When using SSL in Scriptura, the following error can occur :
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 target
The solution is to include the missing root certificate in the java truststore. More information can be found in http://magicmonster.com/kb/prg/java/ssl/pkix_path_building_failed.html
