hmmm... the default one? Jetty? From todays CVS (jboss-3.0, branch_3_0)
A quick notice:
Jboss is unable to sync sessions, as Rick LaBanca already pointed out and
also sugested a fix:
This would be the cenario:
A starts and replyes to a couple of requests
B starts
A fails to ync state with B, showing this log:
12:17:04,113 INFO [JGStore] initialising another store from our current
state
12:17:04,113 INFO [JGStore] sending 2 sessions
12:17:04,183 ERROR [JGStore] Unable to getState from JavaGroups:

The fix proposed by Rick was to use
public class LocalState implements State, java.io.Serializable
intead of
public class LocalState implements State
in file LocalState.java
I've tested it and it seems to sync up now. Any problem with this aproach?
