If you wanted to do it manually, what would it do?

1. it would download something from Sun.

2. You would execute the download.

3. you would type into the installer to tell it where to go.

If I were tackling this, first I would scour the docs of the installer
to see if you could control it with command line switches.  Then all
you need do is spawn it with exec from a signed applet.

Failing that I would look at the Robot class to see if it lets you
remotely control such an installer.

Failing that, I would look at the Windows API to see if I could
control another app, simulating a user. Then I would write JNI to let
me at that API from Java.

Failing that, I would install the package and see just what files it
puts where, and what it does to the registry.  I would then write my
own installer that duplicated that, not using Sun's installer at all.

Failing that, I would have a look at The Transporter, an encryption
package without any restrictions on it no batter how many bits you put
in your key, that does not require JCE.
