pls i am deploying my aplication in a clustered server (weblogic) environment .pls i would like to ask if in using clustering u will have to call remote home objects in ur code rather than local home objects. i would pefer local due to better performance .but since i am deploying on different machines, should i then call remote methods from the remote home objects or does it matter? thanks

You can always use the local interfaces. WL uses cluster-aware stubs when clustering is enable. This means that the stub implements the routing algorithm (which by default is the round-robin) and it will forward the request to the next server instance in the cluster. However WL will always bypass the routing algorithm if the request originates from within the container. WL will redirect the request to the same instance to improve the performances. Bottom line is that your request (from one ejb to another) will never leave the server instance, no matter whether you�re using remote or local interfaces. The only difference is that using the remote calls will add the extra RMI overhead. Regards
