Java program written by Andreas Sterbenz, and posted on a blog in Oct, 2006: https://blogs.oracle.com/gc/entry/unable_to_find_valid_certification

Link to Java program in Andreas' blog no longer works, but the source was linked in another blog: http://nodsw.com/blog/leeland/2006/12/06-no-more-unable-find-valid-certification-path-requested-target

Usage: Need to compile, first: javac InstallCert.java

Access server, and retrieve certificate (accept default certificate 1)

java InstallCert [host]:[port]

Extract certificate from created jssecacerts keystore

keytool -exportcert -alias [host]-1 -keystore jssecacerts -storepass changeit -file [host].cer

Import certificate into system keystore

keytool -importcert -alias [host] -keystore [path to system keystore] -storepass changeit -file [host].cer

Example:

java InstallCert woot.com:443

Loading KeyStore /usr/lib/jvm/java-6-sun-1.6.0.26/jre/lib/security/cacerts...
Opening connection to woot.com:443...
Starting SSL handshake...

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
