What am I doing wrong then, or does my scenario just not fit. The application I have is basically a distributed computing server used to run simulations requested by a remote client. I also want to have the loadbalancing, but no replication, so I use HA-JNDI, but set don't set the clustered tag in jboss.xml The architecture is quite simple - each node has the SFSBs to be balanced. A central node is dedicated to serve remote client requests and has the single-cluster jms running. There are two ejbs on the normal nodes, one being a proxy, creating n delegates to split up the workload. Thus, the central server creates an SFSB on a randomly selected server, from where possibly more SFSBs, which should be loadbalanced, may be created. My problem occurs when I want to create 'delegate beans' on the nodes. I start a lookup, and what (probably correctly) happens, is that the Home interface seems to be returned from the local jndi-tree, and consequently the beans as well. Thus, a single job will run only on one node (the one selected by the 'bootstrapping server') with the proxy and a number of delegates it creates. What I would like to have is to distributed the delegates over the cluster. Does this scenario simply not work if all nodes have the same EJBs deployed? Must I then use the clustered-invokers and add my own interceptors (http://www.jboss.com/index.html?module=bb&op=viewtopic&t=80210 - this works fine if I declare the ejbs clustered, but is just unnecessary overhead for my purposes).

I played around with the clustered-ejb configuration in standardjboss.xml trying to disable the state-transfer, but I didn't get it to work (once I stop using StatefulHASessionSynchronisationInterceptor, the session seems to get lost, and I get remote exceptions). If there is a wiki or something, I would be very thankful for a pointer. best, stephan View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4024536#...
