I am using spring portlet mvc as my front end and connecting to some remote EJB running on a WAS. Now in my configuration file for the portlet where I specify the remote EJB lookup url, I have specified the url(s) as a cluster since the EJB is deployed in a clustered WAS. So the url looks like :iiop://server1:port,iiop://server2:port
.
Now to save resources, spring mvc caches the initial context.Now I am noticing that spring is always able to make a connection to the remote ejb so long as one of the servers is up.
This is confusing to me since the cluster is resolved(for lack of a better word) at the time of lookup of the initial context and after that if the cluster member goes down, there should be a connection exception. So how does spring know when it should automatically refresh its initial context because the old context has become stale?
