java.net.SocketTimeoutException: connect timed out + google directory , admin sdk API

Try the following ...

1. Set the proxy in the linux box.
2. While creating storage - new NetHttpTransport() provide your own way to create the socket and add the proxy in the transport.

Example code ...

public HttpClient myHttpClient() throws Exception {

        SchemeRegistry schemeRegistry = new SchemeRegistry();
        //SetRegisrty for both HTTP and HTTPS - Check google for this.
        schemeRegistry.register(new Scheme("http", PlainSocketFactory
                .getSocketFactory(), YOUR_PROXY_PORT));
        schemeRegistry.register(new Scheme("https", SSLSocketFactory
                .getSocketFactory(), 443));

        HttpParams params = new BasicHttpParams();
        HttpConnectionParams.setConnectionTimeout(params, 30 * 1000);  // SET the timeout
        HttpProtocolParams.setVersion(params, HttpVersion.HTTP_1_1);
        ClientConnectionManager connManager = new ThreadSafeClientConnManager(
                params, schemeRegistry);
        DefaultHttpClient httpClient = new DefaultHttpClient(connManager,
                params);
        try {
            int proxyPort = YOUR_PROXY_PORT;
            String proxyHost = "YOUR_PROXT_HOST_NAME";
            if (proxyPort > 0 && proxyHost != null && proxyHost.length() > 0) {
                System.setProperty("https.proxyHost", proxyHost);
                System.setProperty("https.proxyPort", proxyPort + "");
                System.setProperty("http.proxyHost", proxyHost);
                System.setProperty("http.proxyPort", proxyPort + "");
                HttpHost proxy = new HttpHost(proxyHost, proxyPort);
                httpClient.getParams().setParameter(
                        ConnRoutePNames.DEFAULT_PROXY, proxy);
            }
        } catch (NullPointerException e) {
            System.out.println("Proxy error here");
        }
        return httpClient;
    }


    public static HttpTransport myNetHttpTransport()
                throws Exception {
            return new ApacheHttpTransport(myHttpClient());
        }

use .setTransport(myNetHttpTransport()) instead of NetHttpTransport() .

we spent long time on this. but as of now this seems to be working. Please let me know if any help in this...
