Hello.

I am writing a cxf client and trying to use a username/password secutiry so
i am adding the WSS4JOutInterceptor to the interceptors chain but on
execution it gives me a NullPointerException.

Relevant Stack :
Caused by: java.lang.NullPointerException

the code:

        Map<String, Object> outProps = new HashMap<String, Object>();
        outProps.put(WSHandlerConstants.ACTION,
WSHandlerConstants.USERNAME_TOKEN);
        outProps.put(WSHandlerConstants.USER, usuarioPassword[0]);
        outProps.put(WSHandlerConstants.PASSWORD_TYPE, WSConstants.PW_TEXT);
        CallbackHandler callback = new CallbackHandler() {

            public void handle(Callback[] callbacks) throws IOException,
UnsupportedCallbackException {
                WSPasswordCallback pc = (WSPasswordCallback) callbacks[0];

                // set the password for our message.
                pc.setPassword("ThePassword");

            }
        };
        outProps.put(WSHandlerConstants.PW_CALLBACK_REF, callback);

        WSS4JOutInterceptor wssOut = new WSS4JOutInterceptor(outProps);
        clientEndPoint.getOutInterceptors().add(wssOut);


        respuesta = myWebService.ejecuta(abono);

Using: CXF 2.1.3 over Weblogic 10.3

I have seen this error reported but have not found any working solution.

Any help would be appreciated.

Thanks
