Eu tenho um serviço web NO-.net da oracle Para acessar, preciso adicionar o cabeçalho de sabão. Como posso adicionar o cabeçalho de sabão em java?

Authenticator.setDefault(new ProxyAuthenticator("username", "password"));
                System.getProperties().put("proxySet", "true");
                System.setProperty("http.proxyHost", "IP");
                System.setProperty("http.proxyPort", "port");




                proxy = new RegPresMed_Service(new URL("webservice")).getRegPresMed();
                ((BindingProvider) proxy).getRequestContext().put(BindingProvider.ENDPOINT_ADDRESS_PROPERTY, "realwebservice");
                ((BindingProvider) proxy).getRequestContext().put("com.sun.xml.ws.request.timeout", new Integer(60000));
                ((BindingProvider) proxy).getRequestContext().put(BindingProvider.USERNAME_PROPERTY, "webserviceUsername");
                ((BindingProvider) proxy).getRequestContext().put(BindingProvider.PASSWORD_PROPERTY, "webservicePassword");

isso é necessário?

 ((BindingProvider) proxy).getRequestContext().put(BindingProvider.USERNAME_PROPERTY, "webserviceUsername");
                    ((BindingProvider) proxy).getRequestContext().put(BindingProvider.PASSWORD_PROPERTY, "webservicePassword");

meu cabeçalho de sabão é assim:
