I am a newbie to MBeans and JMX. Here is my scenario and I would like some suggestions on what reading materials I should be looking at:
Our product, so far, runs on a single JBoss instance (no cluster stuff). It has two WAR files (main.war and depends.war). Both Depends and Main are MBeans. Depends notifies Main about its status once in a while. As long as they are in the same MBean server, it works great.
Now, we are starting to look at a clustered environment which implies a single Main and multiple Depends with each Depend talking back to Main upon each hit from the client/user. Since I need failover, I obviously would have a Singleton Main MBean (as described in http://www.onjava.com/pub/a/onjava/2003/08/20/jboss_clustering.html).
So, is there something else I need to consider before I get into this environment? There are no EJBs to be worried about in my case. Is there some reading material which I can look into before I start clustering other than the JBoss Clustering doc?
