Can you check whether your OS and java runtime are 32-bit or 64-bit from within your program?

Basically I need to see what version of the OS and Java i'm running so I can copy the correct DLLs to the run directory. As always, a better solution is appreciated.

You can check JRE version checkin os.arch property of System class

JNLP - Java Web Start - allows for specifying DLL's and shared libraries per architecture. This allows you to do centralized distribution with a local icon for the users to click.
