i have three java based web application app1,app2 and app3 at production. All 3 are verified by verified CA’s and hosted on 3 different web servers
and on https.
app1,app2 is verified by secure trust.app3 is verified by trustwave .
Below is the hierarchy of certificates of certificates ,i can see when i hit any of these app thru web browser.
app1,app2 certificate hirerarchy is same .e
Entrust.net Secure Server Certification Authority---> SecureTrust CA------->*.myAppDomain.com
app3 certificate hirerarchy is
Entrust.net Secure Server Certification Authority---> SecureTrust CA------->TrustWave Organization Validation CA, L------->*.myApp3.com
Now when app1 connect to app2 , works fine. But when app1 connects to app3 gets below exception
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
Now i had a look on cacert file(i.e trust store) inside jdk on web server hosting app1 . I tried to found the entries for Entrust,SecureTrust,TrustWave but found only entries like entrustevca, entrust2048ca etc. So if i go by the logic that if root certificate (which is Entrust for both the applications app2 and app3 ) lies in trust store of contacting application(app3) ,which i can see in cacert file on app3 ,then i should not get the above mentioned error when app1 tries to contact app3 thru httpsURLConnection. I am not gettting the cause of this? i am not sure do we need to include the trustwave also , though the root certificate i.e Entrust which internally authenticate trustwave already there?
If i need to include trustwave certificate(used by app2) in cacert file on app3 then by that logic i should also inlcude
securetrust(used by app2) in cacert file on app3 but it is working Fine?
The client’s truststore doesn’t trust the server’s certificate. So there was no trusted CA certificate in the client’s truststore that matched anything in the certificate chain supplied by the server. So that certificate chain was incomplete. You need to import everything you were supplied with by the CA into the server’s keystore.
