Subject Re: another problem with session replication
Date Tue, 07 Dec 2004 10:34:17 GMT
Hi,
You replied yesterday suggesting that my problem regaring session state 
replication on tomcat restart was caused by multicasting not working in my 
network.
Well, except from state not being replicated on restart, all mcast messages 
are past between the members correctly from then on. And my application is 
using clustering with JGroups for fileuploads/locks etc. updates which is 
using multicasting, and this is working sweet. So how can the problem then 
being cause by network multicasting problems, and do you have any idea how/ 
why a clustermember receives mcast messages on attribute changes but not 
asking for session state when starting.  What am i missing? I really need to 
figure this because of login issues.

Thanks,
Ina!
