[RESOLVED][02/03] Moving web service issues

I now have code working that calls a web service on our development environment. I then rebuilt just that project which had the Web Reference folder within it. I moved the .dll's and also the Web Reference as is and then copied to the production server. I now get, "Not Authorized" errors in production code.

Any thoughts if there are other settings I have to change or is there a way to resetup the Web Service on the production server?

There are the files in my Web Reference folder:
Web References
- DflImagingService
- ImagingService.disco
- ImagingService.wsdl
- Reference.map

Thanks in advance.

I can't understand... when do you get the 'not authorized' error? Is that the exact error? Do you get it when you access the site or when you access the web service?

If it's when you access the website, then check your IIS settings, ensuring that anonymous or windows authentication is enabled (whatever you're supposed to be using, that is).

I get it when I access the web service. I know it's erroring is because the following line writes to a log file:
Log2File("Web Service Error: " & result.Exceptions(i) & " ")

On my development server where I added the Web Service it doesn't error.

Code:

---

Dim imagingService As DflImagingService.ImagingService = Nothing
            Dim results As DflImagingService.ImageResult() = Nothing
            Dim credentials As DflImagingService.Credentials = Nothing
            Dim fileStream As fileStream = Nothing
            Dim pro As Long = 0
            pro = CType(PRONumber, Long)
            Dim ctr As Integer = 0

            Try
                ' Instantiate the web service objects.
                imagingService = New DflImagingService.ImagingService()
                credentials = New DflImagingService.Credentials()
                ' Set username/password properties of credentials object.
                credentials.UserName = m_sUsername
                credentials.Password = m_sPassword

                ' Set the credentials property of the imaging service to your credentials object.
                imagingService.CredentialsValue = credentials
                ' Call the TrackByDate() web method.
                results = imagingService.GetImages(pro)
             
                Dim result As DflImagingService.ImageResult
                For Each result In results
                    If result.Exceptions Is Nothing Then
                        If result.DocumentType = "DELIVERY RECEIPT" Then
                           
                            ' Do something w/ image data.
                           
                            fileStream = New fileStream(DownloadPath, FileMode.Create)
                            fileStream.Write(result.ImageData, 0, result.ImageData.Length)
                            fileStream.Seek(0, SeekOrigin.Begin)
                            fileStream.Close()
                            bReturn = True
                        End If
                    Else
                        Dim i As Integer
                        For i = 0 To result.Exceptions.Length - 1

                            Log2File("Web Service Error: " & result.Exceptions(i) & " ")
                         
                        Next
                    End If
                    ctr += 1
                Next
            Catch soapException As System.Web.Services.Protocols.SoapException
                Dim webServiceExceptions As WebServiceException() = ParseSoapException(soapException)

                Dim stringBuilder As New stringBuilder()
                Dim i As Integer
                For i = 0 To webServiceExceptions.Length - 1
                    stringBuilder.Append(webServiceExceptions(i).Message & vbCr & vbLf)
                Next
                Throw New Exception(stringBuilder.ToString())
            Finally
                If Not (imagingService Is Nothing) Then
                    imagingService.Dispose()
                End If
                imagingService = Nothing
                credentials = Nothing
                If Not (fileStream Is Nothing) Then
                    fileStream.Close()
                End If
                fileStream = Nothing
            End Try

So what is the exact error message?

Based on vague information, you'll probably need to check the security settings on the virtual directory or website hosting the web service. It could be a setting at an IIS level blocking the call or it could be the username and password you are passing through.

The exact errors are:

Not Authorized
Not Authorized
Not Authorized
Not Authorized
Not Authorized

That's it based on the loop.

I will check the settings. It's not the u/p since I wrote those to the same log and matched the development u/p.

Do you know what exact setting could cause this?

Can we change this thread to vb.net?

I ran a test by just putting this web service code in a new web project and then moved to same production server. Works like a charm.

So the new question is, using a web service in vb.net different then asp.net? The funny thing is why does it work on my development server.

Frustrating.

From past experience, here is what I know usually happens:

You create a web service on your machine which creates a virtual directory on your machine with the default of 'windows authentication' checked.

Same goes for a web application.

Now in many cases, even on test servers/production servers, the new virtual directory created for a web service has windows authentication checked.

When you run an application in debug mode, it runs under your security credentials. So I'm not talking about the username/password in code, I mean the windows domain credentials that you used to log on.

A windows form application always runs under the security credentials of the current user which is why the web service call from there worked for you.

At this point, you need to verify if windows authentication is checked in the directory security settings in your virtual directory on the production and test servers. If it is, then you probably don't need it, get rid of it.
