How to supply username/password and hostname when calling a web service

Question

The Workshop Help contains a chapter named "To Use the Java Proxy in a Separate Java Application". It includes the following code:
public class Main
public static void main(String[] args)
try
HelloWorld_Impl proxy = new HelloWorld_Impl();
HelloWorldSoap soapProxy = proxy.getHelloWorldSoap();
System.out.println(soapProxy.Hello());
catch (Exception e)
e.printStackTrace();
Questions:
1. How is the username and password supplied in case the Hello World web service is secured?
(I have not found any Javadoc for weblogic.webservice.core.rpc.ServiceImpl, but from the code assist I see a constructor taking two Strings....)
2. Is there a way to supply a hostname, and port, in case the Hello World web service exists on more than one host?

Answer 1

If I need to specify the wsdl url it fails as wsdl it self is protected. How do I pass in the userId/password while getting the wsdl.
E.g:
/*Line below fails as userId/password is not passed.*/
HelloWorld_Impl proxy = new HelloWorld_Impl(wsdlLocation);
HelloWorldSoap soapProxy = proxy.getHelloWorldSoap("username", "passwd");
System.out.println(soapProxy.Hello());
