Clustering question

I'm using both local and remote interfeces for client facing EJBs. Web app. uses local interface and the swing uses remote interface. If we cluster this application, can the web application talk to another node instance in the cluster...?

Local interfaces imply that both client and EJB container are running in the same JVM (as a consequence, the same node). If you plan to cluster specifically business layer, you probably wouldn't be able to use local interfaces.

I have decided to cluster in the web application level, keeping the web app and ejb as a single module.

Thanks for the reply.

Steve are you thinking about running several instances of the app server? There's only one machine for the app server so I'm not sure what clustering yo ave in mind.
I agree. Here's the link:
