I have some Java code running that has to open a https page and fetch data, which has been running for the last 7-8 years. The only thing i do once every 2 years is to update the certificate in Java. In May the certificate was updated on the page, which i have updated locally afterwards, but suddenly something has gone completely wrong.
I currently run JRE6 but in my desperate attempt to see if Java was borked i installed JRE7 and reinstalled the certificate, but without any luck at all.
The exception is:
sun.security.validator.ValidatorException: PKIX path building failed:
sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target
I have checked the cacerts file and it has the certificate which is neccessary. Furthermore i have even tried to insure myself by using InstallCert.java utility, but it verified that i have been using the correct certificate all along. I contacted the page owner and they had not heard of any unusual problems with their certificate.
So basically, what or which procedure havent i tried?
