[pinga kanave]

I want to setup apache tomcat on my linux distribution .

I Have downloaded apache tomcat from below mentioned link.

Core:
http://tomcat.apache.org/download-55.cgi
The setup was in following format.
apache-tomcat-5.5.29.tar.gz

Below are the command i have used to install the software.
I have copied the file to / directory
Run following commands.

gunzip apache-tomcat-5.5.29.tar.gz
tar -xvf apache-tomcat-5.5.29.tar

Now there is a folder called apache-tomcat-5.5.29 in my root directory.
Now whenever i run startup.sh .It says

"Neither the JAVA_HOME nor the JRE_HOME environment variable is defined
At least one of these environment variable is needed to run this program
" 

What should be the next step?

I m currently stuck at this step .What should be my next step. i had no trouble installing it on my windows box but since i m new to linux request you to help me install it.

How do i install jre-6u20-linux-i586-rpm.bin file .

I have created java folder in /usr
now whenever i execute jre-6u20-linux-i586-rpm.bin using rpm -i jre-6u20-linux-i586-rpm.bin i get following error:

jre-6u20-linux-i586-rpm.bin: not an rpm package (or package manifest):

What should i do I only have terminal access (not gui access to the server).

Thanks i have installed the bin file successfully also able to run startup.sh.

./startup.sh
Using CATALINA_BASE: /apache-tomcat-5.5.29
Using CATALINA_HOME: /apache-tomcat-5.5.29
Using CATALINA_TMPDIR: /apache-tomcat-5.5.29/temp
Using JRE_HOME: /usr/java/jre1.6.0_20
Using CLASSPATH: /apache-tomcat-5.5.29/bin/bootstrap.jar


Finally I got it working All i need to do is to disable the firewall as it was blocking port 8080

Now whenever i click on admin page and enter default user as admin password blank it says invalid password.

I have not done any changes to password file ?
Have they changed the default user/password ?
