Consuming a web service with Classic ASP

Hi everyone,

I've been trying for about 2 hours to figure out why I get the following error when I try to consume a web service located at another site:

Could not create an object of type 'MSSOAP.SoapClient'.

The site works great on all my machines here however once I upload it to discountasp.net, I receive the error above.

Below is some test code I use to consume the web service:

Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
Try
Dim s As String

Dim ds As New Data.DataSet
'Using classic asp code because the URL can change from agency to agency
Dim objSoapClient = Server.CreateObject("MSSOAP.SoapClient")
objSoapClient.ClientProperty("ServerHTTPRequest") = True

'needs to be updated with the url of the Web Service WSDL and is
'followed by the Web Service name
Call objSoapClient.mssoapinit(txtURL.Text)

'using the SOAP object to call the Web Method Required
'Since we don't have access to this data, we will have to pass
'username and password provided by the agency

s = objSoapClient.VendorQuery(txtVendorID.Text, txtAgencyKey.Text, txtReportNumber.Text, txtParameterString.Text)
'create an instance of the object containing the deserialized object
Dim x As System.Xml.Serialization.XmlSerializer = New System.Xml.Serialization.XmlSerializer(ds.GetType)
'read the serialized string
Dim sr As New IO.StringReader(s)
'deserialize and cast the object into the dataset
ds = CType(x.Deserialize(sr), Data.DataSet)

GridView1.Visible = True
Label1.Text = Nothing

GridView1.DataSource = ds
GridView1.DataBind()
Catch ex As Exception
GridView1.Visible = False
Label1.Text = ex.Message
End Try
End Sub

 

Btw, I downloaded and installed the SOAP ToolKit 3.0 so this line should be changed from:

Dim objSoapClient = Server.CreateObject("MSSOAP.SoapClient")

to

Dim objSoapClient = Server.CreateObject("MSSOAP.SoapClient30")

I'm thinking that the toolkit isn't installed on the server, hmmmm

 

...I would have to agree with that but I do not know for sure. ;-)
You might want to open a support ticket to check.
All the best,
Mark

 

Thanks wisemx, I'll do that now. I'm sure that's it. It wouldn't hurt to have it installed on the server anyhow as there are still a vast number of sites that use that technology.
