Calling web service: javax.net.ssl.SSLException: Received fatal alert: protocol_version
问题 I debugged ssl handshake, by the log I suppose both server and client uses TLSv1. Even tried setting System.setProperty("https.protocols", "TLSv1"); still no success. I'm unable to figure out the exact cause of this problem. Can anyone please guide me on this. I'm using Java 1.7.0_65 keyStore is : keyStore type is : jks keyStore provider is : init keystore init keymanager of type SunX509 trustStore is: E:\Java\jdk1.7.0_65\jre\lib\security\cacerts trustStore type is : jks trustStore provider
