Answer 1

I too had the same problem and was able to fix it. My problem was generating the keystore.p12 file.

If you have a certificate file and private key file, you can generatekeystore.p12 file using following command.

openssl pkcs12 -export -in  -inkey  -out keystore.p12 -name 

You will be prompted for a password,there you can enter a password you like. Once the keystore file is generated copy it to the directory where your .jar file exist.

Following is a working example configuration.

server.port=8443
security.require-ssl=true
server.ssl.key-store-type=PKCS12
server.ssl.key-store=file:keystore.p12
server.ssl.key-store-password=
server.ssl.key-alias=

Note the key store file path file:keystore.p12 if it is going to reside in the same directory as the executable .jar file.
