Google Checkout Account has 'PKIX path building failed' errors in the Integration section

An error is encountered when attempting to access your server at

sun.security.validator.ValidatorException: PKIX path building failed: 
sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

This is caused by using an SSL certificate that Google does not accept.

Use an SSL certificate from one of the Certificate Authorities that Google accepts, listed at http://checkout.google.com/support/sell/bin/answer.py?answer=57856
