Hi,
I am making used of a shared object(singleton) which saves state
amongst multiple clients. This works fine in a single Jaguar Server
environment.

However, if I have multple Jaguar servers running in a cluster, I
would assume each Jaguar server to possibly have an instance of the
shared object. How would I maintain state in such a scenario ??

You'll need to build in a synchonization mechanism. We have done this
in the past using messaging systems like TIBCO.
