Hi,
You cannot achieve this using the tcServer session replication module due to the requirements of its component layout in the classpath hierarchy. However, we also have a generic 'AppServer' session module which you might try and use for this. This module uses filtering to achieve session replication and gets integrated by configuring your web.xml. This module allows you to split up your dependent jars if desired, however, in this case you would have to bundle all the necessary jars into your war. Essentially, what this means is that each webapp would have it's own gemfire.jar and would thus be creating separate caches within a single JVM. You would still need to use either a peer-to-peer topology or, if using client-server, you would not want to have local caches for each client.
