Java: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

Question

I have a class that will download a file from a https server. When I run it, it returns a lot of errors. It seems that I have a problem with my certificate

Answer 1

You have two options, import the self-signed cert into java's keystore for each jvm the software will run on or try the non-validating ssl factory:

jdbc:postgresql://myserver.com:5432/mydatabasename?ssl=true&sslfactory=org.postgresql.ssl.NonValidatingFactory
