From http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6717199 "I believe RSA Technologies (http://www.rsa.com) now owns the Valicert Class 3 CA Certificate. We have a more formal process for incorporating root certificates into the JDK, and it is usually initiated by the CA vendor and involves agreements with the CA vendor. At this time we don't have plans to incorporate this root certificate into the JDK. I would suggest contacting RSA and letting them know that you would like to see this certificate in the JDK." Sigh. So it's the expected result. For now, please set your trust anchor by yourself. For example, it should work on Ubuntu system. client.ssl_config.set_trust_ca("/etc/ssl/certs") Regards, // NaHi
