Answer 1

In my case I was facing the problem because in my tomcat process specific keystore was given using

-Djavax.net.ssl.trustStore=/pathtosomeselfsignedstore/truststore.jks

Wheras I was importing the certificate to the cacert of JRE/lib/security and the changes were not reflecting. Then I did below command where /tmp/cert1.test contains the certificate of the target server

keytool -import -trustcacerts -keystore /pathtosomeselfsignedstore/truststore.jks -storepass password123 -noprompt -alias rapidssl-myserver -file /tmp/cert1.test

We can double check if the certificate import is successful

keytool -list -v -keystore /pathtosomeselfsignedstore/truststore.jks

and see if your taget server is found against alias rapidssl-myserver
