Sorry, I meant / not .
I have this running on a two node cluster, and even though the logs show
this message on both nodes in catalina.out, I know that the data is
replicating. I can shutdown one node, and the session data has persisted on
the other.
Here is the log message:
[InMemoryReplicationManager] Failed to deserialize the session!

it should be in
WEB-INF/classes/some/package/Employee.class is that what you meant?
never had this problem myself, what version of Tomcat? also, can you send
the log trace for this
