Hi,

I am new to J2EE technology and I am writing this J2EE application where I am using stateless session beans to implement few services. This application will run on a cluster of app servers. I need to add MBeans to monitor few resources. One of these resources is "session timeout value". I want to provide an MBean using which I can get the current session timeout value and also set it to desired value.
My query is how should I store this session timeout value so that its available to all the beans running on different nodes in the cluster and any change in its value is reflected in all the nodes.

Thanks,
Tuls.

Tuls,

Look into a clustered cache like JBossCache. In EJB 3.1 you will be able to use clustered singletons (not available yet).

Hope it helps,
Reza
