That's what I needed to know, thank you. (And thanks to whoever
responded to my query via the developer support page.) I gathered from
one of the reference pages that the blog post mentioned that any Java
version from 1.4.2 on should work, presumably...
I just tested with test.authorize.net instead of secure.authorize.net
and had no problems. Using Java 7 but didn't install any of the new
certificates. Is test.authorize.net already enforcing SHA-2 or do I have
to create a sandbox account?
