Enable Java in Tor Browser

Hi
There are certain websites blocked in my area and I use Tor to access them. Some of these websites require Java and these websites give error that either java is not installed or disabled. How can I enable Java for Tor Browser?
P.S: I am using linux os.
Regards

Please do not use Java in Tor sessions unless you want some lamer to pwn your system.

1 - it probably won't go through Tor but clearnet
2 - it is a known security hazard
3 - there are published exploits for Java via Tor sessions
