certpath.SunCertPathBuilderException: unable to find valid certification path


A continuación el ejemplo que hice :



[German@KDU ssl]$ java -cp . SSLPoke 
Utility to debug Java connections to SSL servers
Usage: 
  java SSLPoke
or for more debugging:
  java -Djavax.net.debug=ssl SSLPoke

Eg. to test the SSL certificate at https://localhost, use
  java SSLPoke localhost 443
[German@KDU ssl]$ java -cp . SSLPoke 127.0.0.1 7002

[German@KDU ssl]$ 
[German@KDU ssl]$ java -cp . -Djavax.net.ssl.trustStore=/Users/German/Oracle/Middleware/Oracle_Home/wlserver/server/lib/DemoTrust.jks SSLPoke 127.0.0.1 7002 
Successfully connected
[German@KDU ssl]$ 

como era de esperar uno de los problemas clasicos es setear el trust store en el java system properties, ademas algunos otros properties de ayuda para debug ssl :

-Djavax.net.debug=ssl
-Djavax.net.ssl.keyStoreType=pkcs12
-Djavax.net.ssl.keyStore=client.p12
-Djavax.net.ssl.keyStorePassword=whatever
-Djavax.net.ssl.trustStoreType=jks
-Djavax.net.ssl.trustStore=client-truststore.jks
-Djavax.net.ssl.trustStorePassword=whatever
