Re: Calling J2EE web service from .NET

When I run my Java test, according to netmon, the HTTP header of the request
contains a "Basic Authentication" section with the realm containing a UserId
and PassWord. When I make the call from VB in .NET, however, the HTTP header
does not contain the "Basic Authentication" at all. How do I get it to
include it? I've tried the following code as well, but to no avail.

Dim ws As New WSRef.X_WS
Dim oper As New WSRef.myOper
Dim cred As New System.Net.NetworkCredential("username", "password")
Dim u As New Uri(ws.Url)
Dim icred As System.Net.ICredentials = cred.GetCredential(u, "Basic")

ws.Credentials = icred

Dim resp As WSRef.myMethodResponse = myWS.myOper(oper)

I implemented a J2EE web service on Sun's Application Server 8. The web
service is set up to require BASIC authentication. I created a Java
client
that passes credenttials for the authentication and all went well.

I then tried to add a web reference to a client project in .NET using VB.
My code is essentially (WSRef is the name of my added web service
reference):

Dim ws As New WSRef.X_WS
Dim oper As New WSRef.myOper
Dim cred As New System.Net.NetworkCredential("username", "password")

ws.Credentials = cred

Dim resp As WSRef.myMethodResponse = myWS.myOper(oper)

When the code runs it gets back the following error:

ERROR:

System.Net.WebException: The request failed with HTTP status 401:
Unauthorized.

at
System.Web.Services.Protocols.SoapHttpClientProtocol.ReadResponse(SoapClientMessage
message, WebResponse response, Stream responseStream, Boolean asyncCall)

at System.Web.Services.Protocols.SoapHttpClientProtocol.Invoke(String
methodName, Object[] parameters)
...

The given user name and password should work and do using a Java client.
Any idea what might be causing this?

I'd recommend you use a network analyzer such as Microsoft Netmon (see their
blog at http://blogs.technet.com/netmon/). Look at the wire and see how it
looks when it fails and when it succeeds and see what's different.
