Site certificate problem

["Brian Engel" <Brian.Engel@xxxxxxxxxxx>]

 

Wondering if someone could help me out with this...

 

 

We have been regularly making SSL socket connections to a https site. Now all of a sudden they no longer work. It appears that the site had updated their SSL certificate.

 

I have tried importing their site certificate into the cacerts file with no success.

 

 

Here is the exact error I am getting...

 

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

 

 

I am not entirely sure what this means.  Can anyone provide some insight?

 

 

Thanks in advance.....
