Invoking web services via proxy using JAX-RPC and JAX-WS

Invoking Web Services through a proxy using JAX-WS

  MyService service = null;
    service = new MyService();

    MyServiceSoap port = service.getMyServiceSoap();
    BindingProvider bp = (BindingProvider) port;
    Binding binding = bp.getBinding();

    Map ctx = bp.getRequestContext();
    ctx.put(BindingProvider.USERNAME_PROPERTY, "proxyuser");
    ctx.put(BindingProvider.PASSWORD_PROPERTY, "proxypassword");

Note that we don't specify the Proxy Server here. JAX-WS sends authentication information for the proxy in request headers.

    private HttpTransportInfo getHttpInfo() {
    Proxy proxy = new Proxy(Proxy.Type.HTTP, new InetSocketAddress("proxyServer", 9090));
    HttpTransportInfo httpInfo = new HttpTransportInfo();
    httpInfo.setProxy(proxy);

    httpInfo.setProxyUsername("proxyuser".getBytes());
    httpInfo.setProxyPassword("proxypassword".getBytes());
    return httpInfo;
  }
