Hello, The sample code expects a truststore file named my.keystore in the current runtime directory with password „nopassword“, you need to provide one it seems. I guess if you use official certificates you don’t need that part of the customization.
The Java keytool command can be used to import certificates into new keystore files. BTW it might be easier to hire someone with Java experience.
