So TOR is NOT really anonoymous!?

[Uhuru]

I set up TOR (the onion router) and privoxy hoping to browse anonymously,
I am using Mozilla Firefox 1.0.6 and if I visit other site such as:
http://www.showmyip.com/
TOR works properly.

BUT if I check here:
http://www.inet-police.com/cgi-bin/env.cgi
they show my REAL IP  address!

So TOR is NOT  really anonoymous!?

later on I discovered by myself that if I disable java in Firefox
settings then even
http://www.inet-police.com/cgi-bin/env.cgi
cannot read my Real IP address.
So I have to keep java always turned off?
