, thanks for taking a look everyone.

Consider this question closed.
