Shamshad,
the tomcat clustering docs are in place for session replication, you may
not need that.
What you may need is a load balancer in front of Tomcat, so if one
tomcat goes down, traffic gets redirected to another.
this can be accomplished with an appliance like netscaler, f5 bigip, etc.
or you can use the apache webserver (httpd) and mod_jk or mod_proxy_balancer

Is it acceptable for users to have to re-login in the event of a server
failure? If so, you can just set up simply clustering via mod_jk, which
binds a particular session to a single back-end machine. You don't have
to use distributable sessions or worry about sending data around the
cluster so the data is available everywhere just in case a server goes down.

You should definitely start here:
http://tomcat.apache.org/tomcat-6.0-doc/cluster-howto.html
There is quite a bit of information in there, including background info
and step-by-step instructions.
