Hi Mkyong,Thanks for your guide,But when i useHttpClient client = HttpClientBuilder.create.build;HttpGet request = new HttpGet(url);HttpResponse response = client.execute(request);There are a exception atHttpResponse response = client.execute(request);javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException:unable to find valid certification path to requested targetat sun.security.ssl.Alerts.getSSLException(Unknown Source)Could you please help me fix itThanks a lot. I m getting a following eror. I’ve tried both ways: using Apache HttpClient and HttpsURLConnection to connect to my Gmail and get my mail page. But in both cases the result page (when making html file from String result) wasn’t my mail, but it was a permanent loading bar (the same when you connect to Gmail and wait for authentification end).
