In tomcat 6, maybe 5.5.x we will have a ReplicatedContext, meaning that the context attributes are replicated. So you can store data in the ServletContext and it will be available on the other nodes.

In your situation right now, you can use the Tomcat "Tribes" module for communicating between nodes, or other options are Appia, Spread and JGroups.

Hi,
I have a situation that requires some information  be shared across a cluster.
 The issue is that the classes that manage this info are not particular to a
given session but global to the application such that at session on all
servers in the cluster would need to read/write to these classes.
I am wondering if there's a way to do this with the Clustering support
directly or would I need to use JGroups or something like that.

THanks
