well here are the classes used: http://svn.apache.org/repos/asf/openejb/trunk/openejb/tomee/tomee-catalina/src/main/java/org/apache/tomee/catalina/cluster/
first we have an observer which is notified when an app is deployed: http://svn.apache.org/repos/asf/openejb/trunk/openejb/tomee/tomee-catalina/src/main/java/org/apache/tomee/catalina/cluster/ClusterObserver.java then we send a deploy messge ( http://svn.apache.org/repos/asf/openejb/trunk/openejb/tomee/tomee-catalina/src/main/java/org/apache/tomee/catalina/cluster/DeployMessage.java ) we have the property (to be configured on all middles) "tomee.cluster.deploy.send-archive" to know if we serialize the archive or if we use file system to share the archive then our tomee has a cluster listener ( http://svn.apache.org/repos/asf/openejb/trunk/openejb/tomee/tomee-catalina/src/main/java/org/apache/tomee/catalina/cluster/TomEEClusterListener.java) which simply call our deployer to do the work. The trick here is to deploy+propagate the deployment only if the app is not already deployed same idea for the undeployment excepted we just need th path to undeploy (= all installations are the same for the moment or use the same file system) *Romain Manni-Bucau* *Twitter: @rmannibucau <https://twitter.com/rmannibucau>* *Blog: **http://rmannibucau.wordpress.com/*<http://rmannibucau.wordpress.com/> *LinkedIn: **http://fr.linkedin.com/in/rmannibucau* *Github: https://github.com/rmannibucau* 2012/10/8 David Blevins <david.blev...@gmail.com> > On Oct 8, 2012, at 10:21 AM, Romain Manni-Bucau wrote: > > > Tomcat cluster events, see cluster packagr of tomee catalina > > Still catching up after JavaOne and crazy travel.
