Java and SSL certificates

Question

I am trying to establish a connection with a PHP script of mine in Java using the secure socket layer (HTTPS), but I have found out that to ensure maximum security/validity

Answer 1

I have found out that to ensure maxium security/validity I have to import the SSL certificate

No you don't. You only need that step if your clients don't already trust the signer of the server certificate, which only arises if the server certificate is self-signed or signed e.g. by an internal CA.
