Hello guys, this is ane of the mutual fault inward a client-server application. The big work inward solving this fault is non the fault but the noesis of how client-server SSL handshake works. I convey blogged close that earlier in addition to if you lot convey read that you lot know that inward guild to connect to whatsoever website or server (like LDAP Server) using SSL, you lot withdraw to convey certificates (public keys) to validate the certificates sends past times the website you lot are connecting. If you lot don't convey the root certificate or populace key, which is required to validate the certificate presented past times the server inward your JRE truststore in addition to thus Java volition throw this error.
javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path edifice failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to honour valid certification path to requested target
In guild to solve this error, just add together the root certificate required to connect to the server inward enquiry into truststore of your application's JRE.
If you lot don't know, JVM uses 2 files, keystore in addition to truststore to shop the SSL certificates. keystore is to a greater extent than ofttimes than non used past times the server in addition to it contains both mortal in addition to populace key, piece truststore is to a greater extent than ofttimes than non used on client-side in addition to contains the populace fundamental of the server.
One to a greater extent than challenge hither could hold out for beginners to honour which version of JRE their application is using in addition to what is the PATH for it. This is real of import because you lot withdraw to ascertain which trust shop your application is using? Is it using default truststore coming amongst JRE? or it has its ain truststore created?
It's possible to instruct JVM to alternative an alternative truststore past times using or thus JVM arguments. For example, if you lot desire your Tomcat to alternative certificates from a specific truststore, you lot tin add together the next lines into CATALINA startup files:
-Djavax.net.ssl.keyStore=%CLIENT_CERT%
-Djavax.net.ssl.keyStorePassword=changeit
-Djavax.net.ssl.trustStore=%CLIENT_CERT%
-Djavax.net.ssl.trustStorePassword=changeit
Once you lot ascertain that which JRE in addition to truststore your Java application is using, the side past times side measurement is to upgrade the root certificate on the truststore. See The Complete Java Masterclass to learn to a greater extent than close truststore in addition to keystore in addition to other safety features of Java.
how create you lot acquire the root certificate? Well, your Java cacerts which comes along JRE already contains the root certificate for most of CA (Certificate authority) which is acting inward populace domain similar Verisign, Thwate, if you lot are internally connecting to ane of the servers, you lot withdraw the root certificate issued past times your company. You tin verbalize to your SSL admins or Infra squad for that.
Once you lot got the root certificate, to a greater extent than ofttimes than non a file amongst something abc.cer, you lot tin role the keytool command to add together that certificate into truststore used past times your application similar cacerts from JRE/security/lib folder.
You tin role the next keytool ascendancy to add together certificates into keystore/truststore :
$ keytool -import -alias -ca -file /tmp/root_cert.cer -keystore cacerts
movement into the password every bit changeit, this default password for cacerts from JRE.
Now, your final result should hold out sorted.
Though, you lot withdraw to retrieve to supercede the certificate inward your truststore when the server does the certificate upgrade. For example, Recently, ane of user reported that their companionship migrated from SHA-1 certificate to SHA-2 certificate in addition to it started seeing this fault until he added the SHA-2 certificates on the trust shop of his application.
