Javax.Net.Ssl.Sslhandshakeexception: Sun.Security.Validator.Validatorexception: Pkix Path Edifice Failed: Sun.Security.Provider.Certpath.Suncertpathbuilderexception: Unable To Notice Valid Certification Path To Requested Target

Hello guys, this is i of the mutual mistake inwards a client-server application. The big work inwards solving this mistake is non the mistake but the cognition of how client-server SSL handshake works. I accept blogged most that earlier as well as if you lot accept read that you lot know that inwards social club to connect to whatever website or server (like LDAP Server) using SSL, you lot cry for to accept certificates (public keys) to validate the certificates sends past times the website you lot are connecting. If you lot don't accept the root certificate or populace key, which is required to validate the certificate presented past times the server inwards your JRE truststore as well as then Java volition throw this error.

javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path edifice failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to uncovering valid certification path to requested target

In social club to solve this error, just add together the root certificate required to connect to the server inwards interrogation into truststore of your application's JRE.

If you lot don't know, JVM uses ii files, keystore as well as truststore to shop the SSL certificates. keystore is to a greater extent than oft than non used past times the server as well as it contains both mortal as well as populace key, piece truststore is to a greater extent than oft than non used on client-side as well as contains the populace telephone substitution of the server.

One to a greater extent than challenge hither could survive for beginners to uncovering which version of JRE their application is using as well as what is the PATH for it. This is really of import because you lot cry for 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 selection an choice truststore past times using around JVM arguments. For example, if you lot desire your Tomcat to selection 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 as well as 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 most truststore as well as keystore as well as other safety features of Java.

 this is i of the mutual mistake inwards a customer javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path edifice failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to uncovering valid certification path to requested target


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 inwards populace domain similar Verisign, Thwate, if you lot are internally connecting to i of the servers, you lot cry for the root certificate issued past times your company. You tin speak to your SSL admins or Infra squad for that.

Once you lot got the root certificate, to a greater extent than oft 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 ascendency to add together certificates into keystore/truststore :

$ keytool -import -alias -ca -file /tmp/root_cert.cer -keystore cacerts

move into the password every bit changeit, this default password for cacerts from JRE.

Now, your effect should survive sorted.

Though, you lot cry for to recall to supercede the certificate inwards your truststore when the server does the certificate upgrade. For example, Recently, i of user reported that their fellowship migrated from SHA-1 certificate to SHA-2 certificate as well as it started seeing this mistake until he added the SHA-2 certificates on the trust shop of his application.
