Answer 1

I've lost so many days searching for a solution, and this post was helps to me. I had the same problem. I created a pem file like here, and then, the cert file .pem, was incrusted in cacert file (a copy called TrustStore.jks) with this command:

keytool.exe -import -noprompt -keystore TrustStore.jks -storepass changeit ^ -alias DOMAINNAME -file MYCERTFILE.pem

(DOMAINNAME must be replace by hostname -this trick is very important-, and MYCERTFILE by file recent create...)

I hope that this solution can helps to somebody.
