Yes your application classes from war/ear should be deployed to all nodes. I'd start investigation with domain deployment https://docs.jboss.org/author/display/AS7/Application+deployment
Hi Vladimir, thanks very much for the pointer.
so this means the only way to deploy code to run on the cluster is to take down the nodes where the new code is deployed, losing the data that's in memory (if it's not passivated, etc), right?
are there plans in the future for some kind of dynamic classloading for execution across the cluster (i.e. so arbitrary code can be run across the grid) ?
also is there a way i can connect to the grid as an 'observer' that does not want any local cache entries but merely wants to use the distributed execution service?
Yeah I thought of something like that. I will look into it in the meantime. Thanks
