bin\keytool -importkeystore -srckeystore wildcard.keystore -srcstorepass changeit -destkeystore jre\lib\security\cacerts -deststorepass changeit

For Linux

bin/keytool -importkeystore -srckeystore wildcard.keystore -srcstorepass changeit -destkeystore jre/lib/security/cacerts -deststorepass changeit
