Not clustered, can be used from multiple nodes and can be serviced from
multiple nodes but there is no failover of data if one node goes down yet.

Not clustered, must be serviced from one node but can be used from multiple
nodes.

ServletContext and session data are replicated, the data (beans) must be
serializable or EJB references or similar, this will be specified in detail
in the Servlet 2.3 spec.

JNDI is clustered within a cluster so a lookup finds an instance if it
resides in any of the nodes in the cluster.

Clients can have multiple ORMI urls specified in provider.url (comma
separated) to try other hosts if one goes down.

We havent tried that one so we dont know. If it forwards incoming socket
requests in a round-robin or other manner then yes, it should work.
