hi all,

i have developed a web service(https based) client which is running on my 4 servers.i am facing a issue on a server like this.

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

while client on all other 3 server is running but that single server is creating problem.i have installed the same certificate to all server.

Please suggest what the issue may be.
