JAX-WS Password Type PasswordText

I've got a simple command line Java JAX-WS app to test a SOAP request, but the server is expecting the Password Type to be PasswordText and I'm stumped on how to set this...

The code looks like so:

@WebServiceRef
private static final HelloService helloService = new HelloService(url, new QName(
        URL, "HelloService"));

public static void main(final String... args) {

    try {
        final HelloPort helloPort = helloService.getHelloPort();
        final BindingProvider hB = ((BindingProvider) helloPort);
        hB.getRequestContext().put(BindingProvider.ENDPOINT_ADDRESS_PROPERTY,
                                   END_POINT_ADDRESS);
        hB.getRequestContext().put(BindingProvider.USERNAME_PROPERTY,
                                   USERNAME);
        hB.getRequestContext().put(BindingProvider.PASSWORD_PROPERTY,
                                   PASSWORD);
        ...

I've tested the request using SOAP-UI so I know it's working. Any help on setting the password type would be appreciated.

Thanks.
