The username and password is given correct what the problem Please help me any body

Show the code you're using to call this. How is it referenced?

Did you look at the http://java/web/service?wsdl as well?

Thanks for your Reply
These are the steps followed to add reference
URL: http://billing.rephero.com/jboss-net...s/billing?wsdl prompts for “Axis basic authentication” the screen looks as below

Step 2: in Axis basic authentication dilog box i entered username and password and clicked ok after that it asks for some confirmation

Step 3: Confirmation message is “The server need to authenticate your credentials will be sent to the server in clear “text”

Step 4: After confirming yes am getting “discovery credentials” dialog box It accepts username password and domain name. If i give domain name reference is not getting added but without giving a domain name if clicked Ok then it adds reference successfully.

This is what the code we are using to invoke the jBilling functions

Code:

---

Imports JBillingWebReff
Imports com.rephero.billing
Imports com.rephero.billing.UserWS

Partial Class JBillingWebReff
Inherits System.Web.UI.Page
Dim service As New WebServicesSessionLocalService()

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Dim userId As Integer = service.getUserId("Web")
If userId > 0 Then
Dim userData As UserWS = service.getUserWS(userId)
End If
End Sub
End Class

Thank you

Vuyiswa

You may need to pass the credentials...

service.Credentials = New NetworkCredentials(........)

ya but i don no how to add credentials can u please help how to add credentials
one thing the web service is in different server but am working in another server so
and am not directly working in server
just developing the code and uploading the component to server

I just showed you. You should be able to set the .Credentials property.

service.Credentials = new NetworkCredentials("user", "pass")

I think the service is not supporting for http: let me check.
but thanks u again


Thanks

A 505 is supposed to contain the reason for not supporting the request. Oh well, that's the world of Java for you. Start stepping through your code. Find out which line the code errors out on. Is it getUserId() or getUserWs?

hi mendhak

i think it is the error am getting becouse the service is not Supporting here the document they have given

Notice that there is already a section to force HTTPS, but it is commented. Uncomment
the section to force HTTPS:
<!--
This is needed to secure web service over SSL
<user-data-constraint>
<transport-guarantee>CONFIDENTIAL</transport-guarantee>
</user-data-constraint>
-->
It will use the SSL certificate that tomcat is using to secure the standard web client.


Thanks

hi Sir
I Checked in https but their also am getting same error

when I remove all the code except credential then I did not get any error after that I changed my privies code to

Imports JBillingWebReff
Imports com.rephero.billing
Imports com.rephero.billing.UserWS
Imports com.rephero.billing.WebServicesSessionLocalService

Partial Class JBillingWebReff
Inherits System.Web.UI.Page

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Dim service As WebServicesSessionLocalService = New WebServicesSessionLocalService()
Dim userName As String = "jbajin"
service.Credentials = New Net.NetworkCredential("webapp", "r3ph3r0-b1ll1ng")
Dim userIdParams As String = "jbajin"
Dim result As String
result = service.getUserId(userIdParams)

Response.Write(result)

End Sub
End Class


this is first time am working with this type of web service(java) please help me

Hmm, looking at the wsdl, I see that it's not SOAP, which is the method that you're attempting to reference. It's got complexTypes. Thank goodness for standards.

I am not sure why you are getting those specific errors, but from what I can tell, you will not be able to reference the web service and use it in your application like this.

I did try using the wsdl utility to do this. I've attached the output I got.

My command was

Code:

---

C:\Program Files\Microsoft Visual Studio 8\VC>wsdl.exe http://billing.rephero.com/jboss-net/services/billing?wsdl /out:c:\myaxis.cs /username:XXXXXXXXX /password:XXXXXXXXXXXXXX > c:\output.txt

---

I've attached the output generated by the tool as well as the proxy class generated.
