Invoking Secure .asmx webservice from Java

Question

I have a webservice whose url is something like this:

http://pc212323/AdminService/HelloWorldService.asmx?wsdl

Now when i hit this service from soapUI it asks for Username, Password in a saperate popup window. This is done before soapUI loads the request structure. Again then i have to pass Username and password in the Request Properties present on the left of SoapUI tool. Then it gives me the output.

Now i want to hit this asmx sevice through java but am unable to figure out how to invoke this service by passing username and password.

In short i want to replicate this behaviour of soapUI through java code

Looking forward to your answers. Thanks in advance.

I am invoking the above service with this code of mine:

                                } catch (AxisFault e) {
                                                e.printStackTrace();
                                }
                }

}

But i am getting error as:
