Problem deploying wcf service to web host

[NewsBot]

Hi all, new here and a realative newbie to some things I'm learning in VS2008 and .NET.

 

After finding that a wcf service I wrote wouldn;t run when I deployed it to my web site (was fine on my development system) I decided to try*a most trivial example of a method that returns a string.* Still wouldn't run when deployed to web.

 

Wondering if it had something to do with credientials, I changed wsHttpBindings to basicHttpBindings.* Same result.* Then I*implemented a custom validator class, and on my machine it is using that valiator fine, using UserName as clientCredentialType, and the service behaves as I woudl predict.* But I am getting one exception all the time from the web-deployed channel...

 

999 No hacking.

 

What's weird, searches on web give me not one reference to that error.* The stack trace in this present incarnation, using a custom validator, basicHttpBindings etc is simply...

 

at System.Net.HttpWebRequest.GetResponse()

** at System.ServiceModel.Channels.HttpChannelFactory.HttpRequestChannel.HttpChannelRequest.WaitForReply(TimeSpan timeout)

 

Can anyone suggest possible reasons*that services running fine on my devleopment system are continually throwing this error when deployed to web?

 

By the way, the means I am using of testing is a simple form, the code something like..

 

----

 

Private client As New ServiceReference2.Service1Client

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

Try

'client.InnerChannel.Open()

client.ClientCredentials.UserName.UserName = "blahblah"

client.ClientCredentials.UserName.Password = "etcetc"

Me.Label1.Text = client.GetData(1)

Catch ex As Exception

 

End Try

-----

 

The name and password are handled by my custom validator, and on my development system this is defintely working OK.*

 

Any pointers to possibilities greatly appreciated.

David
