Peter, Thanks for response. I did not implement my own replication, I only looked at the code to see if my Context was started before the Cluster performed replication. Let me try and clarify by asking this question:
Does the Context start (meaning my servlet is started) before the Delta manager syncs with other nodes? It appears the Context is not started before the Sessions are received. If this is true, this is why I am having issues. This is because when Sessions are received, they are deserialized before the web application is loaded. Inside my sessions, I have factory objects loaded via JNDI. These JNDI references are not found. This only occurs when Clustering my sessions. I hope that makes sense. --- Peter Rossbach <[EMAIL PROTECTED]> wrote: > Hey, > > a) current tomcat 5.5.12 cluster implementation is a message > infrastructure. > b) The Context can used this message infrastructure to implement > remote session replication > c) When a Context start the DeltaManager sync with other nodes.
