making a SOAP connection persist

[cj]

I've been trying all week to write a VB.net soap client. I've finally
gotten a connection after figuring out I needed to change the name of a
..xml file I was given to .wsdl and add it as a web reference in my
Windows app. When I click button2 to logout I get an error message and
the folks at the company I'm connecting to say I need to set my session
to persist. They can not tell me how to do this as they are non-MS Java
developers. Here is my code. They've verified what I'm sending in the
variable soapmesg is correct. ANY help is appreciated.

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles Button1.Click
TextBox1.Text = ""
Button1.Enabled = False
Dim proxy As New voi.voi_web_server
Dim soapmesg As String
Dim respstr As String
Dim sessionKey As String
soapmesg = "<?xml version=""1.0"" encoding=""ISO-8859-1"" ?>" & _
"<cardtel_request>" & _
"<login>******</login>" & _
"<password>******</password>" & _
"</cardtel_request>"
respstr = proxy.validate(soapmesg).ToString()
sessionKey = respstr.Substring(11)

TextBox1.Text = respstr
TextBox2.Text = sessionKey

Button1.Enabled = True
End Sub

Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles Button2.Click
TextBox2.Text = ""
Button2.Enabled = False
Dim proxy As New voi.voi_web_server
Dim soapmesg As String
Dim respstr As String
soapmesg = "<?xml version=""1.0"" encoding=""ISO-8859-1"" ?>" & _
"<cardtel_request>" & _
"<stop>stop</stop>" & _
"</cardtel_request>"
respstr = proxy.validate(soapmesg).ToString()

TextBox1.Text = respstr
TextBox2.Text = ""

Button2.Enabled = True
End Sub

Welcome Cj,

Seems the webservice you're trying to cosuming is not quite simple. From
your description the service side ask you to persist the session, I think
this means that when you first time call the service and login the service,
it will return some data represent the authenticated ticket. Then, in the
sequential requests, you need to use this ticket to perform other
operations, I'm not sure how it require you to attach the ticket, is there
any further info or specification about the server-side service's
communiation interface?

Hi Steven,

Right now I'd be happy to login and logout w/o doing any business.

Login works. When I login I receive the session key

soapmesg = "<?xml version=""1.0"" encoding=""ISO-8859-1"" ?>" & _
"<cardtel_request>" & _
"<login>******</login>" & _
"<password>******</password>" & _
"</cardtel_request>"

respstr = proxy.validate(soapmesg).ToString()
sessionKey = respstr.Substring(11)

but apparently it's not sent in the logout. When I asked the
programmers on the server side what to send to logout this is what they
emailed me back.

You send the following XML:

<cardtel_request><stop>stop</stop></cardtel_request>

the session information kept in the SOAP headers will tell the
server what session to terminate.

When I told them it wasn't working they told me:

My server doesn't know that your logoff xml is part of a current
session.

This is where you need to figure out how to tell you client to
keep a persistent connection with my server.

Remember they don't know .net. They do non-MS Java development. So I'm
hoping someone here can help me figure this out.

Thank for the help Steven. I have it logging in and out now. I'll post
again when I have another question. Shouldn't be too long. :)
