Trying to consume Coldfusion Web Service using VB.NET

May 27th, 2008

Hi all,

I'm trying to consume a Service called GetMemberPointsAvailable using VB.NET. Here is the wsdl: http://sp-s3g-uat.iclp.com.au/ws/ega...egapi.cfc?wsdl

This service is written in coldfusion - axis engine.

The steps:
I'm using VB.net on Visual Studio 2005. I created a new windows application project.

Then I added a web reference with URL http://sp-s3g-uat.iclp.com.au/ws/ega...egapi.cfc?wsdl and named the reference as webserviceICLP

Then i added a button on my form and put the following code on the button click event:

 Help with Code Tags 
 VB.NET Syntax (Toggle Plain Text) 
Dim client As New webserviceICLP.SportingWS '(or egapiClient in VB2008) 
For Each item As webserviceICLP.mapItem In client.getMemberPointsAvailable("xxxxx", "yyyy", "123456789") 
MsgBox(item.key & vbNewLine & item.value) 
Next
Dim client As New webserviceICLP.SportingWS '(or egapiClient in VB2008) 
For Each item As webserviceICLP.mapItem In client.getMemberPointsAvailable("xxxxx", "yyyy", "123456789") 
MsgBox(item.key & vbNewLine & item.value) 
Next

It does nothing because (i think) there are no item created by the response of the webservice.
Also i tried to serialize the returning webservice message object using the following code:

Dim wsICLP As New webserviceICLP.SportingWS 
Dim MyParams() As webserviceICLP.mapItem = {New webserviceICLP.mapItem} 
MyParams = wsICLP.getMemberPointsAvailable("xxxxx", "yyyy", "123456789") 
MsgBox(SerializeToXML(MyParams)) 
Public Shared Function SerializeToXML(Of T)(ByVal obj As T) As String 
Dim returnXML As String = String.Empty 
Dim serializer As New Serialization.XmlSerializer(GetType(T)) 
Using writer As New IO.StringWriter 
serializer.Serialize(New XmlTextWriter(writer), obj) 
returnXML = writer.ToString() 
End Using 
Return returnXML 
End Function
Dim wsICLP As New webserviceICLP.SportingWS 
Dim MyParams() As webserviceICLP.mapItem = {New webserviceICLP.mapItem} 
MyParams = wsICLP.getMemberPointsAvailable("xxxxx", "yyyy", "123456789") 
MsgBox(SerializeToXML(MyParams)) 
Public Shared Function SerializeToXML(Of T)(ByVal obj As T) As String 
Dim returnXML As String = String.Empty 
Dim serializer As New Serialization.XmlSerializer(GetType(T)) 
Using writer As New IO.StringWriter 
serializer.Serialize(New XmlTextWriter(writer), obj) 
returnXML = writer.ToString() 
End Using 
Return returnXML 
End Function

and the result I get is :

 Help with Code Tags 
 XML Syntax (Toggle Plain Text) 
<?xml version="1.0" encoding="utf-16"?><ArrayOfMapItem xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" />
<?xml version="1.0" encoding="utf-16"?><ArrayOfMapItem xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" />

I know that the webservice is running because i tried to test it with the Soap UI tool and it did Ok. Here's the reponse of the WS:

Any help would be much appreciated!

All the best,
