JRE 32bit or 64 bit?

[Sri Harsha Yenuganti]

How can I check whether the JRE on my system is a 32bit or 64 bit? I am using Red Hat Linux.

System.getProperty("os.arch");

Run: java -version
On my machine it gives me this:

OpenJDK Runtime Environment (IcedTea6 1.6.1) (6b16-1.6.1-3ubuntu3)
OpenJDK 64-Bit Server VM build 14.0-b16, mixed mode)
