In a Java desktop application I need to connect to a SSL URL. When I try it, I get the exception:
SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target
To solve it, I go to the address with my browser, download the certificate in .cert file and import in my java cacerts keystore using keytool command. After this, the application works fine.
My question is: why java don't recognize the certificate if this is signed with VeriSign? VeriSign certificate is not installed in cacerts keystore by default? Maybe I don't understand how SSL works. What's the difference between browser and java desktop behavior? I can connect to this URL with my browser without installing nothing.
Thanks
