Get trough Authentification in ASP.NET for a Domino WebService

Posted on 2008-10-23

Last Modified: 2013-11-17
I'm building a webservice in Domino designer that acces a lotus notes database. (we are on Ver. 7)

I want to consume that web service in ASP.net.
Whe i use a get method, i got a "Client found response content type of 'text/html; charset=UTF-8', but expected 'text/xml'."

I guess it's because i got to pass trough the Authentification process because when i go to the ?WSDL page, i got the "Log in to Sametime" page (the same that when i go to to out mail web access).
So i guess that is the 'text/html" response?
How could i provide a user/password to the webservice or another workaround?

This article might help but I think you have to have basic authentication


We use session authentication and I never really got it working but I was just playing around.

Well, I got my sysadmin add an rule and he said he restarted the HTTP part of the server, but it still not working. (I mean passing Credential to the service)
Now, I m trying to pass an cookie to the service but it dosen t work.
Does someone got an example working for notes?
I scroll down on the first link you provided me, and saw information that i thought useful, but i still cant get it work...
I need help!

i thibk i now know why i was missing some reference.
I m using Visual web developer 2008 (express)
When I Add a webreference, I dont get a "reference.vb" file.
is it what i was missing?
Should i make the switch to Visual Studio or there is a way to do it with Visual web developer?

I believe the reference.vb proxy class file is only for winforms applications and not relevant on asp.net pages.

I'll see if I can dig up my old project and get it working with the override rule

I did it!
I found a way to get the authentication cookie and forward it to the webservice!
I use the link i provided + the one brwwiggins provided me in the first place.
I asked my sysadmin to remove the rule so i could confirm it work using session authentication.
Here my code!

Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim QSWEBService As New WEBService()
        'connect to the service the first time
        Dim webRequest As Net.HttpWebRequest
        webRequest = Net.HttpWebRequest.Create(QSWEBService.Url)
        Dim responseReader As System.IO.StreamReader = New System.IO.StreamReader(webRequest.GetResponse().GetResponseStream())
        Dim responseData As String = responseReader.ReadToEnd()
        'have a cookie container ready to receive the forms auth cookie
        Dim cookies As System.Net.CookieContainer = New System.Net.CookieContainer()
        'construct the data to post
        Dim postDataByte As Byte()
        Dim userName As String = "myUserName"
        Dim password As String = "MyPassword"
        'enncode the form data string into a byte array 
        postDataByte = System.Text.Encoding.ASCII.GetBytes("username=" & userName & "&password=" & password)
        'indicate that you will be posting the data 
        Dim LOGIN_URL As String = "http://www.myurl.com/names.nsf?Login&&RedirectTo=" & QSWEBService.Url
        webRequest = Net.HttpWebRequest.Create(LOGIN_URL)
        webRequest.Method = "POST"
        webRequest.ContentType = "application/x-www-form-urlencoded"
        webRequest.AllowAutoRedirect = False
        webRequest.CookieContainer = cookies
        'write the form values into the request message
        Dim postStream As System.IO.Stream = webRequest.GetRequestStream()
        postStream.Write(postDataByte, 0, postDataByte.Length)
        ' Close the post
        'we don't need the contents of the response, just the cookie it issues
        'This code is in case we want to get it (debugging) 
        'responseReader = New System.IO.StreamReader(webRequest.GetResponse().GetResponseStream())
        'responseData = responseReader.ReadToEnd()
        'now we can send out cookie to the protected WEBService
        QSWEBService.CookieContainer = cookies
        QSWEBService.PreAuthenticate = True
        Dim test As string
        test = QSWEBService.GetTest()        
        Label1.Text = test
End Sub
