If you are experiencing an issue please mention the full platform your
issue applies to:
IDE: Eclipse
Desktop OS: linux
We have a web project which is always working fine, it just using codename
one push api to push notification to our devices, but it suddenly get the
following error: "javax.net.ssl.SSLHandshakeException: Received fatal
alert: handshake_failure", no mattter at local, UAT or Prod server.
Below is the core code (same with codenamoe one demo), I just create a
function to call it.
HttpURLConnection connection = (HttpURLConnection)new
URL("https://push.codenameone.com/push/push";).openConnection();
connection.setDoOutput(true);
connection.setRequestMethod("POST");
connection.setRequestProperty("Content-Type",
"application/x-www-form-urlencoded;charset=UTF-8");String cert =
ITUNES_DEVELOPMENT_PUSH_CERT;String pass =
ITUNES_DEVELOPMENT_PUSH_CERT_PASSWORD;if(ITUNES_PRODUCTION_PUSH) {
cert = ITUNES_PRODUCTION_PUSH_CERT;
pass = ITUNES_PRODUCTION_PUSH_CERT_PASSWORD;}String query = "token=" +
PUSH_TOKEN +
"&device=" + URLEncoder.encode(deviceId1, "UTF-8") +
"&device=" + URLEncoder.encode(deviceId2, "UTF-8") +
"&device=" + URLEncoder.encode(deviceId3, "UTF-8") +
"&type=1" +
"&auth=" + URLEncoder.encode(FCM_SERVER_API_KEY, "UTF-8") +
"&certPassword=" + URLEncoder.encode(pass, "UTF-8") +
"&cert=" + URLEncoder.encode(cert, "UTF-8") +
"&body=" + URLEncoder.encode(MESSAGE_BODY, "UTF-8") +
"&production=" + ITUNES_PRODUCTION_PUSH +
"&sid=" + URLEncoder.encode(WNS_SID, "UTF-8") +
"&client_secret=" + URLEncoder.encode(WNS_CLIENT_SECRET, "UTF-8");try
(OutputStream output = connection.getOutputStream()) {
output.write(query.getBytes("UTF-8"));}int c =
connection.getResponseCode();// read response JSON
I directly run the code in unit test(localhost), it works well.
But when I call the function from project (such as a button from webpage),
the error happened.
The error happened when run "OutputStream output = connection.
getOutputStream()", I never change any code about it, the error suddenly
happened from yesterday.
I tried several way to solve it but still can not work, please give me some
suggestion to fix the issue. Thank you!
