Hi Guys,

I appear to be finally getting somewhere with the in-memory state
replication but am now getting the following error when starting up
my tomcat instances/

WARNING: Manager [/jsp-examples], requesting session state from

Can anyone point me in the right direction as to why the session
state is not being replicated ?
Two things to check:
1. What does the other server log say, maybe there is an error there, does the other server know of this server?
2. your server.xml, you would need to provide us with a little bit
more info

I might be being a bit thick here !!!

I have 3 servers !

One is running apache2, mod_jk2 and tomcat-5.5.17, the other two just
have tomcat-5.5.17. Do i need to have apache and mod_jk2 running on all
servers ?

I am sure it would be easier to use mod_proxy_balancer and
mod_proxy_ajp but can't find any documentation anywhere.

Thanks for the help so far guys.
your problem is not related to Apache or mod_jk, its strictly Tomcat. Session state transfer fails.
and that's the path you need to persue.
1. Check all your tomcat logs
2. Make sure that node discovery is working, you should have in each of your tomcat nodes, a info log statement saying it detected the other two nodes.

Filip
