Share a spring bean on a Tomcat cluster

[clement]

Hello,

I'm working on a java/Spring application. One bean is used to manage datas in a map and push async messages
when a data is removed from the map. This working quite well but I wonder how this can work if I have to put several tomcat in cluster on a production environment later.
Now, a synchronized method allow users to add/get/remove datas in the map (which is a field of the bean).
As it works well, I would like to know the easiest way to share this bean between several tomcat server ?

Thank you very much for your help !
