Web container lacks cluster replication of application scope ------------------------------------------------------------ Key: JBCLUSTER-86 URL: http://jira.jboss.com/jira/browse/JBCLUSTER-86 Project: JBoss Clustering Issue Type: Feature Request Security Level: Public(Everyone can see) Components: Web Tier Affects Versions: Q2Y5 Reporter: treespace Assigned To: Brian Stansberry Replication of servlet contexts (a.k.a. appliction scope) are not supported by the servlet specification. That is an important fact that needs to be emphased in cluster related documentation. Applications need to be cluster-aware at some level so this is just another design issue that needs to be accomodated. An extra-specification feature to cluster the servlet context would be peachy. Generalizing a shared object that hides the underlying cache implementation could provide a more portable alternative: getServletContext().getAttribute(MAGIC_BEAN).setAttribute("myBroadcastMessage", "All your servlet contexts are belong to us!"); To port the application you would need a port of the MAGIC_BEAN class to use whatever clustering facilities are available on the target platform.
