Tomcat4.x cluster setup

Can someone point me to a step by step setup process for Clustering Tomcat4.x? The Tomcat documentations that i saw, only talk about Tomcat5.x clustering configurations

Thank you.

Are you sure Tomcat 4x supports clustering?

This is what i got from an article on Tomcat Clustering:

Clustering was available in the previous Tomcat version (version 4.1) as a third-party JAR file; it wasn't very easy to install or configure to make multiple Tomcat instances run in a cluster. JavaGroups is a popular choice for adding clustering capabilities in open source servlet containers (Tomcat) and application servers (JBoss). But in the latest version of Tomcat server, clustering comes as part of the main installation package. This minimizes all of the extra effort that goes into integrating third-party clustering implementations into the Tomcat server.

However, i could not find a detailed explanation as to how to set it up.
Reason why i am trying clustering with Tomcat4, is that we already have an application running on that version.

Personally I found the transition from Tomcat 4 to Tomcat 5.5.9 went very smoothly, you might give it a try.

Will certainly give it a try. Thanks all

I had asked the same question on the Tomcat users list and here's the reply that i got:

clustering in 4.x was only experimental, and probably has a load of bugs

So, moving to Tomcat-5.x for clustering is definitely what i'll be doing
