I can't find any reference to this error:

Run-time error '5054'
Method 'EndMessage' of object 'ISoapConnector' failed


background: I went through the MS Soap 3 tutes, now i'm trying to set up a soap service with one of my active x exe's. did the wgen on it. now i'm setting up a vb6 client to test. basically, used the tutorial test client as a base and added my stuff in. here is some the code for the test client:


Private Function GetImage(ByVal Method As String, ByVal CatalogID As String, ByVal ItemNum As String, _
            ByVal TheStyle As String, ByVal ColorDes As String, ByVal TheText1 As String, ByVal TheText2 As String)

    Dim Serializer As SoapSerializer30
    Dim Reader As SoapReader30
    Dim ResultElm As IXMLDOMElement
    Dim FaultElm As IXMLDOMElement
    Dim Connector As SoapConnector30
    
    Set Connector = New httpConnector30
    Connector.Property("EndPointURL") = END_POINT_URL
    Connector.Connect
    
    ' binding/operation/soapoperation
    Connector.Property("SoapAction") = SoapAction & Method
    Connector.BeginMessage
    
    Set Serializer = New SoapSerializer30
    Serializer.Init Connector.InputStream
    
    Serializer.StartEnvelope
    Serializer.StartBody
    Serializer.StartElement Method, CREATE_GRAPHIC
    Serializer.StartElement "strCatID"
    Serializer.WriteString CatalogID
    Serializer.EndElement
    Serializer.StartElement "strItemNo"
    Serializer.WriteString ItemNum
    Serializer.EndElement
    Serializer.StartElement "strStyle"
    Serializer.WriteString TheStyle
    Serializer.EndElement
    Serializer.StartElement "strColorDesc"
    Serializer.WriteString ColorDes
    Serializer.EndElement
    Serializer.StartElement "strText1"
    Serializer.WriteString TheText1
    Serializer.EndElement
    Serializer.StartElement "strText2"
    Serializer.WriteString TheText2
    Serializer.EndElement
    Serializer.EndElement
    Serializer.EndBody
    Serializer.EndEnvelope
    
    Connector.EndMessage    '<--- LINE THAT IT FAILS ON
        
    Set Reader = New SoapReader30
    Reader.Load Connector.OutputStream
    
    If Not Reader.Fault Is Nothing Then
        MsgBox Reader.FaultString.Text, vbExclamation
    Else
        GetImage = Reader.RpcResult.Text
    End If
End Function


can anyone lend me a hand here?

ok, solved that error by changing my endpointurl to the asp listener instead of the wsdl file. but now i have a new error:


"WSDLReader:The operation requested in the Soap message with soapAction http://tempuri.org/sartpreviewws/SARTPreviewServer/SartPreview.CreateGraphics isn't defined in the WSDL file.  This may be because it is in the wrong namespace or has incorrect cae"


here is my soapAction declaration:

Private Const SoapAction = "http://tempuri.org/sartpreviewws/SARTPreviewServer/SartPreview."

it is put together in Connector.Property("SoapAction") = SoapAction & Method with the passed in method parameter (above function)

i'm a little lost, trying to learn this. here is my wsdl file:

i noticed the this line in the "operation" declaration - <input message='wsdlns:CreatePreview.CreateGraphics'/> and tried to use that namespace(?) but still got the same error.

so now what?

Check to make sure that the Connector.Property("EndPointURL") points to a web page that has the reference to the DLL that is doing the "work".

When the web page is not there you can get this message.

Were you able to get around the problem "WSDLReader:The operation requested in the Soap message with soapAction". If so, can you please explain me how you did it. I am having the same problem.

i'm trying to remember but i think it was because the host provider didn't have the latest soap toolkit installed. they wouldn't install it either. so i had to take a different route with the MS XMLHTTP object (which was there).
