sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

  • So you've got a `SSLHandshakeException` because of `ValidatorException` with keywords "PKIX path" and "valid certification path" and you are too lazy to run a Google search. OK. Short story: you try to connect to a remote server using a secure SSL connection; the Java network library checks the server certificate; but it is not signed by a **public authority** (e.g. VeriSign) that is listed in the JRE system TrustStore; and you did not provide a **custom** TrustStore file; therefore Java refuses to connect to an insecure site *(could be a spoofing attack! oh my!)* – Samson Scharfrichter Aug 18 '16 at 14:07
