如何连接到Web服务（启用SSL和代理接口）

Question

There is a web service running on tomcat on a server. It is built on Java Servlet. It is listening others to call itself on a SSL enabled http port. so its web service adreess looks like: https://172.29.12.12/axis/services/XYZClient?wsdl

On the other hand I want to connect the web service above from a windows application which is built on .NET frame work.

Finally, when I want to connect the web service from my computer; I get some specific erros;

Firstly I get; Proxy authentication error; then I added some new line to my code;

   Dim cr As System.Net.NetworkCredential = New System.Net.NetworkCredential("xname", "xsurname", "xdomainname")
        Dim myProxy As New WebProxy("http://mar.xxxyyy.com", True)
        myProxy.Credentials = cr

Secondly, after this modifications It says that bad request. I did not get over this error.

Moreover I did try to connect the web server on the same computer. I copied my executable program to the computer where the web service runs. The error was like;

The underlying connection was closed: Could not establish trust relationship for SSL/TLS secure channel

PS: When I try to connect to web service by using Internet Explorer; I see firstly some warnings about accepting an unknown certificate and I click take me to web service an I get there clearly.

I want to know what are the basic elements to connect a web service, could you please tell me the requirements that I have to use on my windows project.
