WSDL SOAP using SSL in VB.NET application

new to WSDL SOAP using SSL in vb.net Application, having trouble integrating.

What I have tried:

Hi, I am new to WSDL and soap, I need to integrate a device, we were provided a WSDL file and a .jks file which I think is for SSL certificate. I have successfully referenced the WSDL, but after that I don't have any idea what to do especially like where do I put the IP address and port of the device and all. How do I send it using SSL?

Any help would be very much appreciated.

Thanks

Solution 1

First of all...I do not think .NET can handle jks files as source of certificate... you need pfx files...
See here one options how to convert between the two or connect the device vendor for one... Create a PKCS12 (.pfx / .p12) from a JKS / JAVA keystore[^]

As for the WSDL...The moment you referenced[^] VS created a wrapper class using the name you assigned to the reference...
Using that class name you can create an object and call all the exposed methods of the web server...

C#

WebReference service = new WebReference();

X509Certificate2 cert = new X509Certificate2();
cert.Import("client_cert.pfx", "[the password]", DefaultKeySet);

service.Url = "[the actual server address]";

service.ClientCertificates.Add(cert);

service.Method();

(Sorry. Just realized you asked for VB.NET... The difference is only in the language syntax...)

[EDIT]
According to your comments...
You can reference a WSDL in two ways: Web Reference (older) and Service Reference (newer)... In each case there are different ways to set the target address...
For Web Reference:

C#

WebReference.OSAccessService oA = new WebReference.OSAccessService( );
oA.Url = "address-goes-here";

For Service Reference:

C#

ServiceReference.OSAccessClient oB = new ServiceReference.OSAccessClient( );
oB.Endpoint.Address = new System.ServiceModel.EndpointAddress( "address-goes-here" );

Hello, thanks for the quick reply.
Itried your solution problem is "service.url" and "service.ClientCertificates.Add(cert)" of web reference is recongized, is it possible there is something wrong with the WSDL file that they gave me?

Kornfeld Eliyahu Peter 9-Nov-16 4:12am

Not likely... Maybe the way you referenced it is wrong?
Can we point us to the WSDL? Is it public?

sampos 9-Nov-16 21:37pm

No, it's local WSDL file that they gave me. Is there a way for me to send the file to you privately?

Thanks

Hi again, this is the link to the file: https://dl.dropboxusercontent.com/u/18176784/Client.wsdl

Hope you can check it and provide a feedback on what am I doing wrong.
Thanks again.

The WSDL perfectly OK... It seems you used it as a Service Reference, while I used it as a Web Reference...
See updated answer for differences...

Thanks so much sir, another question, with your directions, i arrived with this code:

X509Certificate2 cert = new X509Certificate2();
cert.Import("client_cert.pfx", "[the password]", X509KeyStorageFlags.DefaultKeySet);

ServiceReference1.OSAccessClient oB = new ServiceReference1.OSAccessClient( );

X509Store store=new X509Store(StoreName.My, StoreLocation.CurrentUser) ;
store.Open(OpenFlags.ReadWrite);

oB.Endpoint.Address = new System.ServiceModel.EndpointAddress( "address-goes-here" );
store.Add(cert);

Is this correct?

then to call a function of WSDl, I just use something like oB.AddONT()?

Kornfeld Eliyahu Peter 22-Nov-16 5:02am

Yes and yes.
It seems correct and you simply call the member method, the rest is done by the reference wrapper...

sampos 23-Nov-16 3:39am

Thanks so much. By the way, when I called the member method like oB.AddONT(OS_Header), what does the OS_Header parameter mean/do? What do I put there?

Hi sorry, I am still having a problem with this, a line was giving me an error of "Object reference not set to an instance of an object.", my code is:

Dim cert As New X509Certificate2

cert.Import("client.p12", "Changeme_123", X509KeyStorageFlags.DefaultKeySet)

Dim oB As New ServiceReference1.OSAccessClient

Dim store As X509Store = New X509Store(StoreName.My, StoreLocation.CurrentUser)

store.Open(OpenFlags.ReadWrite)

oB.Endpoint.Address = New System.ServiceModel.EndpointAddress("http://1.1.1.2:55555/wsdl")
store.Add(cert)

Dim AX As ServiceReference1.ADDONT_T = New ServiceReference1.ADDONT_T

AX.object.DEV = "dfgdfgdf" ------> This is where i get an error of "Object reference not set to an instance of an object."

oB.ADDONT("", AX)

oB.Close()

I think AX needs to initilize a connection, I'm just not sure how?
