C# client cannot connect to Java Web Service

Question

I have a C# .NET client (2.0 Framework) that needs to connect to a java web service (built with Axis) and send some data for processing. The java web service is hosted on a secured Apache server ( I am not in control of this server or web service).

I can create a web reference using VS2005 with the https URL of the WSDL file. When I try sending the data I receive the below error:

"Unable to connect to the remote server"

I added the below function to allow all server certificates.

public static bool ValidateServerCertificate(object sender, X509Certificate certificate, X509Chain chain, SslPolicyErrors sslPolicyErrors)
{
return true;
}

I then make the below call before sending my values to the web service.

ServicePointManager.ServerCertificateValidationCal lback = new RemoteCertificateValidationCallback(ValidateServer Certificate);

I'm not sure if I missed something else or if the problem is not on my end at all.

Any help will be greatly appreciated.

Use following code for secure URL This code is in vb.net Dim certfile As System.Security.Cryptography.X509Certificates.X509Certificate certfile = System.Security.Cryptography.X509Certificates.X509Certificate.CreateFromCertFile(CertificatePath) obj_WebService.ClientCertificates.Add(certfile) obj_WebService is the object of web service. Install the certificate on your computer also If web service uses WS-Security then in the request header you have to send the user id and password also.
