Cross Cluster Notification


I've implemented a web application, which contains configuration data stored as context parameters in the web.xml file. This works fine for a single server environment as you can administrate these parameters via the visual admin tool. But when the application will be deployed to a multiple server evironment, the configuration changes have to be made for every server node via the visual admin tool, what might be error-prone. I thought about storing the data in the cluster's database, but I don't want to execute a sql statement every time the parameters have to be read, so I need some kind of notification mechanism to notify the distributed apps when a parameter has changed (comparable to the INotificationService of the EP). Does anyone have an idea how to achieve this or is there already such a mechanism implemented within J2EE engine?

Thx in advance and best regards
