How you created client and how that is being used to make a service call?

[Prasad Shindikar]

I have written a Simple java main method through which i am trying to access the web service.

I have set the proxies correctly to connect from the corporate network.

the location for the wsdl file is : http://www.ebob42.com/cgi-bin/Romulan.exe/wsdl/IRoman

my client code is simple

         URL url = new URL("http://www.ebob42.com/cgi-bin/Romulan.exe/wsdl/IRoman");
        QName qname = new QName("http://eBob42.org/","IRomanservice");
        System.out.println("Creating a service Using: \n\t" + url + " \n\tand " + qname);
        
        ServiceFactory factory = ServiceFactory.newInstance();
        Service remote = factory.createService(url, qname);
 
        System.out.println("Obtaining reference to a proxy object");
        IRoman proxy = (IRoman) remote.getPort(IRoman.class);
        System.out.println("Accessed local proxy: " + proxy);
        String roman = proxy.IntToRoman(42);
        System.out.println("Roman number for 42 is : " + roman);       
  

IRoman is an interface that i defined (from the wsdl), which extends java.rmi.Remote and had the method IntToRoman()

Hope this is helpful.
