Question

I\'m trying to connect a Java Web API via HTTPS; however, an exception is thrown:

javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorExcept         


        

Answer 1

I was having the same problem while importing the certificate in local keystore. Whenever i issue the keytool command i got the following error.

Certificate was added to keystore keytool error: java.io.FileNotFoundException: C:\Program Files\Java\jdk1.8.0_151\jre\lib\security (Access is denied)

Following solution work for me.

1) make sure you are running command prompt in Rus as Administrator mode

2) Change your current directory to %JAVA_HOME%\jre\lib\security

3) then Issue the below command

keytool -import -alias "mycertificatedemo" -file "C:\Users\name\Downloads\abc.crt" -keystore cacerts

3) give the password changeit

4) enter y

5) you will see the following message on successful "Certificate was added to keystore"

Make sure you are giving the "cacerts" only in -keystore param value , as i was giving the full path like "C**:\Program Files\Java\jdk1.8.0_151\jre\lib\security**".

Hope this will work
