Hey Bradley,
a) mark application as priviliged=true
b) define and implement your own ClusterMessage
c) via MbeansServer you got the Catalina:type=Cluster,host=localhost
mbean and send your
operation ( send(ClusterMessage)).
d) Register a ClusterListener.
with 5.5.11 you can configure this directly inside Cluster
element.
with 5.5.9 you must implement you own host listener to
register a ClusterListener.
I am motivate to implement a simple sample and add this to the tomcat docs..

this is a good question. i'll be facing the same issue soon. for
session-based information, your answer is fine, but what about other
types of info, say at the app-level? in one of my apps, for example, I
can change some config data using a web request, but what if i want to
ensure it is replicated to the other nodes in the cluster?

Hi,
Why do you want your application to send a notification ?
If you configure Session Replication in each of your Tomcat servers,
every time there will be a change in your HTTP session, the others AS in the cluster will be notified and synchronized automatically.
You have nothing to do...

Hi,
I have successfully installed a Tomcat cluster :)
I need to notify other nodes in the cluster when a
state is changed in my web application. My problem is
that I don't know how to send those notifications.
I've found one reply to similar question: "You can
register your own Cluster Message Listener and with
SimpleTcpCluster.send(ClusterMessage) you can send
your message to all cluster nodes."
How is that done in practice? Does someone have an
example how to get the reference to that
SimpleTcpCluster instance?
Any help is appreciated :)
Thanks,
Eino
