 export CLASSPATH=/u01/app/jdk/lib/tools.jar:/u01/app/Oracle/Middleware/Oracle_Home/wlserver/server/lib/weblogic.jar

openssl pkcs12 -in mycertficate.pfx -out KEYSTORE.pem -nodes

-----END CERTIFICATE-----

Make sure you have both pfx and private key files with password

/u01/app/jdk/bin/keytool -import -trustcacerts -file Certificate.pem -alias mycertficate -keystore truststore.jks -storepass changeit -keypass changeit

java utils.ImportPrivateKey -keystore keystore.jks -storepass changeit -storetype JKS -keypass changeit -alias mycertficate -certfile Certificate.pem -keyfile Privatekey.pem -keyfilepass C0mm0NC3rt##2024

Now you should have both truststore.jks and keystore.jks
