Java Security

Hi!

I'm trying to do simple https GET from a webserver having a selfsigned 2048 certificate, but it fails since stock java doesn't support > 1024 bits encryption.
I've hit this with 1.6.0_07 and 1.6.0_43, and for both versions, I've tried downloading:
http://www.oracle.com/technetwork/java/javase/downloads/jce-6-download-429243.html

and replacing the two jar files, but with no detectable change. Is there any (simple) way to verify that I actually did install the two files successfully?
is there something else I need to do?

Upgrading java is not an option in the short run..
