Yes I tried and it works fine, but I just want all is automatic.
FarmWarDeployer doesn't do that.
It is a push mechanism rather than a repository of applications queued
for deployment.

I mean, a machine crash, we have to change it.
The new machine has :
1. the same IP
2. the same name
3. the same tomcat configuration (but without the war files already
deployed)
as the previous machine (in order to not restart the load balancer and
not interrupt the service).
The best for me is that all the war in the watchdir of the master node
(the one with watchEnabled="true" ) are deployed in this new machine
because the contexts don't yet exist on this node.
It's only for machine replacement purpose.
For a "real" new node, we are force to reboot the cluster after
declaring the new node in the balancer.
Thanks for helping

All works fine.
I try to add a new war file in the master node folder
"/usr/local/tomcat/watchdir/", after few seconds, the war is correctly deployed
on both nodes.
Now i try to add a third node configured exactily as the slave (i just change
the IP address of receiver to match with the one of the machine). In the master
node log, i can see a new member is added, with the correct IP, but the war
already deployed on the cluster aren't deployed on the new node.
* Question : *
What's the way to be able to auto deploy on new node without restart the
master node ? (when i restart the master node, all the nodes of the cluster are
OK).
Did you try to deploy the app again after the new node has joined?
