Issue when using InstallCert For SSLCertification

问题

I was trying to send a post request on a url from server then it showed following errors

 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

Then I found about InstallCert.java( https://www.cs.ucsb.edu/~pconrad/cs56/examples/ldap/SimpleQuery/InstallCert.java ) which will allow my host and port to send the request. But when I was trying to run it on server it also showed some errors.

 ubuntu@ip-172-31-28-14:/var/lib/tomcat7/webapps$ java InstallCert 52.39.134.231:8080
 Loading KeyStore /usr/lib/jvm/java-7-openjdk-amd64/jre/lib/security/cacerts...
 Opening connection to 52.39.134.231:8080...

Starting SSL handshake...

    at sun.security.ssl.SSLSocketImpl.startHandshake(SSLSocketImpl.java:1355)
    at InstallCert.main(InstallCert.java:91)
 Could not obtain server certificate chain

And now I don't know what to do to send my request.
