Java installation problem.

[mckagan at gmail.com (duffmckagan)]

I downloaded the   jre-1_5_0_01-linux-i586-rpm.bin    files and then 
run it as   ./jre-1_5_0_01-linux-i586-rpm.bin.

It resulted in an rpm file. and then i used
rpm -iv jre-1_5_0_01-linux-i586-rpm 

Everything went fine and I didn't get any error.
But when I do 
java -version    ......i don't get any output.

I would like to know whether java is installed on my system or not.

PS: I have carried out all the proceses as root.
