CXF Client Security

Question

I am creating a client to a Java soap web service, but am having trouble figuring out how to properly pass the password. Here is my "hardcoded" password example:

@Test
public void exploratorySecurityTest() {
     String username = "user";
     String password = "pwd";

    UserStoryService service = new UserStoryService();
    UserStoryServiceSoap port = service.getUserStoryServiceSoap();

    //initialize security
    org.apache.cxf.endpoint.Client client = ClientProxy.getClient(port); 
    org.apache.cxf.endpoint.Endpoint cxfEndpoint = client.getEndpoint();
    Map<String, Object> outProps = new HashMap<String, Object>();
    outProps.put(WSHandlerConstants.ACTION, WSHandlerConstants.USERNAME_TOKEN);
    outProps.put(WSHandlerConstants.USER, username);
    outProps.put(WSHandlerConstants.PASSWORD_TYPE, WSConstants.PW_TEXT);
    outProps.put(WSHandlerConstants.PW_CALLBACK_CLASS, ClientPasswordCallback.class.getName());
    WSS4JOutInterceptor wssOut = new WSS4JOutInterceptor(outProps);
    cxfEndpoint.getOutInterceptors().add(wssOut);

    int storyId = 33401;
    UserStoryDTO userStoryDTO = port.getByID(storyId);

    //success if no error
}

public class ClientPasswordCallback implements CallbackHandler {

@Override
public void handle(Callback[] callbacks) throws IOException, UnsupportedCallbackException {
    WSPasswordCallback pc = (WSPasswordCallback) callbacks[0];
    pc.setPassword("pwd");
}}

What I really want to do is to pass the password into the callback handler. The examples that I have seen in the CXF documentation implement the callback either "hardcoded" (as I did in this example) or as a function of the username:

if (pc.getIdentifier().equals("user"))
   pc.setPassword("pwd");

Neither of these meet my needs. Is there a way that I can do something like the following:

@Test
public void exploratorySecurityTest() {
     String username = "user";
     String password = "pwd";

    UserStoryService service = new UserStoryService();
    UserStoryServiceSoap port = service.getUserStoryServiceSoap();

    //initialize security
    org.apache.cxf.endpoint.Client client = ClientProxy.getClient(port); 
    org.apache.cxf.endpoint.Endpoint cxfEndpoint = client.getEndpoint();
    Map<String, Object> outProps = new HashMap<String, Object>();
    outProps.put(WSHandlerConstants.ACTION, WSHandlerConstants.USERNAME_TOKEN);
    outProps.put(WSHandlerConstants.USER, username);

            //pass the password here?
            outProps.put("password", password);

    outProps.put(WSHandlerConstants.PASSWORD_TYPE, WSConstants.PW_TEXT);
    outProps.put(WSHandlerConstants.PW_CALLBACK_CLASS, ClientPasswordCallback.class.getName());
    WSS4JOutInterceptor wssOut = new WSS4JOutInterceptor(outProps);

    cxfEndpoint.getOutInterceptors().add(wssOut);
            // ...
}

Use PW_CALLBACK_REF instead PW_CALLBACK_CLASS, and pass an instantiated object, instead of the static class. You can inject the password in said object.

Something like:

    outProps.put(WSHandlerConstants.PASSWORD_TYPE, WSConstants.PW_TEXT);
    CXFClientPasswordHandler handler = new CXFClientPasswordHandler();
    handler.setPassword(password);
    outProps.put(WSHandlerConstants.PW_CALLBACK_REF, handler);
